##### Gateway 1
Meets Expectations

#### Criterion 1.1: Focus

Materials assess grade-level content and give all students extensive work with grade-level problems to meet the full intent of grade-level standards.

The materials reviewed for Reveal Math Kindergarten meet expectations for focus as they assess grade-level content and provide all students extensive work with grade-level problems to meet the full intent of grade-level standards.

##### Indicator {{'1a' | indicatorName}}

Materials assess the grade-level content and, if applicable, content from earlier grades.

The materials reviewed for Reveal Math Kindergarten meet expectations for assessing grade level content, and if applicable, content from earlier grades. Summative Assessments include Unit Assessments (Forms A and B), Unit Performance Tasks, Benchmark Assessments, and an End of the Year Summative Assessment. Also included in the digital Teacher Center are editable, auto- scored assessments. Reveal Math does include assessments on the faces of three dimensional shapes, which is above grade level. Unit 1 does not include a Unit Assessment or Performance Task.

Examples of grade-level assessment items include:

• In Unit 2, Numbers to 5, Digital Unit Assessment, Form A, Item 5, “Compare the groups. Look at the group of tigers and the group of zebras. Which group is less than the other group?” A group of two tigers and a group of four zebras is displayed. (K.CC.6)

• In Unit 6, Understand Addition, Unit Assessment, Form A, Item 1, “3 butterflies are flying. 4 more join them. Draw butterflies to show how many in all.” (K.OA.1)

• In Unit 10, Numbers 16 to 19, Performance Task, Part E, “Alia takes 18 pennies and puts them in 2 piles. She puts 10 pennies in one pile. How many pennies will be in the other pile? Write the numbers to complete the equation to represent the situation.” (K.NBT.1)

• Benchmark Assessment 3, Item 2, “How many more dots are needed to make 10? [7] Write the number to show how many more dots.” A ten-frame with 3 spaces filled in is shown. (K.OA.3)

• Summative Assessment, Item 7, “Which numbers are missing?  27, 28, __, 30, 31, __, 33. Circle all the correct answers.” The choices are: “26, 29, 32, 34.” [29, 32](K.CC.2)

Example of above grade-level assessment item that could be omitted or modified:

• Summative Assessment, Item 9, A cylinder, a sphere and a cube are shown, “Which solids have faces? Circle all the correct answers.” (K.G.2) Recognizing three-dimensional shapes having specified attributes, such as faces, occurs in Grade 2. (2.G.1)

##### Indicator {{'1b' | indicatorName}}

Materials give all students extensive work with grade-level problems to meet the full intent of grade-level standards.

The materials reviewed for Reveal Math Kindergarten meet expectations for giving all students extensive work with grade-level problems to meet the full intent of grade-level standards. Within the materials, all standards are represented, and most meet the full intent of the grade-level standard. However, the materials provide limited opportunities for all students to engage in extensive work with grade-level problems to meet the full intent of standard K.OA.4.

Examples where the materials engage all students in extensive work with grade-level problems to meet the full intent of the standard include:

• In Lesson 3-8, Compare Objects in Groups, Differentiate, Build Proficiency, Digital Additional Practice Book: Compare Objects in Groups, Exercise 4, “How can you draw to show equal groups?” Students draw any size group of no more than 10 objects to demonstrate understanding how equal groups are formed. This exercise engages students with the full intent of K.CC.6, identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies.

• In Lesson 6-4, Represent and Solve Addition Problems, Practice and Reflect, On My Own, Exercise 2, “Use counters or drawings to show one way to solve the problem. Then write an equation to match. Sally has 3 kickballs. How many can she put in the red bin and how many in the green bin?” Students draw a picture to represent the problem and fill in the addends in the equation  3 = ___ + ___. This exercise engages students with the full intent of K.OA.2, solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.

• In Lesson 10-6, Decompose 18 and 19, Number Routine, Break Apart, “Tell students that they should break apart 19 in three different ways.” (16 in the digital format) Teacher prompts include, “What do we mean when we say ‘break apart’ a number? How did you break apart 19? Did anyone draw a picture? How did that help? Did anyone use ten-frames and counters? Show us how you used those tools.” Decomposing and composing exercises throughout Unit 10 address the full intent of  K.NBT.1, compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones, and provide extensive work with grade-level problems.

• In Lesson 12-5, Count to Find Out How Many, Differentiate, Build Proficiency, Game Station: Which Number Comes Next Race, “Directions: Decide who will go first. When it is your turn, pick a card. Count by ones. Say which number comes next. The answer keeper checks your answer with the answer key. If you are correct, move your game piece the number of spaces shown on the card. If you are not correct, stay on your space. Now it is the next player’s turn. The first player to reach the Finish line wins the game.” This engages students with K.CC.2, count forward beginning from a given number within the known sequence (instead of having to begin at 1).

• Lesson 13-2, Build and Draw 2-Dimensional Shapes, Practice & Reflect, On My Own,  Exercise 1, students are shown a circle. “How can you draw a circle? Trace the circle. Then draw a circle.” Exercise 2, students are shown a square. “How can you draw a square? Trace the square. Then draw a square.” Exercise 3, students are shown a hexagon. “How can you draw a hexagon? Trace the hexagon. Then draw a hexagon.” All of these exercises provide extensive work with K.G.5, model shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.

• In Lesson 14-3, Compare Heights, Launch, Notice and Wonder, students compare measurable attributes of two objects when provided with images of two different sized plants, “How are they the same? How are they different? Teaching Tip: If students mention attributes such as the color or type of plants, encourage them to begin thinking about height comparison by asking, What can you say about the size of the plants?” This exercise engages students with the full intent of standard K.MD.2, directly compare two objects with a measurable attribute in common, to see which object  has “more of”/”less of” the attribute, and describe the difference.

#### Criterion 1.2: Coherence

Each grade’s materials are coherent and consistent with the Standards.

The materials reviewed for Reveal Math Kindergarten meet expectations for coherence. The materials: address the major clusters of the grade, have supporting content connected to major work, make connections between clusters and domains, and have content from prior and future grades connected to grade-level work.

##### Indicator {{'1c' | indicatorName}}

When implemented as designed, the majority of the materials address the major clusters of each grade.

The materials reviewed for Reveal Math Kindergarten meet expectations that, when implemented as designed, the majority of the materials address the major clusters of each grade.

Within the materials, at least 65% of instructional time addresses the major work of the grade, including supporting work connected to major work. For example:

• There are 14 Units, of which 12.5 address major work, or supporting work connected to major work of the grade, approximately 89%.

• There are 88 lessons, of which 77 address major work, or supporting work connected to major work, approximately 88%.

• There are 150 days of instruction, 131 of which address major work, or supporting work connected to major work, approximately 87%.

The materials contained discrepancies regarding the number of days per unit, and guidance was not given as to how those days were accounted for, therefore, a lesson level analysis is most representative of the materials. As a result, approximately 88% of the instructional materials focus on major work of the grade.

##### Indicator {{'1d' | indicatorName}}

Supporting content enhances focus and coherence simultaneously by engaging students in the major work of the grade.

