## Description

While supplies last.

This book is designed to help teachers implement the marvelous power of TI-nspire in the teaching of Algebra I. Keying sequences are provided to help students acquire the concepts of elementary algebra in a step-by-step fashion, while progressing smoothly through the menus of this exciting new technology.

Worked examples and comprehensive sets of exercises with complete solutions are provided. Screen displays on the page enable students to connect their work on the handheld or on the computer screen to the examples in the text.

On completing this book, students will have been exposed to all the important concepts in the first semester of Algebra I and will have had numerous experiences using graphs, spreadsheets and the calculator commands to solve real-world problems.

The sequel to this book, Algebra I with TI-nspire: Semester 2 is also available. Together, these two books constitute a full program in Algebra I as defined in all the US state guidelines. Both the pedagogy and content have been developed to implement the underlying philosophies articulated in the NCTM Principles & Standards for School Mathematics.
