The instructional materials reviewed for Ready Grade 4 meet the expectation for developing conceptual understanding of key mathematical concepts, especially where called for in specific content standards or cluster headings. Students use pictures, manipulatives, and models to demonstrate conceptual understanding.

The Teacher Resource Book contains a section called Concept Extension that provides teachers with additional ways to support building students’ conceptual understanding. Examples of how the Concept Extension supports teachers in building conceptual understanding include:

• Unit 1 Lesson 3 provides guidance to teachers on how to connect regrouping in addition to regrouping in subtraction, using base ten blocks. (4.NBT.4).
• Unit 2 Lesson 7 provides guidance to teachers on how to use patterns to find all the factor pairs for a number (4.OA.4).
• Unit 4 Lesson 15 provides guidance to teachers on how to use number lines to help extend student understanding of decomposing fractions (4.NF.3).

Clusters 4.NF.A, 4.NF.B, and 4.NF.C focus on understanding fractions as numbers and fraction equivalence.

• In Unit 4 Lesson 14 Compare Fractions (4.NF.2) students use note cards and divide them into thirds, fourths, fifths, and tenths to compare fractions. During this lesson, groups of students also use number lines to compare fractions.
• In Unit 4 Lesson 16 Add and Subtract Fractions (4.NF.3) students cut a piece of notebook paper into 12 equal strips and practice adding twelfths. Students use number lines to add fractions. Students divide paper plates into eighths, shade ⅝, and cut out 2 eighths using scissors to determine how much is remaining.
• In Unit 4 Lesson 20 Fractions as Tenths and Hundredths (4.NF.5) students use pennies and dimes to model tenths and hundredths.

The instructional materials reviewed for Ready Grade 4 meet the expectation for giving attention throughout the year to individual standards that set an expectation of procedural skill and fluency. The materials provide opportunities to attend to procedural skill and fluency throughout the course, including fluency of adding and subtracting within 1,000,000 (4.NBT.4).

All lessons provide an opportunity for students to use computation skills. Each lesson contains a Building Fluency section which is designed to be used twice during a lesson. The Student Practice and Problem-Solving Book contain fluency practice pages, and Math Center Activities are included in the Teacher Toolbox which include activities for both procedural skill and fluency.

• Unit 1 Lesson 3 addresses adding and subtracting whole numbers within 1,000,000 (4.NBT.4).
• Unit 1 Math in Action integrates adding and subtracting within 1,000,000 (4.NBT.4).
• In Unit 4 Lessons 16 and 17 students add fractions with like denominators and compare fractions with different numerators and denominators (4.NF.3).

iReady Door 24 Plus is a free iPad app for fact fluency practice and is only available on the Apple platform. The game includes the fluencies for Grade 4.

The instructional materials reviewed for Ready Grade 4 meet the expectation for being designed so that teachers and students spend sufficient time working with engaging applications of the mathematics without losing focus on the major work of each grade.

Opportunities to work with engaging applications are provided throughout the instructional materials. Each unit contains a Math in Action where students are exposed to non-routine problems that contain many points of entry, have more than one possible solution, integrate multiple standards, and include a Persevere on Your Own section. During guided practice Try It and independent practice Practice by Myself, students apply what they have learned to solve real-world problems. Most lessons also have an online interactive tutorial for students which features real-world applications. In addition, there are Problem Solving Connection problems where students solve multi-step word problems with whole numbers (4.OA.3), solve real world problems using addition and subtraction of fractions (4.NF.3d), and solve real world problems using multiplication of fractions (4.NF.4c). The following are examples of the applications included in the instructional materials:

• In Unit 2 Lesson 10 students are presented with multiple opportunities to solve problems posed with whole numbers using the four operations in contexts that include miles walked in a 3-week period, planting flowers in pots, and reading books.
• In Unit 4 Lesson 17 Practice & Problem Solving Book students solve real-world problems using addition and subtraction of fractions in contexts that include mixing together a fruit salad, distance traveled during a trip, and determining how much fabric is used in a costume.
• Unit 4 Lesson 20 Practice & Problem Solving Book page 214: “Mila has 100 math problems to finish this week. She solved 2/10 of the problems on Monday and 25/100 of the problems on Tuesday. Which day did she solve more problems? What fraction of the problems did she solve on Monday and Tuesday? Has she completed more than ½ her problems?”

The instructional materials reviewed for Ready Grade 4 meet the expectations for balancing the three aspects of rigor. Overall, the three aspects of rigor are not always treated together and are not always treated separately within the materials.

