The instructional materials reviewed for EdGems Math Grade 6 meet expectations for assessing grade-level content.

Each unit includes Form A and Form B Assessments as well as Tiered Assessments Form AT and Form BT, all of which include selected response and constructed response sections. Performance Tasks are also included with each unit. In addition, Gem Challenges are online, standards-based items for use after a standard has been addressed and are located after certain lessons. 

Examples of grade-level assessments include: 

  • Lesson 2.5, Dividing Decimals, Online Gem Challenge 1, Problem 3: “Use the fact 9 x 324 = 2916.” “Find the exact product of 0.9 x 3.24.” (6.NS.3)
  • Unit 3, Percents, Form B, Part II, Problem 10: “Gonzalez bought a new duffle bag that had a price tag of $28.00. He bought it in California which has an 8% sales tax. How much did Gonzalez pay for the duffle bag, including sales tax?”(6.RP.3c)
  • Unit 5, Expressions, Form B, Part I, Problem 2: “Four friends went to dinner. The taxi ride to the restaurant cost $15. Each person ordered a hamburger for $6. Which of the following expressions would calculate the total cost of the outing? Circle all that apply. A. 4×6+15, B. 4(15+6), C. 15+6+6+6+6, D. 4+6+15, E. 4×6×15 ” (6.EE.3)
  • Unit 7, Rational Numbers & the Coordinate Plane, Performance Task, Errand Run, “Lucy ran errands on Saturday. She wanted to create a map on a coordinate plane to illustrate the path she followed. She started at her home which was located at (2, −7). First, she went to the library to return some books. The library was located exactly 6 units north of her home on the map. She then went to the store to buy some milk. The store was located at (−5, −1). Before returning home, she went to the gas station to fill up her tank. The gas station was 6 units south of the store. Then she returned home.” Question 1. “Create a map for Lucy showing the path she traveled.” (6.NS.8) Question 2. “What shape best describes the shape that was formed by her path? Explain your answer.” (6.G.3) Question 3. “If each unit on the grid represents 0.5 miles, how many miles did she travel in all? Use words and/or numbers to show how you determined your answer.” (6.NS.8)
  • Unit 6, One-Variable Equations, Form A, Part II, Problem 1: “Determine if the number given is the solution of the equation. y + 11 = 17; Is 6 the solution? Explain how you know.” (6.EE.5)

There are above grade-level assessment items that could be modified or omitted without impact on the underlying structure of the instructional materials. These items include:

  • Unit 8, Form A, Part I, Problem 6: “Which of the graphs below show the equation ???? = 2x + 3?” Students find an equation in the form of y = mx + b from a line on a coordinate grid. (8.F.1,3)
  • Unit 8, Form A, Part II, Problems 7 and 8: “Graph each equation. 7. y = 1 + 3x and 8. y = = 12 − 2x.” (8.F.1,3)
  • Unit 3, Form A, Part II, Problems 12: “A scooter was originally priced $300. It went on sale for 20% off. It was still not selling so it was discounted an additional 20% off the sale price. Jules bought the scooter. How much did Jules pay for the scooter?” (7.RP.3)
  • Unit 3, Tiered Assessment, Problem 10: “A purse costs $100. It went on sale for 40% off. Since it was still not selling, the store marked it down an additional 10% off the sale price. How much will the purse cost after the additional mark-down?” (7.RP.3)

Criterion 1.2: Coherence

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

The instructional materials reviewed for EdGems Math Grade 6 meet expectations that supporting work enhances focus and coherence simultaneously by engaging students in the major work of the grade. Supporting standards and clusters are connected to major standards and clusters of the grade, and lessons address supporting standards while maintaining focus on the major work of the grade. Examples of supporting work being used to support the focus and coherence of the major work of the grade include:

  • Lesson 1.4 connects 6.NS.3 with 6.RP.3 as students divide decimals to compare unit rates. For example, “The Rodriguez family filled their car with gas while on vacation. They spent $45.60 and put 16 gallons in their car on Monday. On Friday, they spent $33.48 for 12 gallons of gas. On which day did they spend more per gallon? How much more?”
  • Lesson 5.6 connects 6.NS.4 with 6.EE.3 as students find and use the greatest common factor or least common multiple to factor expressions. For example, “Factor each expression using the greatest common factor. a. 48 + 60  b. 6x − 9.”
  • Lesson 9.1 connects 6.G.1 and 6.RP.3 as students find the area of rectangles and triangles and apply understanding of ratios to solve problems. For example, “Square A has side lengths of 8 inches. The ratio of Square A’s side lengths to Square B’s side lengths is 2:3. What is the area of Square B? Students must apply understanding of ratios to find the missing side length of Square B.”
  • Lesson 9.2 connects 6.EE.2c and 6.G.1 as students substitute a value for a variable in order to determine the dimensions to find the area of a triangle. For example, “The base of a triangle is represented by 2y + 6 and the height represented by 2y + 3. When the value of y is 10, what is the area of the triangle?”
Indicator 1D
01/02
The amount of content designated for one grade level is viable for one school year in order to foster coherence between grades.

