Introduction

The Make It Real Learning Linear Functions I workbook focuses on real-world situations that may be effectively modeled by linear equations. This book is suitable for both algebra 1 and algebra 2 students.

Whether choosing a cell phone plan or downloading music, learners will discover how to use linear functions to help them become better informed consumers. Each activity integrates real world information, companies, and issues (e.g. Yahoo!, T-Mobile, life spans, WIC, making money), not just "realistic" data.

There are multiple ways to use the activities of the book in a teaching environment. The activities are an excellent tool for stimulating mathematical discussions in a small group setting. Due to the challenging nature of each activity, group members are motivated to brainstorm problem solving strategies together. The interesting real world contexts motivate them to want to solve the problems. The activities may also be used for individual projects and class-wide discussions.

As a ready-resource for teachers, the workbook also includes completely worked-out solutions for each activity. To make it easier for teachers to assess student work, the solutions are included on a duplicate copy of each activity.

The PDF for this book is enabled for annotation. This means that if you prefer, your student can fill it in on the computer, using the typewriter and drawing tools in Acrobat Reader version 9 or greater.
