This Instructional Activity is a part of the Lesson 5, Unit 3, Grade 7. Students measure the circumference of circles by rolling them like wheels. They relate this to what they previously learned about the relationship between the diameter of a circle and its circumference. The circular objects that students measured earlier can be reused for this activity, the difference being that rather than wrapping something around each circle, they will roll the circle on a flat surface in order to measure its circumference.