The materials reviewed for Reveal Math Kindergarten meet expectations that supporting content enhances focus and coherence simultaneously by engaging students in the major work of the grade. Standards K.G.5 and K.G.6 are not always connected to major work of the grade, but the separation is mathematically reasonable.

Examples of supporting work engaging simultaneously with major work of the grade, when appropriate include:

• In Lesson 4-4, Launch, Which Doesn’t Belong, Pose Purposeful Questions, the supporting work of K.MD.3 classify objects into given categories, connects to the major work of K.CC.1, count to 100 by ones and tens, and K.CC.5, count to answer “how many?” questions, as students count the objects in each category. “How are the groups the same? How are the groups different? Which group doesn’t belong? How can you use color to describe the groups? How can you use shape to describe the groups? How can you use size to describe the groups? How can you use numbers to describe the groups?” (5 purple crayons, 5 yellow pencils, 3 purple markers, 5 purple flowers)

• In Lesson 5-3, Hexagons, Practice & Reflect, On My Own, Exercise 3, the materials connect the supporting work of K.G.2, correctly name shapes regardless of their orientations or overall size, to the major work of K.CC.5, count to answer “how many?” questions, as students count the number of sides in a given shape. “Which shapes have 6 sides? Circle the shapes with 6 sides.”

• In Lesson 11-2, Cubes, Practice & Reflect, On My Own, Exercise 5, Extend Your Thinking, connects the supporting work of K.G.4, analyze and compare two- and three-dimensional shapes, to the major work of K.CC.5, count to answer “how many?” questions, as students count the number of faces on a cube and circle the correct number when provided with three numerals. “How many faces does a cube have? Circle the number of faces.” [6]

• In Lesson 13-3, Compose 2-Dimensional Shapes, Differentiate, Extended Thinking, Differentiation Resource Book, Exercise 1, the supporting work of K.G.6, compose simple shapes to form larger shapes, connects to the major work of K.CC.3, write numbers from 0 to 20, as students count to find the number of triangles that make up the hexagon. “How many triangles is this shape made of?” Students count the triangles and write the number “6” on the blank below the hexagon.

• In Lesson 13-4, Compare and Contrast 3-Dimensional Shapes, Differentiate, Reinforce Understanding, Differentiation Resource Book, Exercise 1, the supporting work of K.G.4, analyze and compare two- and three-dimensional shapes, connects to the major work of K.CC.6, identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, when they compare shapes based on defining attributes. “How can you compare the shapes? Put an X on the shape that is different.”

##### Indicator {{'1e' | indicatorName}}

Materials include problems and activities that serve to connect two or more clusters in a domain or two or more domains in a grade.

The materials reviewed for Reveal Math Kindergarten meet expectations for including problems and activities that serve to connect two or more clusters in a domain, or two or more domains in a grade. The materials contain connections from supporting work to supporting work, and connections from major work to major work throughout the grade-level materials when appropriate.

Connections between major clusters or domains include:

• In Lesson 2-9, Compare Numbers to 5, Differentiate, Build Proficiency, Digital Additional Practice Book: Compare Numbers to 5, Exercise 2, connects the major work of K.CC.C, compare numbers, to the major work of K.CC.B, count to tell the number of objects, as students determine which digit is less, then draw that number of objects. “Which number is less? [3 or 1] Draw objects to show each number. Circle the number that is less.”

• In Lesson 3-11, Write Numbers to 6, Practice & Reflect, On My Own, Exercise 4, connects the major work of K.CC.B, count to tell the number of objects, to K.CC.A, know number names and the count sequence, as students count the number of objects shown and write the number to show how many. “How many shovels? Write the number.”

Then write an equation to match. Two soccer balls and 4 volleyballs are on the shelf. How many balls are on the shelf?

• In Lesson 8-4, Ways to Decompose 6 and 7, Practice & Reflect, On My Own, Exercise 1, connects the major work of K.OA.A, understand addition as putting together and adding to, and understand subtraction as taking apart and taking from, to the major work of K.CC.B, count to tell the number of objects, as students decompose a number and write an equation. Exercise 1, students are shown six soccer balls in a row, “How can you decompose 6? Circle groups to show a way to decompose 6. Write the equation to match.  ____ = ____ + ____.”

• In Lesson 9-3, Decompose 11, 12, and 13, Differentiate, Build Proficiency, Digital Additional Practice Book: Decompose 11, 12, and 13, Exercise 1, connects the major work of K.NBT.A, work with numbers 11-19 to gain foundations for place value, to the major work of K.CC.A, know number names and the count sequence, as students decompose a number of objects and write an equation. Exercise 1, students are shown a picture of 11 flowers, “How can you decompose 11? Circle groups to decompose 11 into ten ones and some more ones. Write the equation to match.  11= ____ + ____.”

• In Lesson 10-5, Make 18 and 19, Practice & Reflect, On My Own, Exercise 4, Error Analysis, connects the major cluster of K.NBT.A, work with numbers 11-19 to gain foundations for place value, to the major cluster of K.OA.A, understand addition as putting together and adding to, and understand subtraction as taking apart and taking from, as students compose the number 18 from a group of 10 ones and some more. “There are 18 scissors. Jill says the missing number in the equation is 8. Mandy says the missing number is 9. Complete the equation to show who is correct.” A picture of 2 rows of 9 scissors each is shown. The equation is “10 + __ = 18.”

Connections between supporting clusters or domains include:

• In Lesson 4-1, Alike and Different, Launch, Notice & Wonder, Pose Purposeful Questions, connects the supporting work of K.MD.A, describe and compare measurable attributes, to the supporting work of K.MD.B, classify objects and count the number of objects in each category, as students are shown an image of different sizes and types of writing utensils and are asked to describe similarities and differences within the object set. “Think of ways that two of the objects are the same. How are they the same? How are they different from the other objects? What is the same about the objects? What is one object we could add that would be the same as all the objects shown?”

• In Lesson 4-2, Sort Objects Into Groups, Practice & Reflect, On My Own, Exercise 3, Extend Your Thinking, connects the supporting work of K.MD.B, classify objects and count the number of objects in each category, to the supporting work of K.G.A, identify and describe shapes, as students sort two dimensional shapes and identify how they sorted them. Students are shown 1 yellow triangle, 1 purple circle, 1 blue triangle, 2 blue squares, 1 purple triangle, and 1 yellow circle. “How can you sort the shapes? Draw lines to the bins. Draw on the bins to show how you sorted.” Reflect, “How are the objects sorted?”

• In Lesson 13-1, Compare & Contrast 2-Dimensional Shapes, Math Probe, Exercises 1-2, connect the supporting work of K.G.B, analyze, compare, create, and compose shapes, to the supporting work of K.MD.A, describe and compare measurable attributes, as students use defining attributes to determine which shape is not like the others. “Circle the shape that is not like the others. Tell or show why.” Exercise 1 shows three different triangles and one quadrilateral. Exercise 2 shows three quadrilaterals and one triangle.

Content from future grades is identified and related to grade-level work, and materials relate grade-level concepts explicitly to prior knowledge from earlier grades.

The materials reviewed for Reveal Math Kindergarten meet expectations that content from future grades is identified and related to grade-level work, and the instructional materials relate grade-level concepts explicitly to prior knowledge from earlier grades. As this is Kindergarten, it is mathematically reasonable that there are no connections to a previous grade and that standards build conceptually throughout the year.