Each lesson contains opportunities for students to build conceptual understanding, procedural skills and fluency, and apply their learning in real-world problems. Lessons are designed so students engage with all three components of rigor at different points in the lesson. During Guided Instruction and Guided Practice, students explore alternative solution pathways to master procedural fluency. During Independent Practice, students apply the concept in real world applications where they need to use both the procedural skills and their understanding of the concept to solve problems with multiple solutions and explain/compare their solutions.

For example, in Unit 5 Lesson 24 Time and Money students explain procedures for finding elapsed time, total time, conversion between units of time, money spent/saved and conversion between units of money. Through Guided and Independent Practice, students demonstrate multiple strategies to solve time and money problems, building fluency. In Independent practice, students also demonstrate conceptual understanding through error analysis. Teachers receive guidance to set up a classroom store, and students use the store as a place to apply what they have learned about money to a real-world, ongoing application. In the Unit 5 Lesson 24 Quiz students encounter routine procedural problems, evaluate the veracity of numerous expressions to represent a situation, and, using the information from the procedural and conceptual tasks, determine if the goal will be reached.

Math in Action lessons occur at the end of most units. These lessons focus on application problems where students apply procedural fluency and conceptual understanding to solve problems in a non-routine, real-world context.

The instructional materials reviewed for Ready Grade 4 meet the expectations for identifying the Mathematical Practices (MPs) and using them to enrich the mathematics content within and throughout the grade.

The MPs for each lesson are identified in the CCSS Focus section as part of the Lesson Overview. SMP TIPs are found in the Teacher Resource Book throughout the lessons, and these tips highlight the integration of particular MPs within the lessons. The MPs are also identified for each lesson in the Table of Contents for the Teacher Resource Book on pages A4-A7.

Some examples of where the MPs are identified and used to enrich the mathematics content include:

• Unit 2 Lesson 9: MPs 1, 2, 4, 5, 6, and 7 are identified in the Lesson Overview. The SMP TIP in the lesson for MP2 states, “Writing multi-step equations to represent word problems requires students to reason abstractly and quantitatively. To successfully complete this problem, students need to see that 2 + 1 is more than just an addition fact to be computed. They must see 2 + 1 as the quantity of hours worked in one day that will then be multiplied by the number of days worked.”
• Unit 4 Lesson 14: MPs 1, 2, 4, 5, and 7 are identified in the Lesson Overview. The SMP TIP for MP4 states, “Some students may be tempted to use the model alone as justification for saying that Adriana ate more. Encourage them to use the model mathematically by reasoning about the number of parts and sizes of the parts. Discuss how the number of parts in each bar relates to the denominators and how the number of shaded parts relates to the numerators.” The SMP TIP for MP7 states, “Students must apply knowledge of equivalent fractions to solve this problem. Encourage them to look for and make use of structure as they search for a viable common denominator. Ask: Could you rewrite 2/100 as tenths? [No. You would have to divide 2 by 10.] How could you rewrite 8/10 as hundredths? [Multiply both the numerator and denominator by 10 to get 80/100.]” The SMP TIP in the lesson for MP5 states, “Help students use benchmark fractions strategically. When students discuss their comparison, guide them to consider what benchmark fraction will be most helpful in solving a given problem. For example, in problems 10-13, 1 is a useful benchmark because both fractions in the problem are near 1 on a number line.”
• Unit 5 Lesson 23: MPs 2, 5, 6, and 8 are identified in the Lesson Overview. The SMP TIP in the lesson for MP8 states, “Point out to the students that there is repeated reasoning involved when converting from a larger unit to a smaller unit. The number given in the larger unit will always be multiplied by the number of smaller units that make up one larger unit.”

The instructional materials reviewed for Ready Grade 4 meet the expectation for carefully attending to the full meaning of each practice standard. Overall, the materials attend to aspects of the mathematical practices (MPs) during different lessons throughout the grade, so when taken as a whole, the instructional materials attend to the full meaning of each MP.

