Introduction
The Make It Real Learning Exponential and Logarithmic Functions I workbook focuses on real-world situations that may be effectively modeled by exponential and logarithmic functions. This book is suitable for algebra 2 or precalculus students.
From determining whether it is better to take a low interest rate or cash back to forecasting the cost of living, learners get to use mathematics in meaningful ways. Each activity integrates real world information, companies, and issues (e.g. Chase Bank, GMAC, DVD sales, compound interest, shopping center planning, cost of living), 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.
