Teen Pregnancy: Investigating Cubic Functions
The Make It Real Learning Polynomial, Power, Logistic, Rational Functions I workbook focuses on realworld situations that may be effectively analyzed using polynomial, power, logistic, and rational functions. This book is suitable for high school or college level algebra 2 or precalculus courses.
From monitoring changes in height and weight to forecasting the population of Michigan, learners get to use mathematics in meaningful ways. Each activity integrates real world information, companies, and issues (e.g. Europe, Michigan, Social Security, teen pregnancy, gaining weight, growing 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 classwide discussions.
As a readyresource for teachers, the workbook also includes completely workedout 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.