Content from future grades is identified within the chapters, units, and lessons; and is connected to grade-level work. Examples include:

• In Lesson 3-1, Count 6 and 7, Coherence, Now, includes K.CC.4, understand the relationship between numbers and quantities; connect counting to cardinality. “Students count objects to 7 and show the quantities using manipulatives or representations.” In Next, “Students count objects up to 19 (Unit 10). Students count to 120 (Grade 1).” 1.NBT.1, count to 120, starting at any number less than 120.

• In Unit 4, Sort, Classify, and Count Objects, Coherence, What Students Are Learning, includes K.MD.3, classify objects into given categories; count the number of objects in each category and sort the categories by count. “Students count to determine how many objects are in a group, understanding that the last number said represents the total number of objects, and sort groups according to the number of objects.” In What Students Will Learn, “In Grade 1, students organize data into groups of up to three categories and ask and answer questions about the reasons for their groupings.” 1.MD.4, organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.

• In Lesson 7-4, Represent and Solve Subtraction Problems, Coherence, Now, includes  K.OA.1, represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations, and K.OA.2, solve addition and subtraction word problems, and add and subtract within 10. “Students apply their understanding of subtraction to represent and solve problems.” In Next, “Students will solve subtraction problems when the total, both parts, and one part part is unknown (Grade 1).” 1.OA.1, use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions.

• In Lesson 12-3, Count by 10’s to 100, Coherence, Now, includes  K.CC.1, count to 100 by ones and tens. “Students apply their understanding of counting to count by 10s to 100. Students describe patterns when counting by 10s to 100.” In Next, “Students count from any number to 100 (Unit 12.). Students explore counting patterns to 120 (Grade 1).” K.CC.2, count forward beginning from a given number within the known sequence, and 1.NBT.1, count to 120, starting at any number less than 120.

Examples where the instructional materials relate grade-level concepts explicitly to prior learning include:

• In Lesson 8-8, Ways to Decompose 10, Coherence, Now, includes K.OA.3, decompose numbers less than or equal to 10 into pairs in more than one way. “Students apply their understanding of decomposing numbers to decompose 10 in different ways. Students explain how to decompose 10 in different ways.” In Previous, “Students represented and solved subtraction problems (Unit 7). Students decomposed 8 and 9.” K.OA.1, represent addition and K.NBT.1, compose and decompose numbers from 11 to 19 into ten ones and some further ones. “Students write numbers from 16 to 19. Students represent numbers from 16 to 19. Students compose and decompose numbers from 16 to 19.” In What Students Have Learned, “Students learned how to write and read numbers from 11 to 15. (Unit 9) Students learned how to represent numbers from 11 to 15. (Unit 9) students learned how to compose and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations, and K.OA.2, solve addition and subtraction word problems, and add and subtract within 10.

• In Lesson 9-1, Represent 11, 12, and 13, Coherence, Now, includes K.CC.3, write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20. “Students apply their understanding of numbers to count, read, and represent 11, 12, and 13.” In Previous,   “Students counted and represented numbers to 10 (Unit 3).”

• In Unit 10, Numbers 16 to 19, Coherence, What Students Are Learning, includes K.CC.3, write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20, and decompose numbers from 11 to 15. (Unit 9)”

• In Lesson 13-6, Describe 3-Dimensional Shapes in the World, Coherence, Now, includes K.G.1, describe objects in the environment using names of shapes, and describe the relative positions of these objects. “Students identify and describe 3-dimensional shapes in a real- world context.” In Previous, “Students described objects in their environment using names of shapes (Unit 11).” K.G.2, correctly name shapes regardless of their orientations or overall size.

In order to foster coherence between grades, materials can be completed within a regular school year with little to no modification.

The materials reviewed for Reveal Math Kindergarten foster coherence between grades and can be completed within a regular school year with little to no modification.

There are three places within the materials that identify pacing for Kindergarten: each Unit Planner of the Teacher Edition; Digital Teacher Center, Program Overview, Learning & Support Resources, Implementation Guide, Pacing; and Digital Teacher Center, Program Resources, Course Materials, Pacing Guide. These three sources contain discrepancies in the number of days per unit.

In the Pacing Guide, the Program Table of Contents: Kindergarten, identifies that the instructional materials can be completed in 150 days. For example:

• There are 14 instructional units with 88 days of lessons.

• Each unit includes a Unit Opener: Ignite activity and Units 2-14 have a Readiness Diagnostic for 14 additional days.

• There is a Unit Assessment and Performance Task for each unit with the exception of Unit 1, for 13 days.

• The materials include Benchmark Assessments (3), and a Summative Assessment, for a total of 4 days.

• Each Unit contains a Unit Review and Units 2-14 contain a Math Probe, for an additional 27 days.

The components listed above account for 146 days. The materials do not give guidance on how to account for the other four days.

The materials note lessons are 60-64 minutes, and consist of five components plus a Number Routine exercise. For example:

• Number Routine: 5-7 minutes

• Launch: 5-7 minutes

• Explore & Develop: 20 minutes

• Practice & Reflect: 10 minutes

• Assess: 10 minutes

• Differentiate: 10 minutes

### Rigor & the Mathematical Practices

The materials reviewed for Reveal Math Kindergarten meet expectations for rigor and balance and practice-content connections. The materials help students develop procedural skills, fluency, and application. The materials also make meaningful connections between the Standards for Mathematical Content and the Standards for Mathematical Practice (MPs).

##### Gateway 2
Meets Expectations

#### Criterion 2.1: Rigor and Balance

Materials reflect the balances in the Standards and help students meet the Standards’ rigorous expectations, by giving appropriate attention to: developing students’ conceptual understanding; procedural skill and fluency; and engaging applications.

The materials reviewed for Reveal Math Kindergarten meet expectations for rigor. The materials develop conceptual understanding of key mathematical concepts, give attention throughout the year to procedural skill and fluency, spend sufficient time working with engaging applications of mathematics, and do not always treat the three aspects of rigor together or separately.

##### Indicator {{'2a' | indicatorName}}

Materials develop conceptual understanding of key mathematical concepts, especially where called for in specific content standards or cluster headings.

The materials reviewed for Reveal Math Kindergarten meet expectations for developing conceptual understanding of key mathematical concepts, especially where called for in specific content standards or cluster headings.

The materials develop conceptual understanding throughout the grade level, with teacher guidance, through discussion questions and conceptual problems with low computational difficulty. Examples include:

• In Lesson 3-7, Numbers to 10, Explore & Develop, Activity-Based Exploration, students draw 5 circles, then discuss, “How can you find one more?” Math is Thinking, “What does it mean to have one more?” Work Together, “How can you show each number? Draw counters to show each number.” Students represent numbers 0-10. At the conclusion of the lesson, Assess, Exit Ticket, Exercise 2, “How many carrots will there be if you add one more? Circle a number to show how many?” Students see 5 carrots and the choices “5, 6, 7, 8”. These activities support conceptual development of K.CC.4, understand the relationship between numbers and quantities; connect counting to cardinality.