The instructional materials for EdGems Math Grade 6 partially meet expectations that the amount of content designated for one grade level is viable for one year. 

As designed, the instructional materials can be completed in 121-160 days. If teachers followed the pacing guide, and used the minimal amount of days allocated, the materials would not be viable for a full school year. If teachers followed the pacing guide, and used the maximum amount of days allocated, the materials would be viable for a full school year. Considering the variability of instructional days, these materials partially meet expectations that the amount of content designated for one grade level is viable for one year.

The materials include ten units containing 49 lessons. Lessons range in length from one to four days. Each unit includes lessons, assessments, and targeted interventions.

  • The Pacing Guide designates four lessons as 1-2 days, 27 lessons as 2-3 days, one lesson as 3-4 days, one lesson as 2-4 days, 13 lessons as 2 days, and three lessons as 3 days leading to a total of 98 - 132 lesson days.
    • 4 lessons = 4 to 8 days.
    • 27 lessons = 54 to 81 days.
    • 1 lesson = 3 to 4 days.
    • 1 lesson = 2 to 4 days.
    • 13 lessons = 26 days.
    • 3 lessons = 9 days
  • Lesson length is 45-60 minutes.
  • The Pacing Guide designates 23-28 days for assessments and targeted review. Each unit has a range of lesson days and a total amount of days including assessments and targeted review. Assessments within each unit include: Exit Cards, Gem Challenges, Performance Tasks, Rich Tasks, Unit Assessments and Tiered Assessments.

Materials are consistent with the progressions in the Standards i. Materials develop according to the grade-by-grade progressions in the Standards. If there is content from prior or future grades, that content is clearly identified and related to grade-level work ii. Materials give all students extensive work with grade-level problems iii. Materials relate grade level concepts explicitly to prior knowledge from earlier grades.

The instructional materials for EdGems Math Grade 6 meet expectations for being consistent with the progressions in the Standards. In general, the instructional materials clearly identify content from prior and future grade-levels and use it to support the progressions of the grade-level standards. In addition, the instructional materials give all students extensive work with grade-level problems.

Each Unit Overview describes how the work of the unit is connected to previous grade level work, for example:

  • The introductory paragraph of the Unit 7 Overview, Rational Numbers and the Coordinate Plane, states, “In this unit, students will be introduced to the rational number system, which includes negative numbers. They will describe situations using positive and negative integers. They will find absolute values and compare rational numbers. Students will graph inequalities on a number line and write inequalities that model real world situations. Students will also be introduced to all four quadrants in the coordinate plane (as they have only graphed in the first quadrant previously). Vertices of quadrilaterals will be graphed on the coordinate plane. Students will use previous knowledge about different types of quadrilaterals to name figures on the coordinate plane and find the ordered pair for a missing vertex.”

Each Unit Overview includes Learning Progression, and each Learning Progression includes statements identifying what students have learned in earlier grades and what students will learn in future grades, for example:

Unit 1: Ratios and Rates, In earlier grades, students have…

  • Interpreted a fraction as a division problem (5.NF.3)
  • Multiplied fractions (5.NF.4-6)
  • Converted measurements (4.MD.1)

In future grades, students will…

  • Compute unit rates with ratios of fractions (7.RP.1)
  • Recognize and represent proportional relationships (7.RP.2/8.EE.5)

In some units, the Unit Overview references connections to current, grade-level work that was addressed in prior units. Examples include:

  • Unit 6, One-Variable Equations, the introductory paragraph includes, “Students will connect their understanding of percents from Unit 3 with the percent equation to find the whole when given the percent and a part.” 
  • Unit 8, Two-Variable Equations, the introductory paragraph includes, “Connections will be made to ratios from Unit 1 and graphing ordered pairs in Unit 7.”

The instructional materials present opportunities for students to engage with grade-level problems within each Student Lesson, Explore activity, Student Gem (online activities to provide practice with the content), Online Practice & Gem Challenge (only in some lessons), Exit Card, and Performance Task. There are also additional worksheets in each lesson for Proficient Practice, Tiered Practice, and Challenge Practice. For example:

  • In Lesson 7.5, students have multiple opportunities in the lesson to attend to each part of 6.NS.8. “Plot each set of points on a coordinate plane. Connect the points in the order given and connect the last point to the first point. Name the shape with all terms that apply (parallelogram, rectangle, rhombus, square and/or trapezoid). Exercise 6. (0, 4), (0, 0), (4, 0), and (4, 4).” Exercise 25. “Explain in words how to find the distance between (−4, 5) and (2, 5).”
  • In Lesson 5.2, students, “Find the value of 7×(85)2+27 \times (8 - 5)^2 + 2.” During Tiered Practice, Problems 1 - 4, students “Number the operations in the order they should be performed:  _____ Grouping Symbols; _____ ; Addition & Subtraction _____; Multiplication & Division _____ Powers.” Proficient Practice, Problem 9, “Three friends go to the movies. Each ticket costs $7. They also buy popcorn for $6, candy for $4 and a drink for $2. The friends want to split the total cost evenly. Write a numerical expression to represent this situation and determine how much each friend owes.” Challenge Practice: “Insert the operations (×, ÷, +, -) in each box of the numerical expressions to make it equal to the stated amount.” Problem 8, “(10221)(34)=7(10^2 \Box 2 \Box 1) \Box (3 \Box 4) = 7.” (6.EE.1)

