Approximation of Pi

Activity Overview

Students will measure the circumference and diameter of a variety of different circles. They will graph the class' values of (d,c) on the coordinate plane and use linear regression to approximate pi.

Before the Activity

I assign students the task of bringing in a circular object. Items such as CD's, coins, large spools or lids.

During the Activity

Please see the attached document for detailed instructions.

After the Activity

Review student results:

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