• In Lesson 6-1, Represent and Solve Add To Problems, Launch, Notice & Wonder, students use Think-Pair-Share to respond to questions about the number of soccer players they see in a picture. Students see a group of 5 players standing in a goal, and another group of 2 players running towards them. “What do you see in the picture? Have you seen something like this before? What can you say about the two groups of players? Why might there be two groups of players? What do you think might be happening in the picture? Explain your thoughts to a friend.” The teacher guides the discussion towards the concept of putting two different groups together into one group to show the total number of objects. In Explore & Develop, Bring it Together, Work Together, “Use counters or drawings to represent the addition story. Then write the total. Four backpacks were on the bench. Two more backpacks were placed there. How many backpacks are on the bench now?” These activities support conceptual development of K.OA.1, represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.

• In Lesson 9-4, Represent 14 and 15, Launch, Notice & Wonder, students are shown a picture with a building with 15 windows and 15 bushes. “What groups of objects do you see? How can you find the number of windows? Bushes? What do you know about counting beyond 10 that can help you count these objects?” This exercise supports conceptual development of K.NBT.A, compose and decompose numbers from 11 to 19 into ten ones and some further ones.

The materials provide opportunities for students to independently demonstrate conceptual understanding through concrete, semi-concrete, verbal, and written representations. Examples include:

• In Lesson 3-3, Count 8 and 9, Practice & Reflect, Exercise 4, ”How many tablets? Color the counters to show how many.” Students are shown pictures of tablets with blank counters for students to color. This supports conceptual understanding of K.CC.4, understand the relationship between numbers and quantities; connect counting to cardinality.

• In Unit 6, Understand Addition, Math Probe, Exercise 1, students solve an addition word problem and circle the number that represents the answer. “Pat has 2 pet (picture of a dog) and 3 pet (picture of a cat). Circle the number of pets Pat has in all.” Answer choices include, “2, 3, 4, 5, 6, 7”. In the column to the right of the problem, students “Tell or show why” to justify their reasoning. This activity supports conceptual understanding of K.OA.1, represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.)

• In Lesson 8-7, Ways to Make 10, Explore & Develop, Activity-Based Exploration, students use ten-frames to practice composing groups of 10. “Give student-pairs a group of small objects and the Ten-Frame Teaching Resource. Have one student pick a number of objects that is less than 10 and place them on the ten-frame. Ask the other student to find the number of objects needed to make 10 and place those on the ten-frame. Have students repeat the activity, trading roles each time. Ask them to record equations that represent each of their groupings of 10.” Activity Debrief, “Invite student pairs to share one example of a grouping of 10 they made. Have them explain how the number in their equation represent the numbers of objects they used.” Practice & Reflect, On My Own, Reflect, students are shown a ten frame with 4 red counters and 6 yellow counters. “What is a different way to make 10 than what is shown?”  These activities support conceptual understanding of K.OA.4, for any number from 1 to 9, find the number that makes 10 when added to the given number.

• In Lesson 10-2, Make 16 and 17, Practice & Reflect, On My Own, Exercise 2, “How can you make 16? Draw counters to show a group of ten ones and some more ones. Complete the equation to match.” Students are given two ten frames to draw their counters. This activity supports conceptual understanding of K.NBT.1, compose and decompose numbers from 11 to 19 into ten ones and some further ones.

Materials give attention throughout the year to individual standards that set an expectation for procedural skill and fluency.

The materials reviewed for Reveal Math Kindergarten meet expectations for giving attention throughout the year to individual standards that set an expectation of procedural skill and fluency.

The materials develop procedural skill and fluency throughout the grade with teacher guidance, within standards and clusters that specifically relate to procedural skill and fluency, and build fluency from conceptual understanding. Examples include:

• Fluency Practice exercises are provided at the end of each unit. Each Fluency Practice includes: Fluency Strategy, Fluency Flash, Fluency Check, and Fluency Talk. “Fluency practice helps students develop procedural fluency, that is, the ‘ability to apply procedures accurately, efficiently, and flexibly.’ Because there is no expectation of speed, students should not be timed when completing the practice activity.” Fluency Practice exercises in Kindergarten progress toward K.OA.5, fluently add and subtract within 5.

• In Lesson 6-5, Represent and Solve More Addition Problems, Practice & Reflect, On My Own, Exercise 1, “Use counters or drawings to represent the problem. Then write an equation to match. Four balls were in the basket. Three more balls were tossed in the basket. How many balls are in the basket now? ____ + ____ =  ____.” Students build fluency from conceptual understanding as they use counters or drawings to represent a problem. This exercise supports the development of procedural skill and fluency of K.OA.1, represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.

• In Unit 6, Understand Addition, Fluency Practice, Fluency Strategy, “You can count objects up to 10 in different arrangements.” Students see 3 groups of paper clips arranged in different ways. Group 1 has 10 paper clips, group 2 has 6 paper clips, group 3 has 8 paper clips. Exercise 1, “How many dog bones?

Materials are designed so that teachers and students spend sufficient time working with engaging applications of the mathematics.

The materials reviewed for Reveal Math Kindergarten meet expectations for being designed so that teachers and students spend sufficient time working with engaging applications of the mathematics. Additionally, the materials provide students with the opportunity to independently demonstrate multiple routine and non-routine applications of the mathematics throughout the grade level.

The materials provide specific opportunities within each unit for students to engage with both routine and non-routine application problems. In the Digital Teacher Center, Program Overview: Learning & Support Resources, Implementation Guide, Focus, Coherence, Rigor, Application, “Students encounter real-world problems throughout each lesson. The On My Own exercises include rich, application-based question types, such as ‘Find the Error’ and ‘Extend Thinking.’ Daily differentiation provides opportunities for application through the Application Station Cards, STEM Adventures, and WebSketch Explorations. The unit performance task found in the Student Edition offers another opportunity for students to solve non-routine application problems.”

The materials develop application throughout the grade as students solve routine problems in a variety of contexts and model the contexts mathematically within standards and clusters that specifically relate to application, both dependently and independently. Examples include:

• In Lesson 5-5, Position of 2-Dimensional Shapes, Launch, “Students notice different real- world 2-dimensional shapes and their locations by looking at a picture composed of different shapes.” Notice & Wonder, “What do you notice? What do you wonder?” In the Teaching Tip, teachers “may give clues by asking questions using the terms above, behind, below, inside, in front of, or next to. Although students are not expected to use these terms during the Notice and Wonder, using them yourself will introduce students to the terms.” This exercise allows students to develop and apply mathematics of K.G.1, describe objects in the environment using names of shapes, and describe the relative positions of these objects. In Practice & Reflect, On My Own, Exercise 3, Error Analysis, “Julian says the object above the clipboard is shaped like a triangle. Is he correct? Circle the object that is above the clipboard. Describe its shape.” This exercise allows students to independently apply the mathematics of K.G.1, describe objects in the environment using names of shapes, and describe the relative positions of these objects.

• In Unit 6, Understand Addition, Performance Task, Part A, “Roman finds 7 bees on flowers.  Some are on pink flowers and some are on red flowers. How many bees can be on each type of flower? Draw to show the problem. Then write an addition equation for your drawing.” This allows students to independently apply mathematics of K.OA.2, solve addition and subtraction word problems, and add and subtract within 10.