Examples of where the instructional materials attend to each of the MPs include:

• MP1: In Unit 5 Lesson 26 students make sense of and persevere in solving problems while finding missing side lengths when the perimeter is given.
• MP2: In Unit 2 Lesson 5 students reason abstractly and quantitatively as they translate between words, symbols, and bar models that represent the same multiplicative comparison. In Unit 2 Lesson 10 students reason abstractly and quantitatively as they reason about the remainder and what it means.
• MP4: In Unit 3 Lesson 12 students solve problems that involve division of whole numbers. The students can model the division problems with equations, bar diagrams, or an area model, and the students can use the model they choose to revise their initial solution if there are errors or it doesn’t make sense.
• MP5: In Unit 5 Lesson 25 students have the opportunity to choose from different tools as they engage with problems involving length. The SMP TIP in the lesson for MP5 states, “Encourage students to use and/or draw visual models when confronted with various problems. A visual model can be a useful tool in deciding the necessary steps to finding a solution. Visual models often make the problem seem more ‘real’ and less abstract.”
• MP7: In the Unit 1 Math in Action students discuss where they see place value in their solution to a problem and how their understanding of place value helps them understand the solution. In Unit 4 Lesson 13 students use the structure of fractions to determine what happens when fractions are multiplied or divided.
• MP8: In Unit 6 Lesson 32 students use repeated reasoning to classify a rhombus. The SMP TIP in the lesson for MP8 states, “Students have had many opportunities to identify right, acute, and obtuse angles. Students should be able to correctly place a rhombus in the Venn diagram using the patterns they have seen with other quadrilaterals.”

The instructional materials reviewed for Ready Grade 4 meet the expectation for prompting students to construct viable arguments and analyze the evidence of others. Overall, the materials offer students multiple opportunities to construct viable arguments and/or analyze the arguments of others throughout the materials.

Examples where students are prompted to construct viable arguments and analyze the arguments of others include:

• Unit 1 Math in Action students construct an argument as to why their estimate is reasonable for the expected number of visitors to a blog post about video games.
• Unit 3 Lesson 12 Question 16 students choose the correct answer out of four for a word problem. Then students answer: “Awan chose D as the correct answer. How did he get the answer? How can you tell that Awan’s answer doesn’t make sense?”
• Unit 4 Lesson 14 Practice and Problem Solving Workbook students are asked, “Can two fractions with the same numerator and different denominators be equal? Explain using words and numbers.”

The instructional materials reviewed for Ready Grade 4 meet the expectation for assisting teachers to engage students in constructing viable arguments and analyzing the arguments of others concerning key grade level mathematics detailed in the content standards. The materials provide teachers with SMP TIPs to help facilitate students to construct arguments and/or analyze the arguments of others.

Examples where teachers are supported to help students construct viable arguments and analyze the arguments of others include:

• Unit 2 Math In Action has a note for teachers during Plan It and Solve It that states, “Put students in pairs to discuss solution ideas. Ask them to also discuss the Reflect questions about Mathematical Practices. Remind students that there are always different ways to answer these questions.”
• Unit 3 Math In Action SMP Tip states: “Encourage students to explain and justify their ideas and to ask each other questions about their suggestions. Prompt them to demonstrate how their ideas could lead toward a solution.”

The instructional materials reviewed for Ready Grade 4 meet the expectations for explicitly attending to the specialized language of mathematics. Overall, the materials for both students and teachers have multiple ways for students to engage with the vocabulary of Mathematics.

• The Student Practice and Problem Solving Book has notes at the bottom of the pages where mathematical vocabulary is defined.
• The Teacher Resource Book has Lesson Vocabulary for each lesson with mathematical terms and their definitions.
• Teachers are prompted in the Teacher Resource Book to have students use precise mathematical language. For example, Unit 4 Lesson 20 Mathematical Discourse 1 states, “Discuss the meaning of “4/10 of a dollar” [40 cents, or 4 dimes] and “50/100 of a dollar” [50 cents, or 5 dimes].”
• Each lesson has an “English Language Learners” section in the Teacher Resource Book that contains some ways to support vocabulary development for all students.
• Lessons contain language objectives. For example, Unit 2 Lesson 7 states, “Orally define and use in discussion the key mathematical terms factor, factor pair, multiple, composite number, and prime number.”

The instructional materials reviewed for Ready Grade 4 meet expectations for distinguishing between problems and exercises. Each problem or exercise has a purpose.

Students are learning new mathematics and solving problems in the beginning stages of each lesson in the Use What You Know, Find Out More, Reflect, Picture It, and Model It sections. At the conclusion of lesson instruction, students complete exercises in the Guided Practice and Independent Practice that engage them in exercises to practice skills and in problems to apply learning.

