Published on 04/18/2005

#### Activity Overview

Lesson 8-1: Exploring Exponential Models is from Chapter 8: Exponential and Logarithmic Functions. Choose a Model from the TI-83/84 Plus Activities booklet accompanies this lesson.
Students will model exponential growth and model exponential decay.
Students will make a visual choice of an appropriate model and then use the Transformation Graphing App to confirm their choice.

#### Before the Activity

If you are using the TI-Navigator System with the TI-73 you will need the attached .pdf file.
Review the lesson PDF files.
Make copies of the lesson PDF files for your class.
Using LearningCheck™ Creator review the LearningCheck EDC files prior to class. They include the Diagnosing Readiness,Check Skills You'll Need, and Check Understanding questions from the lesson.
Make sure LearningCheck and Transformation Graphing are on all student calculators.
Transfer the LearningCheck EDC files and the Program File to student calculators using one of these methods:

• TI Connect™, a connectivity cable and unit-to-unit cables
• TI-Navigator™ "send to class" feature
• #### During the Activity

Students will:

• Model exponential growth
• Model exponential decay

• Directions:
• Distribute the student activity sheets
• Follow the procedures as outlined
• #### After the Activity

As a class, review student answers, discussing questions that appeared to be more challenging, and re-teaching as needed.