• In Lesson 11-6, Describe Solids, Explore & Develop, Learn, “How can you use names of shapes to describe positions of objects in the classroom?” Students are shown a classroom scene with items such as round tables, chairs, a window, an aquarium, teacher desk, chalkboard, clock, etc. Pose Purposeful Questions, “Which shape do you notice first? Where is it? Is there a shape that is located at the top of the picture? The bottom? Explain.” This exercise allows students to develop and apply mathematics of K.G.1, describe objects in the environment using names of shapes, and describe the relative positions of these objects using terms such as above, below, beside, in front of, behind and next to.

The materials develop application throughout the grade as students solve non-routine problems in a variety of contexts and model the contexts mathematically within standards and clusters that specifically relate to application, both dependently and independently. Examples include:

• In Lesson 7-2, Represent and Solve Take from Problems, Explore & Develop, Activity Based Exploration, Activity Debrief, after students have used counters to model and solve teacher provided word problems, “Have groups share how they represented the word problems with counters. Encourage students to make up their own subtraction word problem and share it with the class.” This exercise allows students to develop the mathematics of K.OA.1, represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.

• In Lesson 7-4, Represent and Solve Subtraction Problems, Explore & Develop, Activity- Based Exploration, “Have one student draw 6 objects and roll the number cube. Then, have that same student cross out the number of objects based on the number he or she rolled, showing that many objects were subtracted from the original group. Ask the other student to write the subtraction equation below the drawing. Have students tell a word problem that matches the drawing and equation. Repeat using starting numbers of 7, 8, 9, and 10.” This exercise allows students to develop the mathematics of K.OA.2, solve addition and subtraction word problems, and add and subtract within 10. In Practice & Reflect, On My Own, Exercise 4, Extend Your Thinking, “Create your own subtraction story. Draw a picture to represent your story.

Have one student create a word problem using the connecting cubes such as, Lilly has 2 cubes and Bella gives her 5 more. How many cubes does Lilly have? Ask the other student to create an equation to show the problem. Have students work together to see if the equation is correct for the situation. Repeat as time allows.” In Lesson 6-4, Represent and Solve Addition Problems, Practice & Reflect, On My Own, Exercise 2, “Use counters or drawings to show one way to solve the problem. Then write an equation to match. Sally has 3 kickballs. How many can she put in the red bin and how many in the green bin.” Unit Review, Performance Task, “A paramedic has 8 bins for organizing her first-aid supplies. Some bins are orange. Some are purple. How many of each color bin could the paramedic have?  Part A Color the bins to show one way. Part B Color the bins a different way. Part C How many bins does the paramedic have in all? Write an equation to match one way you colored the bins.” Unit 6 balances the three aspects of rigor for K.OA.2, solve addition and subtraction word problems, and add and subtract within 10.

• In Lesson 7-3, Represent and Solve More Take From Problems, Practice & Reflect, On My Own, Exercise 5, Extend Your Thinking, “Write numbers and trace symbols to complete the equation. Anthony threw the bowling ball and 4 pins were still standing. How many pins did Anthony knock down?” Students see six bowling pins and the equation 6 - ___ = 4. This exercise provides an opportunity for students to develop procedural skill and fluency and conceptual understanding, while applying the mathematics of K.OA.2, solve addition and subtraction word problems, and add and subtract within 10.

• In Lesson 11-3, Spheres, Explore & Develop, Activity-Based Exploration, students sort wooden geometric solids and classroom objects. “Have students lay all objects in the middle of the table. Ask students to take turns choosing the spheres and the objects shaped like spheres. Once all of the spheres are chosen, ask students how they are alike. Discuss that spheres have a rounded surface, no flat faces, and can roll. Ask students to explain why the other shapes are not spheres or shaped like spheres. Discuss the attributes of the other objects and how they are different than the attributes of a sphere.” Math is...Generalizations, “How are all spheres the same?” Practice & Reflect, On My Own, Exercise 3, “Which shapes are spheres? Circle all the spheres.” Students see several three dimensional shapes (sphere, cube and cylinder) of different sizes and colors.

• In Lesson 4-3, Count Objects in Groups, Explore & Develop, Work Together, students attend to precision as they count and write the number of birds in each group. “Common Misconception: Students may still be struggling to count objects accurately. Remind them to say only one number as they touch each object, and not to count one object twice. Also remind them that the last number they say is the number of objects in the group.” Students see two bird cages. One bird cage has 5 blue birds in the cage. The other bird cage has 4 blue birds in the cage. “How many birds in each group? Write a number to show how many.”

• In Lesson 5-3, Hexagons, Practice & Reflect, On My Own, Exercise 3, students attend to the precision of mathematics as they count the sides of shapes to determine which shapes have 6 sides, “Which shapes have 6 sides? Circle the shapes with 6 sides.”

• In Lesson 7-2, Represent and Solve Take From Problems, Explore & Develop, Activity-Based Exploration, students attend to precision as they count correctly to subtract, “Distribute one set of counters to each pair or small group of students. Read various take from word problems aloud to the students. For example, ‘Maria has 8 strawberries. She gives 3 strawberries to her sister. How many strawberries does Maria have now?’ Have students use their counters to model each situation and find the difference. Repeat as time allows.” Support Productive Struggle, “How can you use counters to show a take from problem? How do you know how many counters you need to start with? How do you know how many counters to take from the group?” Math is...Precision, “Why is it important to count correctly when you subtract?”

• In Lesson 14-2, Compare Lengths, Practice & Reflect, On My Own, Exercise 3, students attend to precision as they compare the lengths of provided objects and identify which object is longer. “Which is longer? Circle the longer object. Underline the objects if they are the same length.”

Specialized language stands alone with vocabulary presentations in each lesson. When MP6 is identified for a lesson, MP6 specifically refers to precision with mathematics. Examples where the instructional materials attend to the specialized language of mathematics, including guidance for teachers to engage students in MP6 include:

• In Unit 5, 2-Dimensional Shapes, Unit Overview, Math Practices and Processes, Attend to Precision, “Attending to precision is important in geometry. Describing attributes and positions of shapes accurately provides an opportunity to introduce students to description words and to strengthen their vocabulary. Students should be given many opportunities to use these words throughout this and future units. As students become more proficient in using these words, encourage them to use as many as possible when describing a shape, including words that describe the shape’s position. Some suggestions for building precision include:

• Students provide detailed descriptions of shapes to partners who try to draw the shape.

• Students discuss the similarities and differences of two or more shapes.

• Students describe a shape in the classroom, adding more detail until a classmate is able to identify the shape.

• Students create a word wall of different description words that can be used to describe shapes.”

• In Lesson 7-2, Represent and Solve Take From Problems, Explore & Develop, Language of Math, “The term subtract is a verb. Talk to students about how to subtract also means to find the difference. Encourage students to use subtract or difference in a sentence as they discuss it with other students.” This guidance for teachers engages students in the full intent of MP6, attending to the specialized language of mathematics.

• In Lesson 13-6, Describe 3-Dimensional Shapes in the World, Explore & Develop, Activity- Based Exploration, students attend to the specialized language of mathematics as they discuss the attributes of geometric solids. Directions, “Discuss the attributes of each wooden geometric solid. Remind students about the faces, bases, apex, and vertices. Also, discuss if the shapes can roll or stack. Show the real-world objects and discuss what they are shaped like. Then, ask students to think of other objects that they have seen at home, at school, on the playground, in the store, etc. that are shaped like 3-dimensional shapes that they know. After naming a shape, discuss how to describe its relative position.”

