Circle Equations

Published on 08/24/2005

Activity Overview

Students will practice their knowledge of circle equations in the y= form by matching equations with pictures of various circles.

Before the Activity

Teachers need to teach students the equation of a circle in vertex form, then show students how to manipulate this into the y= format, reminding them they must enter the top and bottom of the circle separately. Read Equation of a Circle.doc for teacher instructions for practice writing equations.

During the Activity

Have students go into activity center. Teacher opens Circle 1.act and runs the activity. When this activity is complete and answer is verified, repeat with Circle2.act and then Cirlce3.act.

After the Activity

Review student results:

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