The materials include two examples of off grade-level content that are not identified:

  • In Lesson 3.4, Problem 20, students use proportional relationships to solve multistep ratio and percent problems (7.RP.3). “Elli wants a pair of jeans that were originally priced $44. They were marked down 25% and then an additional 10% of the sale price. How much do the jeans cost now?”
  • In Lesson 8.3, students graph two-variable equations that are above grade level. In Exercise 17, “Graph the equation y=2+x2y = 2 + x^2” (8.F.3), and in Exercise 19, “Write the linear equation of a line that goes through the points (2, 5) and (4, 13).” (8.F.4)

Each unit includes a Parent Guide with Connecting Math Concepts, which includes, “Past math topics your child has learned that will be activated in this unit and Future math this unit prepares your child for.” For example, in Unit 4, Fraction Operations, Parent Guide, “Past math topics your child has learned that will be activated in this unit include finding and interpreting quotients of whole numbers less than 100 and multiplying fractions by whole numbers and fractions by fractions.” “Future math this unit prepares your child for includes applying and extending previous understandings of multiplication and division of fractions to multiply and divide rational numbers and solving equations with rational coefficients.”

Each Lesson Guide includes Teaching Tips, which often include connections from prior or future grades, for example:

  • Lesson 1.2, Ratio Tables and Graphs, Teaching Tips section, “Students have graphed points in Grade 5 in the Common Core State Standards but they may need to review how to graph in the first Quadrant of the coordinate plane.” 
  • Lesson 3.2, Percents, Decimals, and Fractions, Teaching Tips section, “In Grade 4 of the Common Core State Standards, students worked with decimal fractions to help them see the connections between the decimal name and the fraction. Use this knowledge to help students see decimals as a ratio compared to a power of ten, with the goal of having the denominator equal 100.”
  • Lesson 7.4, The Coordinate Plane, connections to future grades are stated. “In Grade 6 Common Core State Standards, students are asked to find distances between points that have the same x-coordinate or the same y-coordinate. In Grade 8 standards, students find distances between points that do not fall on the same horizontal or vertical line using the Pythagorean Theorem.”

In each Lesson Guide, Warm Up includes problems noted with prior grade-level standards. For example:

  • Lesson 3.1, Introducing Percents, Concepts and Procedure (4.NF.1), Question 27, Skill: Simplify each fraction.
    • a. 25/100 
    • b. 60/100
    • c. 84/100
    • d. 28/100
    • e. 54/100
    • f. 76/100
  • Lesson 8.1, Input-Output Tables, Concepts and Procedure (3.OA.9), Question 26, Skill: Describe the operation used to calculate the next term in each list of numbers. Give the next two numbers in the list.
    • a. 1, 4, 7, 10, _____, _____ 
    • b. 40, 35, 30, 25, _____, _____
    • c. 4-2/5 , 4, 3-3/5 , 3-1/5, ______, _____
    • d. 2.4, 4, 5.6, 7.2, _____, _____

  • Lesson 2.4, Gem Challenge 1, students find the exact quotient for several problems (6.NS.2). For example, Question 1, “Divide 19,008 ÷ 32. Find the exact quotient.” Online Practice, Question 4 states, “What is the remainder on the quotient of 1,743 divided by 11?”
  • In Lesson 2.4, Dividing by Multi-Digit Numbers, students develop the procedural skill of dividing multi-digit numbers with multiple problems. For example, Proficient Practice, Problem 12, “Charlie had 150 feet of wire. If he cut the wire into 12 equal pieces, how long was each piece of wire?” (6.NS.2)
  • In Lesson 5.3, Variables and Expressions, Student Gems link to Khan Academy Quiz: "Write an expression to represent: The sum of ten and the quotient of a number x and 6”. Students are provided multiple practice problems to develop procedural skills. (6.EE.2a)
  • Lesson 5.1, Teacher Gems, the activity, “Matho” includes nine numerical expressions that include exponents. The students evaluate the expressions to determine if their expressions match the numbers called in a bingo-like activity. (6.EE.1)
Indicator 2C
02/02
Attention to Applications: Materials are 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

The instructional materials for EdGems Math Grade 6 meet expectations for being designed so that teachers and students spend sufficient time working with engaging applications of the grade-level mathematics. Engaging applications include single and multi-step problems, routine and non-routine, presented in a context in which the mathematics is applied. 

