The lesson plans in this book engage students by using a tool they enjoy--the Internet--to explore key concepts in algebra. Working either individually or in groups, students learn to approach algebra from a problem solving perspective. Each lesson shows learners how to use the Internet as a resource for gathering facts, data, and other information. Topics addressed include functions, graphing, equations of lines, correlation, regression lines, unit conversion, estimation, quadratic functions, rate problems, percent change, and the Pythagorean theorem.
