## Exploring Linear Relationships -- Stacking Cups and Walking Rates

#### Activity Overview

In this activity, students will explore several examples of linear relationships. They will use a table to organize data that they collect and will make graphs to display that data. Students are prompted to write equations and interpret slope as a rate of change.

#### Before the Activity

Download the files for the activity and read through all materials. Distribute the TNS file to students and make copies of handouts as needed.

Pass out stacks of cups to students as described.
