# Introduction

The Make It Real Learning Periodic and Piecewise Functions I workbook focuses on real-world situations that may be effectively analyzed using periodic and piecewise functions. This book is suitable for algebra 2 or precalculus students.

From determining whether it makes sense to do a credit card balance transfer to forecasting the hours of daylight at locations around the world, learners get to use mathematics in meaningful ways. Each activity integrates real world information, companies, and issues (e.g. Verizon, Disneyland, credit card balance, hours of daylight), 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.
