Algebra Readiness Made Easy Grade 1

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 prob-

lem on the Problem-Solving Transparency. Then invite

children 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 writ-

ing about mathematics and may be used at any time. They are particularly effective when used

as culminating activities for the set of problems.