The instructional materials include multiple opportunities for students to engage in routine and non-routine application of mathematical skills and knowledge of the grade level. Students engage with materials that support non-routine and routine applications of mathematics in the Explore! activities, Teacher Gems, Performance Tasks, and Rich Tasks. Some of the Student Pages and Proficient, Tiered, and Challenge Practice allow students to engage with problems including real-world contexts and present multiple opportunities for students to independently demonstrate application of grade-level mathematics. Examples include:

  • Lesson 1.4, Comparing Rates, the Explore! Activity, students apply ratio and rate reasoning in real-world problems. (6.RP.3) “Kimiko has two summer job options. She has a daily babysitting job she could do where she gets paid the same hourly rate for each hour she babysits. For a 3 hour babysitting job, she earns $21. She also has the option of helping in her mother’s laundromat. Her mom pays her $64 for every 8 hours she works.” Students complete ratio tables for each job and solve problems about the situation.
  • Lesson 4.3, Dividing Fractions, Student Lesson, students apply dividing fractions in real-world examples (6.NS.1). “Shiloh drives 3/4 mile to school each day. There is a stop sign every 3/8 mile. How many stop signs will she pass on her way to school?” 
  • Lesson 9.3, Area of Composite Figures, Explore! activity, students apply finding area of special polygons in real-world situations. (6.G.1) “Kienan worked for a landscaping company. He was assigned to determine how much bark was needed to put in the kids’ play area at a new park. He was given the blueprint of the polygonal play area. Some dimensions were given on the drawing and others were not. Step 1: Determine the area of the entire play area. Show your method for calculating the area and show all needed dimensions, if not given.” 
  • In Lesson 6.2, Solving Addition and Subtraction Equations, Proficient Practice, students independently apply solving equations with rational numbers in a real-world example, “At the market, Sydni puts a few pears in a bag then weighs the bag on a produce scale. The bag of pears weighs 4.75 pounds. She adds more pears to the bag. The new weight of the bag is 5.6 pounds. Write and solve an addition equation to find the weight of the pears added to the bag.” (6.EE.7)

Balance: The three aspects of rigor are not always treated together and are not always treated separately. There is a balance of the 3 aspects of rigor within the grade.

The instructional materials for EdGems Math Grade 6 meet expectations that the three aspects of rigor are not always treated together and are not always treated separately.

All three aspects of rigor are present independently throughout the program materials. Examples include:

  • In Lesson 5.1, Powers & Exponents, students build fluency in writing exponents. For example, Student Lesson, “Write the numerical expression as a power. 3 × 3 × 3 × 3 × 3", students practice this skill with multiple problems including decimal numbers and fractions. (6.EE.1)
  • In Lesson 5.5, Equivalent Expressions, Example 1, students demonstrate conceptual understanding by using a visual representation of a table to compare and test expressions to determine if they are equivalent. Students are instructed to, “Show that 2x + 5 and x + 3 + x + 2 are equivalent expressions. Create a table of values to test different input values.” (6.EE.4) 
  • In Lesson 7.3, Inequalities, Teacher Gems Station activity, students write inequalities to represent real-world situations and work with non-routine problems (6.EE.8). The Stations activity includes tasks that students engage with as they move from station to station. One example included is Station 1: “Write an inequality for the statement: The amount of money Jacob has in his bank account, m, is more than $300.” Station 3: “Write an inequality for the statement: The amount of time Ronnie practices guitar, g, is less than 15 hours a week.” Station A: “Describe a situation modeled by the inequality: x < 15.”

Multiple aspects of rigor are engaged simultaneously to develop students’ mathematical understanding of a single topic/unit of study throughout the materials. Examples include:

  • In Lesson 1.2, Ratio Tables and Graphs, students develop conceptual understanding within an application problem. In Question 7, students explain how to use a ratio table to find a specific value (6.RP.3a). An example included is “Kyle sells sandwiches at the deli. He sells five turkey sandwiches for every two ham sandwiches. a. Create a ratio table showing the number of turkey sandwiches sold compared to ham sandwiches sold. Include four equivalent ratios. b. Explain how you could use a ratio table to find how many ham sandwiches were sold if 45 turkey sandwiches were sold. Include the number of ham sandwiches sold in your explanation.”
  • In Lesson 1.3, Rates and Unit Rates, Proficient Practice, students develop fluency in finding unit rates as they calculate unit rates in multiple situations. (6.RP.3) Examples included are Problem 13, “Keisha drove 100 miles in 2 hours. At this rate, how far will she drive in 6 hours?” Problem 14, “Jimmy paid $75 for 3 people to attend a play downtown. If it costs the same per ticket, how much will Alan pay for 10 people to attend the play next week?”
  • Lesson 4.4, Multiplying and Dividing Mixed Numbers, Student Gems link to Dan Meyer 3-Act Math tasks, students develop conceptual understanding of multiplying and dividing mixed numbers within an application (6.NS.1). An example is Nana’s Lemonade where students watch a 3 part video, make predictions about the ratio of water to lemon juice, pose questions, answer questions, and compare their thinking with their peers.
  • In Lesson 3.3, Percents of a Number, students develop conceptual understanding simultaneously with procedural skill to find a percent of a quantity (6.RP.3c). The Explore! activity in this lesson provides students with a diagram of a grid representing a room with pieces of furniture and guides students through the process of finding the percent of the room taken up by each object. The directions state: “Kieran used a piece of 4 by 5 grid paper to sketch the floor plan of his room. He colored the location of his bed, dresser and desk.”
    • Step 1: Write the ratio of the parts shaded for each object to the total space as a fraction.
    • Step 2: Convert each fraction in Step 1 to a decimal fraction with a denominator of 100.
    • Step 3: What percentage of the room is taken up by each object?