• In Unit 14, Compare Measurable Attributes, Unit Review, Performance Task, Reflect, students attend to the specialized language of mathematics as they compare a small pot of water to a large pot of water, “How can you compare objects? Explain how you can compare the length, weight, height, and capacity of the objects.”

Materials support the intentional development of MP7: Look for and make use of structure; and MP8: Look for and express regularity in repeated reasoning, for students, in connection to the grade-level content standards, as expected by the mathematical practice standards.

The materials reviewed for Reveal Math Kindergarten meet expectations for supporting the intentional development of MP7: Look for and make use of structure; and MP8: Look for and express regularity in repeated reasoning, for students, in connection to grade-level content standards, as expected by the mathematical practice standards.

Each Unit Overview identifies one mathematical practice that is prevalent in the unit and gives an overview of its use within the unit. In the Standards section of each lesson, mathematical practices for the lesson are also identified; however, the mathematical practice is labeled MPP Look for and make use of structure, rather than MP7: Look for and make use of structure; and MP8: Look for and express regularity in repeated reasoning. Additionally, the math practices are not identified within the lesson sections, therefore leaving where they are specifically addressed up for interpretation and possible misidentification. However, upon review, it was found that the materials provide additional opportunities for students to engage in the full intent of MP8 that were not identified for teachers.

Examples of intentional development of students looking for and making use of structure, to meet its full intent in connection to grade-level content, including guidance for teachers to engage students in MP7 include:

• In Unit 2, Numbers to 5, Unit Overview, Math Practices and Processes, Look for and Make Use of Structure, “This unit introduces students to numerals 0 through 5 and makes the connection between numerals and number names. Students will have opportunities to count different objects, which will help them connect a number name with an amount. Students will also see that the arrangement of the objects does not change the number in the group. In addition, students will use the structure of matching objects in two groups to determine if the two groups are equal or if one is greater. Some suggestions to help students identify these connections and structure are:

• Show representations of numbers using different objects and in differing arrangements. Have students identify how the representations are connected and how they relate back to the number being discussed.

• Allow students time to represent each number using different objects.  Students can then discuss how the representations are alike and different.

• Encourage students to use a strategy such as matching when comparing numbers, and have them justify their answer.”

• In Lesson 2-7, Equal Groups to 5, Practice & Reflect, On My Own, Exercise 2, students look for structure as they draw lines to match objects to determine if groups are equal. “Are the two groups equal? Circle the groups if they are equal. Draw an X on the groups if they are not equal.”

• In Lesson 4-4, Describe Groups of Objects, Explore & Develop, Activity-Based Exploration, teachers engage students to look for and explain structures as they use a 3-part sorting mat to have students sort, count, and compare the number of pattern blocks in the groups. “Directions: Provide each student or group of students with a collection of pattern blocks and a 3-Part Sorting Mat Teaching Resource. Each collection of blocks should contain only 3 different shapes with no more than 10 of each shape. Have students sort the pattern blocks into groups. Then have them count the number of objects in each group. Ask students to compare the number of objects in each group, encouraging them to use comparison terms such as more and fewer. Math is ... Structure: What can you look at to describe and compare sorted groups?”

• In Lesson 13-1, Compare and Contrast 2-Dimensional Shapes, Practice & Reflect, On My Own, Reflect, students look for structure by looking at the number of sides and vertices (corners) to make generalizations to describe and compare shapes, “How can you compare the shapes?” Students see 5 different colored shapes in row:  hexagon, triangle, circle, triangle, square.

Examples of intentional development of students looking for and expressing regularity in repeated reasoning, including guidance for teachers to engage students in MP8 include:

• In Lesson 4-2, Sort Objects into Groups, Explore & Develop, Guided Exploration, students use regularity in repeated reasoning to explain how objects are sorted. “Students apply the skills they used to describe attributes of objects to sorting objects by attribute. Students will become aware that objects can be sorted according to more than one attribute, which helps them develop an understanding that multiple solution strategies are acceptable in mathematics. Discuss that the group of buttons can be sorted in different ways. Guide students in seeing that some of the ways that the buttons could be sorted are by size, color, and shape.” Digital Guided Exploration, Presentation slide slide 2.4, students are shown 4 heart shaped buttons, 5 small buttons, and 3 red buttons, Math is … Generalizations, “How can you describe sorted groups of objects?”

• In Lesson 5-2, Squares and Rectangles, Explore & Develop, Activity-Based Exploration, teachers engage students with MP8 as they support them in sorting squares and rectangles of different sizes and colors and make generalizations about the shapes. “Directions: Students work in small groups. Provide each group with objects shaped like squares and rectangles of different sizes and colors. Groups should sort the shapes according to a common attribute.” Math is...Generalizations, “How are all the rectangles the same? How are all squares the same? Why are all squares also rectangles? Explain whether or not all rectangles are squares.” Within the Practice & Reflect, On My Own, Reflect, students look for and use repeated reasoning to explain how they know a shape is a rectangle, “How do you know if a shape is a rectangle?” Students see a row of 5 different 2-dimensional shapes: rectangle, circle, rectangle, triangle, rectangle.

• In Lesson 7-3, Represent and Solve More Take From Problems, Practice & Reflect, Reflect, students use repeated reasoning as they create an equation to represent a subtraction situation, “How can you use an equation to represent subtraction?” Students see 5 shirts with 3 crossed out.

Materials contain adult-level explanations and examples of the more complex grade-level/course-level concepts and concepts beyond the current course so that teachers can improve their own knowledge of the subject.

The materials reviewed for Reveal Math Kindergarten partially meet expectations for containing adult-level explanations and examples of the more complex grade/course-level concepts and concepts beyond the current course so that teachers can improve their own knowledge of the subject. The materials provide opportunities for teachers to grow their knowledge of grade level concepts, but the materials do not contain adult-level explanations and examples of concepts beyond the current course so that teachers can improve their own knowledge of the subject.

The Teacher Edition and Digital Teacher Center contain clear supports to develop a teacher’s understanding of advanced grade level concepts. Expert videos give insight into the mathematics as well as the sense-making routines of the course. Teachers can prepare for a unit by utilizing several supports in the Unit Overview that highlight specific mathematical concepts such as coherence. These supports provide the teacher a quick snapshot of how the math concepts for that unit fit within the scope of current and  future lessons, units, and grades. Rigor, Effective Teaching Practices, Math Practices and Processes, and the Language of Math, don’t define vocabulary, but rather list which lesson it will be used.

The Digital Teacher Center provides the teacher with Expert Insight videos to help develop the mathematics they need for this course. Examples include:

• In Unit 4, Sort, Classify and Count Objects, Unit Resources, Expert Insights: Sort, Classify and Count Objects, “This professional learning video features Reveal Math specialist, Roxanne Laird, explaining what students will learn during this unit, sharing insights to help you prepare to teach, and offering tips for supporting students' success.” For example, “Students may initially struggle with counting and comparing sorted groups. To help students develop this idea, have them sort engaging hands-on manipulatives such as colorful buttons or shells. Then have them use one-to-one correspondence to count the number of objects in each group. Finally, have students compare the groups. Ask, ‘Which group has more?’”

