About this book

This book focuses on algebra as a language of process, expands the notion of variable, develops ideas about the representation of functions, and extends students' understanding of algebraic equivalence and change. In the activities, students apply properties of functions by using median salary data, explore the meaning of equivalent equations, and use recursive or iterative forms to represent relationships. The supplemental CD-ROM features interactive electronic activities, master copies of activity pages for students, and additional readings for teachers. - Publisher.