The instructional materials provide problems and exercises in both the Ready Instruction book and the Practice and Problem Solving Book. For example, in Unit 3 Lesson 12 Modeled and Guided Instruction students complete division problems using an area model and partial products methods that include making meaning of remainders. During Guided Practice students solve division exercises with remainders using area models and partial quotients. During Independent Practice students solve multiple choice problems that require them to demonstrate their use and understanding of division with and without remainders.

The instructional materials reviewed for Ready Grade 4 meet the expectations that the design of assignments is not haphazard and that the exercises are given in intentional sequences.

Problem sets and daily practice exercises relate to the mathematical concept developed in each lesson. The sequence of topics in each unit is intentionally planned to move from working with concrete and pictorial representations to more abstract work with numbers and computation. Each unit has a progressions chart showing what students have learned in previous grades connected to what they will learn in Grade 4 and how this will relate to what they will learn in future grades. Each lesson has a Learning Progression section in the lesson overview of the Teacher Resource Book which states what was learned in the previous grade, what students are learning in Grade 4 how it relates the current lesson, and what will happen in the next grades.

Concepts are explored and developed in daily lessons and reinforced through partner work and independent practice. Lessons are designed using a scaffolded approach. Students are guided by the teacher in the beginning of instruction, move toward work with partners or in small groups, and finally work independently. For example, in Unit 3 lessons are sequenced to build understanding of and fluency with multiplication and division with multi-digit whole numbers. Instruction begins in Lesson 11 with students multiplying one-digit and two-digit numbers by multiples of ten before multiplying two two-digit factors using area models, partial sums and the standard algorithm. In Lesson 12 students divide using the same area model representations and are asked to provide the related multiplication equations. Finally, students use the various strategies learned for multiplying and dividing in Unit 3 to complete the Math In Action lesson where they use and apply all operations with whole numbers as well as estimation.

The instructional materials reviewed for Ready Grade 4 meets expectations that there is a variety in what students are asked to produce.

Students are expected to respond and produce solutions in various ways. They are asked not only to produce answers but to provide evidence through drawings, representations, and written explanations. Students are often asked to analyze and defend the work of others. They must justify their conclusions with verbal statements and mathematical reasoning.

Lessons are designed with a consistent routine that includes whole group, partner, and independent work. The Picture It, Model It, Connect It, and Try It portions of each lesson require students to represent the problem in a drawing and make connections between the drawing and the equations. The Pair/Share portion of each lesson asks students to discuss their approaches to solving problems with another student, promoting students to justify their work and reason through the work of others. Question types vary and include multiple choice, true/false, draw a model, short answer, solve, explain, find the mistake, and multi-step performance tasks. Students are asked to produce various answers for the mathematical content that is the focus of each lesson. For example, in Lesson 25 students complete open-ended questions based on reading a short paragraph, use bar models, pictures, and number lines to solve problems, solve problems involving measurement conversions, and answer multiple choice questions.

The instructional materials reviewed for Ready Grade 4 meet expectations for providing manipulatives that are faithful representations of the mathematical objects they represent and when appropriate are connected to written methods.

In the Hands-On Activities found within each lesson students use a variety of manipulatives including number cubes, unit cubes, fact triangles, hundreds charts, base-ten blocks, place value charts, number cards, clocks, stopwatches, volume containers, pattern blocks, and square tiles. Students are frequently asked to look at a manipulative model and create a math equation from the representation. For example, in Lesson 20 students add fractions of tenths and hundredths by looking at pictures of base-ten blocks shaded to represent the fractions.

Throughout the materials, various manipulatives are introduced and used in lessons. Their use is appropriate for the mathematics content represented. For example, in Lesson 17 students use fraction circles to model addition of fractions in the Hands on Activity. Students discuss and make sense of the models, connecting them to the written expression the teacher is instructed to write on the board.

The instructional materials reviewed for Ready Grade 4 meet expectations that materials support teachers in planning and providing effective learning experiences by providing quality questions to help guide students' mathematical development. Support is provided in the following ways:

• Step by Step in each lesson organizes content into chunks for student learning and includes guiding questions, key points, and teacher prompts. For example, in Lesson 15 students explore fractions on a number line. During Guided Instruction teachers are prompted to ask: “Can you think of another way to show finding a difference on a number line?” Teachers are told, “Students may mention adding up to subtract.”
• The Mathematical Discourse section in each lesson includes questions to engage students and advance their mathematical understanding. For example, Lesson 11 Mathematical Discourse asks: “If you have a multiplication problem such as 100 x 12, will it change your answer if you write it as 12 x 100?” Teachers receive information on why the answers are the same and how this is an example of the commutative property. “Students may understand the concept, but may not know the name. It states that regardless of the order in which you multiply two numbers, the product is always the same.”

