Published on 06/09/2008

Activity Overview

In this activity, students learn to calculate the area of geometric shapes. They solve real world problems involving area.

Before the Activity

  • Install the Area Formula App application on the calculator using the TI Connect™ , TI Connectivity Cable, and Unit-to-Unit Link Cable

  • Set up the calculator as explained in the appendix
  • See the attached PDF file for detailed instructions for this activity
  • Print the pages from the attached PDF file for the class
  • During the Activity

    Distribute the pages to the class.

    Follow the Activity procedures:

  • Determine the area of the plot and the cost of the plot
  • Calculate the square feet of tile required to tile the shaded area


  • Select the triangle option on the application to find the definition and formula for area of a triangle
  • Calculate the area of the shaded portion using the formula
  • Find the area of other shapes
  • After the Activity

    Review student results:

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