Evaluation for 5.2d
Materials contain embedded supports for teachers to guide students toward increasingly efficient approaches.
The materials contain embedded supports for educators to guide students toward increasingly efficient approaches in various lessons of unit 2 of the
Grade 6 Advanced Mathematics course. For example, each lesson Overview page features a section titled Overview of Process Standards that explains how the lesson incorporates certain process standards. In the unit 2, lesson 1 Overview page, this section states, “In this lesson, students will create and use representations to organize, record, and communicate mathematical ideas. Students can use and connect various representations in the following ways: Describe connections among the ways a ratio is represented with concrete models, fractions, and decimals. Describe connections among the ways a percent is represented with concrete models, fractions, and decimals. Use several representations to explain what a percent is and interpret that percent in the context of a problem.” Another section in each lesson, Prior Learning Supports, describes how the lesson extends from similar content in previous lessons and grade levels. The example from “unit 2, lesson 1 states, “Ratios and percents are topics that are new to 6th grade advanced math. However, students previously used visual models to represent fractions and decimals. 3.3A expects the student to represent fractions greater than zero and less than or equal to one with denominators of 2, 3, 4, 6, and 8 using concrete objects and pictorial models, including strip diagrams and number lines. 4.2F expects students to compare and order decimals to the hundredths using concrete and visual models. Students often represent fractions using strip diagrams and decimals using hundreds grids. Both models represent parts of a whole and show equivalence among fractions, decimals, and percents. Students may also use these models to compare part-to-part ratios within a whole.” A third section in each lesson Overview page, Teaching Hints, gives educators hints and information to assist students. In this lesson, the hints for the educator state, “Ratios and percents are new to 6th grade advanced math students. Anchor this content in students’ prior knowledge about equivalent fractions. Manipulatives such as proportionality rods (e.g., Cuisenaire® rods) can help students visualize ratios and how different quantities relate to one another. Visual models such as hundreds grids allow students to see the relationships between percents and decimals.”

For example, each lesson Overview page features a section titled Overview of Process Standards that explains how the lesson incorporates certain process standards. In the unit 2, lesson 3 Overview page, this section states, “In this lesson, students will communicate mathematical ideas, reasoning, and their implications using multiple representations. Students can communicate in the following ways: Use visual models to show how a fraction, decimal, and percent represent the same quantity. Describe, using words, how they know a fraction, decimal, and percent are equivalent.” Another section in each lesson, Prior Learning Supports, describes how the lesson extends from similar content in previous lessons and grade levels. The example from unit 2, lesson 3 states, “Percents are new to 6th grade advanced math. However, students previously used visual models to represent equivalent fractions (Grade 3 and Grade 4) and related decimals to fractions (Grade 4). Percents were introduced in
Grade 6 Advanced Mathematics, Unit 2 Lesson 1. 4.2G The student is expected to relate decimals to fractions that name tenths and hundredths. 4.3C The student is expected to determine if two given fractions are equivalent using a variety of methods. 4.3D The student is expected to compare two fractions with different numerators and different denominators and represent the comparison using the symbols >, =, or <. 3.3F The student is expected to represent equivalent fractions with denominators of 2, 3, 4, 6, and 8 using a variety of objects and pictorial models, including number lines. In 3rd grade, students used number lines and pictorial models to represent equivalent fractions with denominators of 2, 3, 4, 6, and 8.” A third section in each lesson Overview page, Teaching Hints, gives educators hints and information to assist students. In this lesson, the hints for the educator state, “Visual models are helpful for students to understand how a number between 0 and 1 can be represented in different ways. When making comparisons between models, remind students that parts can only be compared if the regions representing the whole have equal areas.”
