Chapter ResourcesGraphic Organizer (page 2) This master is a tool designed to assist students with comprehension of grade-level concepts. You can use this graphic organizer in coordination with the appropriate lesson. While the content and layout of these tools vary, their goal is to assist students by providing a visual representation from which they can learn new concepts.

Student Glossary (page 3) This master is a study tool that presents the key vocabulary terms from the chapter. You may suggest that students highlight or star the terms they do not understand. Give this list to students before beginning Lesson 3-1. Remind them to add these pages to their mathematics study notebooks.

Anticipation Guide (page 4) This is a survey designed for use before beginning the chapter. You can use this survey to highlight what students may or may not know about the concepts in the chapter. If feasible, interview students in small groups, asking them the interview questions in the guide. There is space for recording how well students answer the questions before they complete the chapter. You may find it helpful to interview students a second time, after completing the chapter, to determine their progress.

Games (page 5) A game is provided to reinforce chapter concepts and may be used at appropriate times throughout the chapter.

Resources for LessonsReteach Each lesson has an associated Reteach worksheet. In general, the Reteach worksheet focuses on the same lesson content but uses a different approach, learning style, or modality than that used in the Student Edition. The Reteach worksheet closes with computational practice.

Skills Practice The Skills Practice worksheet for each lesson focuses on the computational aspect of the lesson. The Skills Practice worksheet may be helpful in providing additional practice of the skill taught in the lesson. It also contains word problems that cover the skill. Spaces for students’ answers are provided on the worksheet.

Homework Practice The Homework Practice worksheet provides an opportunity for additional computational practice. The Homework Practice worksheet includes word problems that address the skill taught in the lesson. Spaces for students’ answers are provided on the worksheet.

Problem-Solving Practice The Problem-Solving Practice worksheet presents additional reinforcement in solving word problems that applies both the concepts of the lesson and some review.

Enrich The Enrich worksheet presents activities that extend the concepts of the lesson or offer a historical or multicultural look at the lesson’s concepts. Some enrich materials are designed to widen students’ perspectives on the mathematics they are learning.

Resources for Problem-Solving In recognition of the importance of problem-solving strategies, worksheets for problem-solving lessons follow a slightly different format. For problem-solving lessons, a two-page Reteach worksheet offers a complete model for choosing a strategy. For each Problem-Solving Strategy lesson, Reteach and Skills Practice worksheets offer reinforcement of the strategy taught in the lesson. In contrast, the Problem-Solving Investigation worksheets include a model strategy on the Reteach worksheets and provide problems requiring several alternate strategies on the practice worksheets.

Teacher’s Guide to Using the Chapter 3 Resource Masters

The Chapter 3 Resource Masters includes the core materials needed for Chapter 3. These materials include worksheets, extensions, and assessment options. The answers for these pages appear at the back of this booklet.

All of the materials found in this booklet are included for viewing and printing on the TeacherWorks Plus™ CD-ROM.

Assessment OptionsThe assessment masters in the Chapter 3 Resource Masters offer a wide variety of assessment tools for monitoring progress as well as final assessment.

Individual Progress Checklist This checklist explains the chapter’s goals or objectives. Teachers can record whether a student’s mastery of each objective is beginning (B), developing (D), or mastered (M). The checklist includes space to record notes to parents as well as other pertinent observations.

Chapter Diagnostic Test This one-page test assesses students’ grasp of skills that are needed for success in the chapter.

Chapter Pretest This one-page quick check of the chapter’s concepts is useful for determining pacing. Performance on the pretest can help you determine which concepts can be covered quickly and which specific concepts may need additional time.

Mid-Chapter Test This one-page chapter test provides an option to assess the first half of the chapter. It includes both multiple-choice and free-response questions.

Vocabulary Test This one-page test focuses on chapter vocabulary. It is suitable for all students. It includes a list of vocabulary words and questions to assess students’ knowledge of the words.

Oral Assessment This two-page test consists of one page for teacher directions and questions and a second page for recording responses. Although this assessment is designed to be used with all students, the interview format focuses on assessing chapter content assimilated by ELL students. The variety of approaches includes solving problems using manipulatives as well as pencil and paper.

Listening Assessment This two-page assessment contains one page for teacher directions and one page for responses/recordings. This assessment, too, is suitable for all students but is designed primarily for use with students who may have difficulty reading test materials. The assessment directions progress in difficulty from

simple at the beginning of the year to more extensive at the end of the year.

Chapter Project Rubric This one-page rubric is designed for use in assessing the chapter project. You may want to distribute copies of the rubric when you assign the project and use the rubric to record each student’s chapter project score.

Foldables Rubric This one-page rubric is designed to assess the chapter Foldable. It is written to the students, telling them what you will be looking for as you evaluate their completed Foldable.

Leveled Chapter Tests• Form 1 assesses basic chapter concepts

through multiple-choice questions and is designed for use with below-level students.

• Form 2A is designed for on-level students and is primarily for those who may have missed the Form 1 test. It may be used as a retest for students who received additional instruction following the Form 1 test.

• Form 2B is designed for students with a below-level command of the English language.

• Form 2C is a free-response test designed for on-level students.

• Form 2D is written for students with a below-level command of the English language.

Cumulative Standardized Test Practice This two-page test, aimed at on-level students, offers a page of multiple-choice questions and a page of free-response questions.

AnswersThe answers for the Anticipation Guide and Lesson Resources are provided as reduced pages with answers appearing in black. Full size line-up answer keys are provided for the Assessment Masters.

Ready

You will need:

3 index cards

2 different colored markers

SetWrite the numbers 1, 2, and 3 on index cards, one number per card. Place them facedown in a stack. Copy and enlarge the number line.

Finish Start

GO! 1. Give each player a different colored marker.

2. Have player 1 draw a card and start at 20. He or she uses the number on the card and says a subtraction sentence with the numbers; for example, 20 - 3 = 17. Player 1 circles the difference on the number line.

3. Place the card back on the bottom of the stack.

4. Player 2 chooses a card, uses that number and the last circled number, and says a subtraction sentence; for example, 17 - 2 = 15. He or she circles the difference on the number line.

5. Place the card back on the bottom of the stack.

6. The first player to get 0 as a difference wins.

Listening Assessment

Preparation: Counters and a 0 to 20 number line are needed for this activity.

Ask students to complete each of the following groups of tasks.

1. Use counters to show the number sentence 11 - 4 = 7.Use a second set of counters to show an addition fact related to the subtraction sentence.

2. Use a number line to show how to find the difference of 15 - 8 by counting back.

3. Use counters to show the subtraction sentence 16 - 8 = 8. Tell the addition sentence that is related to this subtraction sentence.

4. Use counters to show a subtraction sentence whose difference is zero. Use counters to show a different subtraction sentence whose difference is zero.

5. Use counters to show the subtraction sentence 13 - 7 = 6. Write the remaining number sentences in the fact family.

6. Use a number line to model the following pattern: 20, 18, 16, 14. Write the next 3 numbers in the pattern.
