## Reflection: Flexibility Polygon Puzzle - Section 3: Sharing and Close

As we were closing the session today, one of the students asked what a 16 sided shape was called. I had no idea, be we looked it up on the computer as a class and realized it is called a hexadecagon.  I then asked the students to describe what that name made sense. Here is what happened.

As situations like this arise, I always get excited.  Not that the name of a 16 sided shape was in my lesson objective, but the fact that students asked the question in order to determine a solution, reasoned why prefixes and suffixes help us make meaning in math, and that there was true interest, justifies my belief that "in the moment" teaching and curiosity is crucial to a learning community.  It took 3 minutes longer than I planned for the lesson, but the outcome was worth 30 minutes!
