Students will measure the circumference and diameter of several round objects. Then students will use Cabri Jr.™ to construct the diameter of a circle and measure the circumference and diameter of the constructed circle. They will send in their measurements using the TI-Navigator Activity Center and discover the relationship between the circumference and diameter.
Before the Activity
See Roundup TI.pdf for step-by-step instructions.
After the Activity
Attached is a LearningCheck™ that you can use to assess student understanding of the relationship of circumference of a circle to pi.