The Standards for Mathematical Practice are identified and used to enrich mathematics content within and throughout each applicable grade.

The instructional materials reviewed for EdGems Math Grade 6 meet expectations for identifying the Standards for Mathematical Practice and using them to enrich mathematics content within and throughout the grade level.

All 8 MPs are identified throughout the materials. Each lesson includes a Lesson Guide with a section titled, Mathematical Practices - A Closer Look that explains a few of the MPs that will be used within that lesson. The MP is identified and an explanation of how to address the MP within the lesson is provided. At times, the identification is targeted, and gives a specific problem where the MP is included, but often it is broad and provides a general statement of how to include the MP within the lesson.

Examples of MPs that are identified and enrich the mathematical content include:

  • Lesson 1.2, Ratio Tables and Graphs, “MP1: Students are given the opportunity to make sense of a situation using Exercises 10 through 14. The amount of perseverance needed from students increases throughout this set. Students should ask themselves, “Does my answer make sense?” after reaching an answer for #14.”
  • In Lesson 5.4, Evaluating Expressions, “MP2: Have students substitute a variety of values into an expression representing a real-world scenario (like the taxi in Example 3). Have them discuss what the resulting value represents in terms of the situation.”
  • In Lesson 3.2, Percents, Decimals and Fractions, “MP5: In Example 3, a ratio table is used as a tool to convert a ratio to a percent. Students have many tools they have learned in previous years that they may choose to connect to new content to help it make sense to them. This should be encouraged.”
  • Lesson 7.3, Inequalities, “MP6: When students graph inequalities on a number line, they must pay attention to the inequality sign to determine whether or not the end point is filled in. They must also determine if the arrow should point to numbers greater than or less than the given number. Remind students that each aspect of the graph must be precise to represent the inequality correctly.”

Materials carefully attend to the full meaning of each practice standard

The instructional materials reviewed for EdGems Math Grade 6 partially meet expectations for carefully attending to the full meaning of each practice standard. 

The materials do not attend to the full meaning of MP4 and MP5. Throughout the materials MP4 is identified, however, most of the examples given for modeling use drawings and tools to solve rather than connect the content to real-world scenarios, thus not attending fully to the practice. Within the materials, students use tools, however, specific tools are given for the students to use without an opportunity to choose appropriate tools strategically. In addition, there are multiple places throughout the materials where MP2 is labeled, however, the description does not always fully attend to the practice, frequently focusing on finding key words in word problems instead of making sense of quantities and their relationships. Examples include:

  • MP2: In Lesson 2.1, Adding and Subtracting Decimals, Lesson Guide, students do not make sense of quantities and relationships as they look for keywords to solve word problems. “Students will need to choose the correct operation for each word problem. Brainstorm keywords they might see that will give clues about whether they should add or subtract when doing the exercises.”
  • MP2: In Lesson 3.3, Percents of a Number, Lesson Guide, “This lesson gives students the skills they will need to solve later word problems as they write equations involving percents and solve them. As such, work with students to understand the words “of ” as multiplying and “is” as equals so they can compute using percents in a decontextualized manner before having the context introduced.” Students look for keywords instead of making sense of quantities and relationships within the problem.
  • MP4: In Lesson 6.3, Solving Multiplication and Division Equations, “Algebra tiles can be used to show the process of solving multiplication equations by grouping. Students need to have a conceptual understanding of multiplication prior to successfully solving equations using this model.” This is a strategy for solving and does not attend to MP4 as students do not work with real-world situations.
  • MP4: In Lesson 1.2, Ratio Tables and Graphs, students visually represent the problem but are not modeling a real-world context. “...students use tape diagrams to model ratio relationships. In this lesson, students are given the opportunity to model ratios using tables and graphs. You may want to have students discuss the strengths and weaknesses of each model.” 
  • MP5: In Lesson 4.1, Multiplying Fractions, Lesson Guide: “Grid paper is an appropriate tool to use to show how to multiply two fractions. Have students create a rectangle with side lengths that correspond to each of the denominators of their fractions and then follow the process shown in the Explore! and Example 1.” Students are instructed on which tool to use.
  • MP5: In Lesson 2.3, Dividing by 1-Digit Numbers, Lesson Guide: “The Explore! has students using base-ten blocks to show division. Students will be trading in tens sticks for ones cubes in order to put a larger number into smaller equal-sized groups.” Students are instructed on which tool to use. 