• In Unit 7, Understand Subtraction, Unit Resources, Expert Insights: Subtraction, “This professional learning video features Reveal Math author, Susie Katt, explaining what students will learn during this unit, sharing insights to help you prepare to teach, and offering tips for supporting students' success.” For example, “In this unit, students will also be introduced to another symbol, the minus sign. Often, young students will call this symbol the take away sign. Be intentional with your language. Use ‘minus sign’ when referring to this symbol. Not only is this mathematically precise, it will also help eliminate potential confusion when students explore comparison subtraction in later grades.”

Inclusions such as Discussion Supports, Key Takeaways, Common Misconceptions, Common Error, and Language of Math provide insight to the specific mathematical concepts of the lesson. Examples include:

• In Lesson 6-2, Represent and Solve More Add to Problems, Explore & Develop, Bring it Together, Language of Math, teachers are provided with detailed information to guide students in understanding the difference between to add and the sum, “Talk to students about the difference between to add which is the action of adding, and the sum or the total which is the answer to an addition problem.”

• In Lesson 3-10, Write Numbers to 3, Explore & Develop, Bring it Together, Common Error, “Students may make reversals or other errors while forming numbers. Point out these reversals, but continue to emphasize correct number usage rather than formation.”

Materials include standards correlation information that explains the role of the standards in the context of the overall series.

The materials reviewed for Reveal Math Kindergarten meet expectations for including standards correlation information that explains the role of the standards in the context of the overall series.

Correlation information is present for the mathematics standards addressed throughout the grade level. Examples of how individual units, lessons, or activities throughout the series are correlated to the CCSSM include:

• In the Digital Teacher Center, Program Overview: Learning & Support Resources, Implementation Guide, Correlations, identifies the standards included in each lesson. This guide also indicates whether the standards are considered major, supporting, or additional standards.

• Each Unit Planner includes a pacing guide identifying the standards that will be addressed in each lesson.

• In Lesson 3-8, Compare Objects in Groups, the materials identify standard K.CC.6, identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies. The lesson also identifies MP2, reason abstractly and quantitatively.

• In Lesson 7-2, Represent and Solve Take From Problems, the materials identify standard K.OA.1, represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations. The lesson also identifies MP6, attend to precision.

The teacher materials contain explanations of the role of the specific grade-level mathematics, including prior and future content connections. Examples include:

• The Unit Overview includes the section, Coherence, identifying What Students Have Learned, What Students Are Learning, What Students Will Learn. In Unit 4, Sort, Classify, and Count Objects, What Students Have Learned, “Students may be familiar with simple words that describe objects, notable color words, shape words, and size words (red, round, small). Students may know how to name numbers through ten or more. They may also have learned that each object in a group needs its own number when the group is being counted.” What Students Are Learning, “Students recognize attributes based on color, shape, and size and use these attributes to describe objects. Students create groups of objects based on the objects’ attributes. Students count to determine how many objects are in a group, understanding that the last number said represents the total number of objects, and sort groups according to the number of objects.” What Students Will Learn, “In Grade 1, students organize data into groups of up to three categories and ask and answer questions about the reasons for their groupings. In Unit 12, students expand on their understanding of counting to answer how many? questions about up to 20 objects arranged in a regular configuration, or up to 10 scattered objects. Given a number from 1-20, students learn to count out that many objects.”

• Each lesson begins by listing the standards covered within the lesson, indicates whether the standard is a major, supporting or additional standard, and identifies the Standards for Mathematical Practice. Each lesson overview contains a coherence section that provides connections to prior and future work. In Lesson 9-3, Decompose 11, 12, 13, Coherence, Previous, “Students decomposed numbers to 10 (Unit 8). Students composed 11, 12, and 13 into ten ones and some more ones (Unit 9).” Now, “Students apply their understanding of decomposing numbers to decompose 11, 12, and 13 into ten ones and some more ones.” Next, “Students make and decompose 14 and 15 (Unit 9). Students use place value to make numbers to 19 (Grade 1).”

Materials provide explanations of the instructional approaches of the program and identification of the research-based strategies.

The materials reviewed for Reveal Math Kindergarten meet expectations for providing explanations of the instructional approaches of the program and identification of the research-based strategies.

The materials explain the instructional approaches of the program. Examples include:

• Digital Teacher Center, Program Overview: Learning & Support Resources, Teacher Welcome Letter Template specifies “Reveal Math, a balanced elementary math program, develops the problem solvers of tomorrow by incorporating both inquiry-focused and teacher-guided instructional strategies within each lesson.”

• Teacher Guide, Volume 1, Welcome to Reveal Math, the overall organization of the math curriculum has five goals:

• "The lesson model offers two instructional options for each lesson: a guided exploration that is teacher-guided and an activity-based exploration that has students exploring concepts through small group activities and drawing generalizations and understanding from the activities.

• The lesson model incorporates an initial sense-making activity that builds students’ proficiency with problem solving. By focusing systematically on sense-making, students develop and refine not just their observation and questioning skills, but the foundation for mathematical modeling.

• Both instructional options focus on fostering mathematical language and rich mathematical discourse by including probing questions and prompts.

• Unit builds student agency for mathematics. Students consider their strengths in mathematics, the thinking habits of proficient “doers of mathematics,” and the classroom norms that are important to a productive learning environment.

• The scope and sequence reflects the learning progressions recommended by leading mathematicians and mathematics educators. It emphasizes developing deep understanding of the grade-level concepts and fluency with skills, while also providing rich opportunities to apply concepts to solve problems."

The Implementation Guide, located in the Digital Teacher Center, further explains the instructional approaches of specific components of the program. Examples include:

• Unit Features, Unit Planner, “Provides at-a-glance information to help teachers prepare for the unit. Includes pacing: content, language, and SEL objectives; key vocabulary including math and academic terms; materials to gather; rigor focus; and standard (s).”

• Unit Features, Spark Student Curiosity Through Ignite! Activities, “Each unit opens with an Ignite! Activity, an interesting problem or puzzle that: Sparks students’ interest and curiosity, Provides only enough information to open up students’ thinking, and Motivates them to persevere through challenges involved in problem solving.”

• Instructional Model, “Reveal Math’s lesson model keeps sense-making and exploration at the heart of learning. Every lesson provides two instructional options to develop the math content and tailor the lesson to the needs and structures of the classroom.” Each lesson follows the same structure of a “Launch, Explore & Develop, Practice & Reflect, Assess and Differentiate.”

• Number Routines, in each lesson there is a highlighted number routine for teachers to engage students with. These routines “are designed to build students’ proficiency with number and number sense. They promote an efficient and flexible application of strategies to solve unknown problems…”

The Implementation Guide, located in the Digital Teacher Center, discusses some of the researched based features of the program. Examples include:

• Implementation Guide, Effective Mathematical Teaching Practices, “Reveal Math’s instructional design integrates the Effective Mathematics Teaching Practices from the National Council of Teachers of Mathematics (NCTM). These research-based teaching practices were first presented and described in NCTM’s 2014 work Principles to Action: Ensuring Mathematical Success for All.

