## Reflection: Grappling with Complexity Circles and Parallelograms - Section 2: Explore

This activity provided a lot of anticipation. With the recent activities we had done to establish connections, I think the kids were excited to see what we would come up with this time. I don't think they had imagined establishing a connection between circles and parallelograms. They did really well with the completing the steps in the activity so they could make the connection between the diameter and the base of the parallelogram.