Examples of the instructional materials attending to the full meaning of the MPs include:

  • MP1: In Lesson 3.4, Percents Application, “Students determine their solution strategy as well as identify whether their answer should be greater than (i.e., tax) or less than (i.e., discount) the original value (if they are not only computing the tax, tip or discount).” Students make sense of given values and use estimation strategies to solve multi-step problems in a real-world situation.
  • MP2: In Lesson 5.1, Powers and Exponents, “Encourage students to reason quantitatively regarding the possible size of powers. If they are raising a fraction less than one to a given exponent, will that make the solution smaller or larger? How about a number greater than one?” This example allows students to reason quantitatively about exponents.
  • MP7: In Lesson 5.2, Order of Operations, “Students make use of structure in this lesson as they put together all the components of the order of operations. Have students verbally share the order of operations structure with another student prior to working independently.” This allows students to engage and use the structure of the order of operations in various problems.
  • MP8: In Lesson 4.3, Dividing Fractions, “Use the Explore! to allow students to use repeated reasoning to discover that dividing by a fraction is the same as multiplying by the reciprocal.” This fits with the practice in that students are repeating a process to understand the concept.

Materials prompt students to construct viable arguments and analyze the arguments of others concerning key grade-level mathematics detailed in the content standards.

The instructional materials reviewed for EdGems Math Grade 6 meet expectations for prompting students to construct viable arguments and analyze the arguments of others concerning key grade-level mathematics. 

Examples of the student materials prompting students to construct viable arguments and/or analyze the arguments of others include:

  • In Lesson 1.4, Comparing Rates, students construct an argument to explain their work. Exercise 16: “Kent and Aleesha each live 5 miles from school and ride their bikes there every day. They left school at the same time on Thursday. After 5 minutes, Aleesha texted Kent that she had traveled 1 mile. After 15 minutes, Kent texted Aleesha saying he was halfway home. If they each traveled at a constant rate, who got home first? Explain how you know.”
  • One of the Teacher Gems activities is called “Always, Sometimes, Never.” The instructions for this type of activity state, “Always, Sometimes, Never is best used with concepts that allow for situations that create exceptions to the “rule” or require students to understand subcategories to fully understand the standard. Students are given the opportunity to create evidence to support whether a statement is always true, sometimes true, or never true.” For example, in Lesson 4.4 Multiplying and Dividing Mixed Numbers, the student directions for the Always, Sometimes, Never Activity state, “Decide if the statement in the box below is always true, sometimes true, or never true. Use the remainder of the page to provide mathematical evidence that supports your decision. Statement #1: The quotient of two fractions is the reciprocal of the product of those two fractions.”
  • In Lesson 9.2, Area and Perimeter with Decimals, Exercise 22, Students construct an argument to explain their work. “Two rectangles both have perimeters of 20 cm but have different areas. One of the rectangles has dimensions that are not whole numbers. The other rectangle has a length that is 6 cm longer than its width. Draw a set of two possible rectangles that fit these criteria. Show how your set of rectangles meet each of the criteria.”
  • In Lesson 1.1, Ratios, Problem 26, students analyze someone’s mathematical reasoning. “Dalexis says, “If you multiply a 2-digit number and a 1-digit number, you get a 3-digit number.” Is her statement always true, sometimes true or never true? Support your answer with your reasoning.”
  • In Lesson 2.4, Dividing by Multi-Digit Numbers, Exercise 13, students critique the reasoning of others and justify their thinking. “Vivaan said the answer to #10 above [5240 ÷ 160] should be the same as the answer to 524 ÷ 16. Is he correct? If so, explain why.”
  • Unit 3, Percents Performance Task, “Mack wants to sell his used car. He spends the first month trying to sell it for $5,000, but is unsuccessful. The second month he decides to sell the car at 50% off the original selling price. The car does not sell. The third month he discounts the car by an additional 50%. Now, his friend Jasper says he will buy the car because it is free. Jasper’s thinking is below: 50% + 50% = 100% discount = FREE! 1. Explain what is wrong with Jasper’s thinking. Include the percent of Mack’s original selling price Jasper would pay for the car if he buys it. Use words and/or numbers to show how you determined your answer.” Students critique the reasoning of others and justify their reasoning. 
  • Lesson 3.4, Percent Applications, students analyze a student’s work and provide mathematical reasoning to correct the strategy in Problem 14 of the student lesson, “Mikayla took her friends to lunch. The bill came to $32. She wanted to leave a 15% tip and needed to determine the total cost of the lunch, including the tip. Her work is below. Unfortunately, Mikayla made a mistake. Explain the mistake Mikayla made and then find the correct total for the bill.”

Materials assist teachers in engaging students in constructing viable arguments and analyzing the arguments of others concerning key grade-level mathematics detailed in the content standards.

