CIRCLES AND CIRCUMFERENCE

Circles are a very important part of our world.  Look around the room to find a circular shape.  We will name the parts of a circle and find its circumference.  We will explore a term called “pi” that is connected to circles.

Circumference is the distance around a circle.  Image being an ant and crawling around the edge of a circle.  When the ant reaches the point on the circle where he started, he has traveled the circumference of the circle.
