Reflection: Checks for Understanding Exploring Circumference - Section 3: Landing

This exit ticket made me happy. They do understand what the circumference is. One of the ways a students gave to remember was that she didn't have to square to go around a circle. I appreciated the idea that they had their own ways to differentiate between the two formulas that went beyond memorizing. Most of my students showed that they understood.