• Implementation Guide, Social and Emotional Learning, “In addition to academic skills, schools are also a primary place for students to build social skills. When students learn to manage their emotions and behaviors and to interact productively with classmates, they are more likely to achieve academic success Research has shown that a focus on helping students develop social and emotional skills improves not just academic achievement, but students’ attitudes toward school and prosocial behaviors (Durlak et al., 2011)...”

• Implementation Guide, Support for English Learners, Lesson-level support, English Learner Scaffolds, each lesson has an “English Learner Scaffolds” section to support teachers with “scaffolded instruction to help students make meaning of math vocabulary, ideas, and concepts in context. The three levels of scaffolding within each lesson - Entering/Emerging, Developing/Expanding, and Bridging/Reaching are based on the 5 proficiency levels of the WIDA English Language Development Standards.”

• Implementation Guide, Math Language Routines, throughout the materials certain language routines are highlighted for teachers to encourage during a lesson, these routines were developed by a team of authors at Center for Assessment, Learning and Equity at Standard University and are “based on principles for the design of mathematics curricula that promote both content and language.” In the implementation guide, the material lists all eight Math Language routines and their purposes, “MLR1: Stronger and Clearer Each Time - Students revise and refine their ideas as well as their verbal or written outputs.”

• Implementation Guide, Math Probe - Formative Assessment, each unit contains a Math Probe written by Cheryl Tobey. Math Probes take time to discover what misconceptions might still exist for students. Designed to ACT, “The teacher support materials that accompany the Math Probes are designed around an ACT cycle - Analyze the Probe, Collect and Assess Student Work, and Take Action. The ACT cycle was originally developed during the creation of a set of math probes and teacher resources for a Mathematics and science Partnership Project.”

• In Unit 4, Sort, Classify, and Count Objects, Unit Assessment (Form A), Item 1 lists “Alike and Different Objects” as the Guided Support Intervention Lesson. This resource can be located in the Digital Teacher Center in the Targeted Intervention section of the Unit.

Unit Performance Tasks include a scoring rubric that evaluates student work for each section on a 2, 1, or 0 point scale. No follow-up guidance is provided for the Performance Task. For example:

• In Unit 5, 2 Dimensional Shapes, Unit Review, Performance Task, Rubric (4 Points), Part A-2 points, “2 Points: Students' work shows proficiency with identifying a circle and describing its position relative to objects in a picture. 1 Point: Students work shows developing proficiency with identifying a circle and describing its position relative to other objects. The student either correctly identifies the circle OR describes its position. 0 Points: Students work shows weak proficiency with identifying a circle and describing its position relative to other objects. The student does not correctly identify the circle OR describe its position.”

Math Probes analyze students’ misconceptions and are provided at least one time per Unit, beginning with Unit 2. In the Teacher Edition, “Authentic Student Work” samples are provided with correct student work and explanations. An “IF incorrect…, THEN the student likely…Sample Misconceptions” chart is provided to help teachers analyze student responses. A Take Action section gives teachers suggestions and resources for follow up or remediation as needed. There is a “Revisit the Probe” with discussion questions for students to review their initial answers after they are provided additional instruction, along with a Metacognitive Check for students to reflect on their own learning. For example:

Exit Tickets are provided at the end of each lesson and intended to determine the students’ understanding of the lesson concepts and provide data to inform differentiation. Each includes a Metacognitive Check allowing students to reflect on their understanding of lesson concepts on a scale of 1 to 3, with 3 being the highest confidence, and beginning in Unit 2, include an Exit Skill Tracker that lists each item’s DOK, skill, and standard. The Exit Ticket Recommendations chart provides information regarding which differentiation activity to assign based on the student’s score. For example, “If students score…Then have students do” which provides teachers information on what Differentiation activities to use such as Reinforce Understanding, Build Proficiency or Extend Thinking. For example:

• In Lesson 8-5, Exit Ticket, “If students score 2 out of 2, Then have students do Additional Practice or any of the B or E activities.” The Build Proficiency (B) activities include Practice It! Game Station, Make 8 and 9 Task Cards Workstation, and Interactive Additional Practice. The Extend Thinking (E) activities include Use It! Application Station, Make a Shaker workstation, and Websketch Exploration.

Reveal Math offers a variety of opportunities for students to demonstrate the full intent of grade-level standards and mathematical practices. While content standards and DOK levels are consistently identified for teachers in the Teacher Edition, and content standards are labeled for students in digital assessments, the standards for mathematical practice are not identified for teachers or students. It was noted that although assessment items do not clearly label the MPs, students are provided opportunities to engage with the mathematical practices.

Unit Readiness Diagnostics are given at the beginning of each unit, beginning with Unit 2. Formative assessments include; Work Together, Exit Tickets, and Math Probes. Summative assessments include; Unit Assessment Forms A and B, and Unit Performance Tasks at the end of a unit. Benchmark Assessments are administered after multiple units, and an End of the Year (Summative) Assessment is given at the end of the school year. Examples include:

• In Unit 9, Numbers 11-15, Performance Task, supports the full development of K.CC.3 (Write numbers from 0 to 20), K.NBT.1 (Compose and decompose numbers from 11 to 19 into ten ones and some further ones) and MP4 (Model with mathematics) as students demonstrate their understanding of writing and representing numbers up to 15. Stimulus, “Listen carefully. Arjun sets up a game with Penny. They are getting ready to play the game. Part A. Arjun did not finish writing the numbers on the game board. Write the missing numbers on the game board. Part B. Penny moves her marker to the number after 13. Write the number Penny moves to. Draw to show this number as 10 ones and some more ones.”

• In Lesson 12-4, Count From Any Number to 100, Assess, Exit Ticket, supports the full intent of K.CC.2 (Count forward beginning from a given number within the known sequence) and MP6 (Attend to precision). Exercise 1, “How many blocks? Count each set of blocks. Write the number that comes next.” Students are shown 5 tens and 4 ones and 5 tens and 5 ones in base ten blocks.

• In Unit 13, Analyze, Compare and Compose Shapes, Performance Task, assesses K.G.5 (Model shapes in the world by building shapes from components) and supports the full development of MP4 (Model with mathematics) as students name and draw shapes based on attributes. Part A, “Ada and Oscar each draw a shape. Ada’s shape has 4 sides. It has 2 short sides and 2 long sides. It also has 4 corners. What is Ada’s shape? Draw Ada’s shape. Oscar’s shape also has 4 sides. It has 4 corners. Oscar’s shape has 4 sides that are the same length. What is Oscar’s shape? Draw Oscar’s shape.”

• Benchmark Assessment 3, Item Analysis, Item 3, is aligned to DOK 2 and develops the full intent of K.MB.3 (Classify objects into given categories), K.G.2 (Correctly name shapes regardless of their orientations or overall size), and MP2 (Reason abstractly and quantitatively) as students identify everyday items that are shaped like circles and triangles. “Which object is a circle or a triangle? Circle the object that is shaped like a circle. Draw an x on the object that is shaped like a triangle.” Students see a triangular sign, a whole pizza cut into 10 triangular slices, and 2 square shaped interlocking pieces.