The instructional materials reviewed for Ready Grade 4 meet expectations that they contain a teacher's edition with ample and useful annotations and suggestions on how to present the content in the student edition and in the ancillary materials. Where applicable, materials include teacher guidance for the use of embedded technology to support and enhance student learning.

• Interactive Tutorials are referenced as part of Day 1 instruction for most lessons and provide interactive video clips for delivery of student mathematical learning.
• i-Ready Door 24 Plus is a free iPad app for fact fluency practice but is not explicitly included in the Teacher Resource Book for instruction.

i-Ready (available for additional purchase and used by most Ready users) is an Online Diagnostic and Instruction component.

The instructional materials reviewed for Ready Grade 4 meet expectations for containing a teacher’s edition in print and online that contains full, adult-level explanations and examples of the more advanced mathematics concepts in the lessons so that teachers can improve their knowledge of the subject, as necessary.

In each lesson, information is provided for the teacher to understand and make connections between the mathematical content and practices, errors or misconceptions that may arise, and the rationale behind specific lesson parts.

• In Unit 4 Lesson 22 the SMP TIP for MP8 states, “Students make use of regularity in repeated reasoning by applying the same processes that they developed in earlier grades to compare whole numbers. Ask students why this process works for decimals but not for fractions. [Decimals use the principles and patterns of base ten place value, but fractions often have denominators that are not multiples of ten.]”
• In Unit 6 Lesson 33 the Learning Progression states, “In this lesson students build on their understanding to reason about lines of symmetry in two-dimensional figures. … In Grade 5 students will extend their understanding of geometric concepts when they solve mathematical problems using the coordinate plane.”

Throughout Ready Grade 4 there is guidance for teachers that identifies and connects the underlying mathematics of a lesson. These are written in adult language.

The instructional materials reviewed for Ready Grade 4 meet expectations for containing a print teacher’s edition (in print and in the on-line Teacher Toolbox) that explains the role of the specific grade-level mathematics in the context of the overall mathematics curriculum.

Each unit begins with a Lessons Progressions Chart. This chart begins by listing lessons that students are building upon. These lessons can come from previous grades and from Grade 4. For example, Unit 4 Lesson 15 builds upon Grade 3 Lessons 16 and 17 and Grade 4 Lesson 13. The chart also lists lessons that students are preparing for. For example, Unit 6 Lesson 32 is preparing students for Grade 5 Lessons 30 and 31.

Each Lesson Overview includes a Learning Progression section. This section begins with an explanation of how the lesson builds on prior knowledge from Grade 3. The Learning Progression explains the lesson's overall connection to Grade 4 and the mathematical content of the lesson. This section also explains connections to Grade 5 and, if appropriate, to other future grades.

The instructional materials reviewed for Ready Grade 4 meet expectations for providing strategies to help teachers sequence or scaffold lessons so that the content is accessible to all learners.

• Each lesson follows a gradual release model in which scaffolded support is withdrawn as students gain mastery. Each lesson consists of four components: Introduction, Modeled and Guided Instruction, Guided Practice, and Independent Practice.
• Lessons are sequenced to build from conceptual understanding, using concrete and pictorial representations to more abstract representations.
• The marginal notes in the Teacher Resource book often suggest ways to support students as a whole and subgroups of students who might need extra support. Notes include sections on vocabulary, concept extensions, visual models, hands-on activities, and real-world connections.
• Each lesson contains a Differentiated Instruction page which contains an Intervention Activity, On-Level Activity, and a Challenge Activity.
• Center Activity PDF’s can be found online in the Teacher Toolbox to help further differentiation.

The instruction materials reviewed for Ready Grade 4, meet expectations for providing teachers with strategies for meeting the needs of a range of learners.

The Teacher Resource Book contains the following support:

• Each lesson includes a section called Small Group Differentiation that consists of three subsections: Reteach, Teacher-led Activities, and Student-Led Activities. Specific lessons from earlier in the material, as well as the previous grade-level material in the series, are identified and can be used to review or fill in gaps in student knowledge. Student–led Math Center activities in three different levels are referenced for additional instruction, if needed.
• The marginal notes in the Teacher Resource Book suggest ways to support students as a whole and provide specific strategies for subgroups of students who might need extra support. This includes sections on vocabulary, concept extensions, visual models, hands-on activities, and challenge activities.
• The Math In Action section for each unit has a Differentiated Instruction page that includes an Intervention and a Challenge Activity.
• The student Practice and Problem Solving book includes three levels of problems (basic, medium, challenge) that include verbal, visual, and symbolic representations.

