Middle Grades Math: The Variables of Renting

by Texas Instruments

Overview

In this activity, students will identify what a variable is, construct a table of values, graph the ordered pairs from the table, and use the TI-84 Plus C Silver Edition to graph the equation.

Key Steps

    Students will identify what a variable is, construct a table of values, graph the ordered pairs from the table, and use the TI-84 Plus C Silver Edition to graph the function. First, students look at the video rental rates using number sentences.

    Then, students graph the scatter plot of ordered pairs and look at the line that passes through all the points.

    Finally, students analyze the table of function values generated from function representing the video rental scenario.
