## Reflection: Developing a Conceptual Understanding Exploring Circumference - Section 2: Explore

This was a very cool activity! Students were excited about doing the actual measuring to generate their data. It wasn't difficult for them to determine that there was a connection between the two. Determining what that connection was took a little more time. One change I may make for the next time I do this activity would be two offer two different colors of yarn to each group. They can use one color for the circumference and one color for the diameter. That might make the connection easier to see.

Do you see the connection?