The instructional materials reviewed for EdGems Math Grade 6 meet expectations for assisting teachers in engaging students to construct viable arguments and analyze the arguments of others concerning key grade-level mathematics. The Teacher/Lesson Guide and Teacher Gems within most lessons support teachers to engage students in constructing viable arguments and analyzing the reasoning of others. Examples include:

  • Lesson 1.1, Ratios, Teacher/Lesson Guide, Exercise 19b, supports teachers in engaging students in constructing viable arguments. “Exercise 19b could be used as an opener to the lesson as it builds upon previous knowledge. Groups can discuss if the situation is possible and create arguments for or against to share with classmates.” 
  • In Lesson 3.2, Percents, Decimals and Fractions, Teacher/Lesson Guide, Explore!, teachers engage students to construct an argument and justify their thinking. “In Step 5 of the Explore!, students will create differently shaded grids. Have them share their work with one another or as a class using a document reader and discuss whether or not the shaded grids accurately reflect the furniture in Tamika’s room. Have students emphasize their work in Step 4 as justification for their grids.”
  • Lesson 5.1, Powers and Exponents, Teacher/Lesson Guide, supports teachers to help students construct viable arguments. “Show one correct and one incorrect statement (e.g., 3⁴ = 81 and 3⁴ = 12). Ask students to find the correct statement and construct a viable argument as to why it is correct.”
  • Lesson 5.4, Evaluating Expressions, Teacher/Lesson Guide, supports teachers to help students critique the reasoning of others. Teachers are informed of a misconception: “It is very common for students to insert values into expressions using multiplication and lose the operation (i.e., 5y when y = 2 becomes 52).” Teachers are instructed to, “Show this common error on the board and see if anyone can figure out what you did wrong.”
  • In Lesson 6.1, Equations and Solutions, Teachers Gems, Partner, teachers assist students in constructing viable arguments and critiquing the reasoning of others. “After a rotation, if there is a lot of discrepancy in student answers as they compare with their new partner, the teacher can call a FREEZE. With a FREEZE, all students should put their writing utensils down then ask for a partner set where they got different answers on a specific task. These students hand over their templates for the class to examine (under a document camera) and provide feedback on. Having classroom sentence starters for the FREEZE component can be helpful in guiding the conversation such as “I like… I wonder… Your next step could be…”

Materials explicitly attend to the specialized language of mathematics.

The instructional materials reviewed for EdGems Math Grade 6 meet expectations for explicitly attending to the specialized language of mathematics. The materials provide explicit instruction in how to communicate mathematical thinking using words, diagrams, and symbols. Throughout the materials, precise terminology is used to describe mathematical concepts, and each lesson includes a visual lesson presentation. In most of the lesson presentations, there is at least one slide dedicated to explicit teaching of vocabulary. The Teacher/Lesson Guide, Student Lesson, and Parent Guide all contain information about mathematical language. Examples include:

  • In the Student Lessons, the font for vocabulary words is red and a definition is included.
  • Each unit includes a Parent Guide which contains “Important Vocabulary” related to the unit.
  • In Lesson 1.2, Ratio Tables and Graphs, the Lesson Presentation includes a slide dedicated to introducing vocabulary from the lesson and provides mathematical definitions. “Equivalent Ratios - A comparison of two quantities with the same value. Ratio Table - A model that shows multiple equivalent ratios."
  • In Lesson 6.1, Equations and Solutions, the Lesson Presentation includes a slide that provides the definitions and terms important to the lesson. “Equation - A mathematical sentence that contains an equals sign (=) between two equivalent expressions. Solution - Any value or values that makes an equation true.”
  • Lesson 5.1, Powers and Exponents, Teacher/Lesson Guide, Teaching Tips includes information about mathematical language, “People often use the word “squared” for power of 2 and “cubed” for power of 3. For example, students should understand that four squared means four to the power of 2, or 4².”
  • Lesson 7.1, Understanding Integers, Teacher/Lesson Guide, Teaching Tips includes information about mathematical language. “Addition and subtraction are inverse operations that “undo” one another. Positive and negative integers are opposites of one another. Be careful not to say addition and subtraction are opposites as this may confuse students.”
  • In Lesson 2.3, Dividing by 1-Digit Numbers, Online Practice, students identify a number based on accurate terminology. “In each expression determine if 4 is the ‘dividend’ or the ‘divisor’.”

