INTRODUCTION

Using the Transparencies

In addition to the reproducible problem sets, you’ll find ten overhead transparencies at the

back of this book. (Black-line masters of all transparencies also appear in the book.) The first

six transparencies are reproductions of the “Make the

Case” problems, to help you in leading a whole-class

discussion of each problem.

The remaining four transparencies are designed to be

used together. Three of these transparencies feature six

problems, one from each of the problem sets. Cut these

three transparencies in half and overlay each problem on

the Problem-Solving Transparency. Then invite students to

apply our three-step problem-solving process:

1. Look:What is the problem? What information do

you have? What information do you need?

2. Plan and Do:How will you solve the problem? What

strategies will you use? What will you do first? What’s

the next step? What comes after that?

3. Answer and Check: What is the answer? How can you be sure that your answer

is correct?

These problem-solving transparencies encourage writing about mathematics and may be

used at any time. They are particularly effective when used as culminating activities for the set

of problems.

What is the cost of Tiny’s phone?

Use the facts to figure out the costs.

FACTS:

A) Tiny’s phone costs the total cost of Sara’s and Tiptoe’s phones.B) Sara’s phone costs $6 more than Tiptoe’s phone.

CD) Paul’s phone costs $30 plus the cost of Dumbo’s phone.) Tiptoe’s phone costs $18 plus the cost of Paul’s phone.

E) Frosty’s phone costs $42.