Grade 4 Ready instructional materials meet expectations for embedding tasks with multiple entry-points that can be solved using a variety of solution strategies or representations.

When solving problems, students often choose their own solution strategy and/or representation. The embedded tasks are presented using multiple representations (drawings, charts, graphs, numbers or words) and different solution strategies.

• In Unit 2 Lesson 6 students are guided through a multiplication word problem using a bar model and the context of the problem to build the equation.
• In Unit 4 Lesson 20 Hands-on Activity students use 10-inch squares of paper to mark intervals of 10 vertically to create and explore a model of tenths and then horizontally to explore hundredths. In Lesson 21 Visual Model the teacher uses a place value chart and guides students in finding parallels between tens and tenths, and hundreds and hundredths.
• Unit 3 Math in Action features open-ended problems with many entry points and more than one possible solution. For example, students are given data about worms (how much they eat in one day, cost of 1050 and 2950 worms, and how much food is available). Students then tell how many and what size package of worms can be purchased to use the amount of food available. Students are encouraged to solve the problem in different ways.

The instructional materials reviewed for Ready Grade 4 meet expectations for suggesting support, accommodations, and modifications for English Language Learners and other special populations that will support their regular and active participation in learning mathematics.

The Teacher Resource Book and online Teacher Toolbox contain the following support:

• ELL Support Tips are found in the margin notes of each lesson of the Teacher Resource Book. For example, Unit 2 Lesson 9: “Throughout this lesson you will need to provide extra support to give English Language Learners confidence to participate in class discussions. Give all students time to think through their response to a question. Wait at least 5 seconds, and up to 30 seconds, before calling on any student to answer. If a student’s comment is unclear try 're-voicing' the student’s comment.”
• Prerequisite lessons include specific ELL support as needed. For example, in Unit 4 Lesson 20 there is one prerequisite lesson. Prerequisite Lesson 14 (Grade 3) includes an English language Learners support that states: “Some students, especially ELL students, may need additional support with understanding and using the word unit. Connect the term to the base-ten blocks they use. Remind them the ones blocks are called 'unit' cubes.”
• A Differentiated Instruction page is included in some lessons of the Teacher Resource Book. For example, Unit 5 Lesson 28 Understand Angles includes an Intervention Activity, On-Level Activity, and a Challenge Activity.
• Math Center Activities are provided On Level, Below Level, and Above Level.

The instructional materials reviewed for Ready Grade 4 meet expectations for providing opportunities for advanced students to investigate mathematics content at greater depth.

Materials offer the following instructional support for advanced learners:

• Each lesson of the Teacher Resource Book provides a Challenge Activity that provides students who have mastered the concepts and skills of the lesson with a more sophisticated problem. For example, in Unit 3 Lesson 12 Challenge Activity students are solving two-step word problems involving division. Three problems with contexts that include remainders are given. For example, “Jeremy had a bag of 300 raisins. He kept 20 for himself. He wanted to evenly split the rest among 7 friends. How many raisins was Jeremy able to give each of his friends?”
• The Math In Action section for each unit of the Teacher Resource Book has a Differentiated Instruction page that includes a Challenge Activity. For example, Unit 4 Math in Action: Use Fractions and Decimals Challenge Activity Sports Picture Frame asks students if they can design a frame from five craft sticks without changing the instructions. If it cannot be done, students must explain how the instructions could be changed to complete the project.
• A Differentiated Instruction page that provides Challenge activities is included in some lessons of the Teacher Resource Book. For example, Unit 1 Lesson 1 Understand Place Value includes a Challenge Activity to find numbers around them and present the numbers using base-ten clues in two different ways. Students also write each number in standard form, word form, and expanded form.

The instructional materials reviewed for Ready Grade 4 meet the expectation for providing a balanced portrayal of various demographic and personal characteristics.

• The names and situations in the story problems represent a variety of cultural groups.
• Student edition pictures include students from a variety of cultures.
• The Let’s Talk About It section in each lesson includes four faces of various demographics and represents both genders.
• The application problems include real-world situations that are appropriate to a variety of cultural and gender groups.