Examples of not attending to the specialized language of mathematics include:

  • In Lesson 6.3, Solving Multiplication and Division Equations, Teacher/Lesson Guide, “MP6: In a division equation, students may struggle with seeing how multiplying both sides by the number in the denominator cancels out the value in the denominator. Show students the importance of writing the value they are multiplying by in the numerator, not in the denominator.” “Cancels out the value in the denominator” is not precise mathematical terminology.
  • In Lesson 2.1, Adding and Subtracting Decimals, Teacher/Lesson Guide, Teaching Tips, “Remind students, when adding or subtracting decimals, that once the problem is lined up properly the decimal points are ignored until the end when it is brought straight down and placed in the answer.” This teaching tip is not mathematically sound. Students should be conceptually aware of why a process is occuring versus simply stating a procedure. 
  • In Lesson 5.5, Equivalent Expressions, Teacher/Lesson Guide, “MP6: When combining like terms, help students attend to precision by understanding that the operation preceding each term ‘belongs’ to that term. When a term is being subtracted from a previous term, the subtraction sign should move with that term as a negative sign.” Student Lesson: “In order to simplify an algebraic expression you must combine all like terms. When combining like terms you must remember that the operation in front of the term (addition or subtraction) must stay with the term. Rewrite the expression by grouping like terms together before adding or subtracting the coefficients to simplify.” In both the Lesson Guide and Student Lesson, the explanation for combining like terms and the idea that the operation “belongs” to the term is not mathematically sound. Students should be conceptually aware of why a process is occurring versus simply stating a procedure.

Criterion 3.1: Use & Design

The underlying design of the materials distinguishes between problems and exercises. In essence, the difference is that in solving problems, students learn new mathematics, whereas in working exercises, students apply what they have already learned to build mastery. Each problem or exercise has a purpose.

The instructional materials for EdGems Math Grade 6 meet the expectations for distinguishing between problems and exercises. Each Unit presents lessons with a consistent structure. The instructional sections, which vary by day, include: Warm-Up, Introduction to lesson using Lesson Presentation, Explore! Activity, and Focused Assignment or Online Practice. 

Within the Teacher/Lesson Guide, the student work is referred to as exercises, activities, and independent student practice. For example:

  • In Lesson 2.1, Adding and Subtracting Decimals, Teacher/Lesson Guide, the lesson planning suggestion states, “This lesson may take 2 class periods (45-60 minutes per period). A suggested order for covering the content in this lesson in two days is below. Additional time may be given to use Tic-Tac-Toe activities or independent student practice. Day 1: Warm-up of choice from above, Lesson Presentation, Teacher Gem Activity (6.NS.3 Relay), Focused Assignment or Online Practice.”

Within the Student Lessons throughout the materials, multiple examples are provided to show the steps to take when working with the content. The students then practice the content out of context before working with the content in story problems within context. For example:

  • In Lesson 4.3, Dividing Fractions, Student Lesson, students learn the content by solving problems without context and apply the content in real-world contexts. “Find each quotient. Write your answer in simplest form. 5. 2/3 ÷ 1/3.” Near the conclusion of the problems, students evaluate the reasoning of others. “Two students solved division expressions. In Exercises 30 and 31, determine if the work shown by each student is correct and solve correctly if an error was made. Explain your reasoning.”

The instructional materials for EdGems Math Grade 6 meet the expectations for having a variety in what students are asked to produce. In the practice pages, students develop concepts and skills by answering multiple questions on the content. For example:

  • In Lesson 1.3, Rates and Unit Rates, Exercises, students find unit rates through multiple examples, “Find each unit rate. 1. 60 miles/2 hours”

Students connect content to real-world situations and gain extra practice through the Student Gems, linked resources from Open Educational online sites. For example:

  • In Lesson 5.2, Order of Operations, Student Gems from Desmos, students complete extra practice on the order of operations. Summary from the Desmos website, “In this activity, students use sketch to solve "twin puzzles" as a way to practice their order of operations skills. Teachers can use the overlay feature in the teacher dashboard to assess the class at a glance and to facilitate class-wide error analysis discussions, or the response view to identify individual students who need additional support.”

With the Teacher Gems, students create arguments and justify their answers. For example:

  • In Lesson 9.5, Volume of Rectangular Prisms, Teacher Gem: Partner Math, students solve problems involving the volume of rectangular prisms, they justify their answers to others to compare work, “4. Once the students have a new partner, they need to compare answers from the previous two tasks. If they agree, they sign their initials in the circle connecting the two task boxes. If students disagree, they work to determine who is correct prior to signing. Once students compare, the teacher should have posted what the next two tasks are and they work with this partner to complete the next two tasks.”

Students use the tiles to model multiplication equations and then balance their mats. The Explore! activity ends with students summarizing how to use the mats and tiles to model and solve multiplication equations. You may choose to discuss with students what it might look like to solve a division equation on a mat and what the model’s limitations are for this operation.”
  • Mathematical Practices - A Closer Look, contains information related to each Mathematical Practice contained in the lesson and suggestions for teachers. For example, in Lesson 1.5, Measurement Conversions, “MP6: Physically show students objects that represent different measurements so they understand better how one relates to another. Focus on the meaning of the prefixes used with metric measurements in the table at the beginning of the lesson. Encourage students to think of other words with these prefixes (e.g., decade for deca-).”
  • There are Extra Examples found in each of the lessons for teachers to present if needed.
  • Teaching Tips provide teachers with suggestions for teaching the content within the lesson. For example, in Lesson 9.4, Nets and Surface Area, Teaching Tip, “Encourage and point out different nets for the same solid.
