Introduction


This lesson teaches students how to make circles using given radii. It also teaches the precise definition of a circle: the set of all points that are a fixed distance (called the radius) from a given point (called the center). In “kid-friendly” terms, a circle is a bunch of dots that are all the same distance away from a middle dot.


The Project


Students will make five circles with radius lengths of 4 cm, 5 cm, 6 cm, 7 cm, and 8 cm. They should start by making largest circle and work their way down, using five copies of page 155. The teacher should model how to use a ruler and pencil to make circles.
