Algebra I with TInspire Semester 1 Author:Brendan Kelly 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 o... more »f exercises with complete solutions are provided. Screen displays enable students to connect their work 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 understand how to use graphs, spreadsheets and the calculator commands to solve real-world problems. The 32 Explorations in this text are as follows: Topic: From Arithmetic to Algebra 1. The Natural Numbers (primes and composites) 2. Greatest Common Denominator and Least Common Multiple 3. From Integers to Fractions & Real Numbers 4. Unknowns & Variables: Entry into Algebra 5. Computing with Mathematical Formulas 6. Formulas and their Inverse Formulas Topic: Linear Equations & Inequalities 7. Using Tables to Solve Linear Equations 8. Using Algebra to Solve Simple Linear Equations 9. Using Algebra to Solve Compound Linear Equations 10. Solving Proportions 11. Manipulating Formulas by Solving Equations 12. Linear Inequalities in One Variable Topic: Functions & Relations 13.
