Review of polygons 
Opening: 
Yesterday we labeled a circle and talked about the radius and diameter. Today we will find the circumference. 
Direct Instruction: 
The circumference of a circle is the distance around the outside of the circle. It is kind of like finding the perimeter of a circle. To find the circumference, we use a formula. The formula is C=∏ x d. Pi is the ratio of the circumference of a circle to its diameter. It is equal to approximately 3.14.
If the diameter of a circle is 6, I would multiply 6 x 3.14 to find the circumference. If you are given the radius, find the diameter and then multiply by pi.
