Activity Overview

The primary focus should be on slope as rate of change and piecewise functions. This activity allows exploration of multiple types of slope; i.e., positive slope, negative slope, or zero slope for students to build their understanding of varying rate. This activity also allows for exploration of intersections of linear functions leading to an understanding of solutions to systems of equations. There is no one correct answer to this activity and students should focus on what conditions determin

Before the Activity

See the attached PDF files for detailed instructions for this Activity.

Print the appropriate pages from the Activity for your class. Install the MathWorlds Application on the students' graphing calculators following the instructions in the Activity overview.

During the Activity

Distribute the student activity pages to your class. Distribute the MathWorlds AppVar file to your class using TI Connect and the appropriate TI Connectivity Cable.

Follow the procedures outlined in the Activity.

Students will:

  • Understand slope as rate from a qualitative perspective
  • Write stories that are mathematically expressive

  • After the Activity

    Review student results:

  • As a class, discuss questions that appeared to be more challenging.
  • Re-teach concepts as necessary.
