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.
