What Goes Around Comes Around - But Can You Measure It? (Perimeter, Area, and Volume)

Published on 06/09/2008

Activity Overview

Students find the area and the perimeter for several geometric shapes. They also determine the surface area and volume of spheres.

Before the Activity

  • See the attached PDF file for detailed instructions for this activity
  • Print pages 106 - 108 from the attached PDF file for your class
  • During the Activity

    Distribute the pages to the class.

    Follow the activity procedures:

  • Divide an irregular geometric shape into rectangles and right triangles
  • Calculate the perimeter and area of the shape
  • Use the calculator to find the length of a missing side, given the measures of other sides in a figure
  • Repeat the steps for different figures

  • Use the correct formula to compute the surface area and volume of a sphere
  • Find the surface area and volume of objects in the solar system
  • After the Activity

    Students complete the Student Activity pages.

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