Reflection: Trust and Respect Foundational Circles Vocabulary and Chord Properties - Section 3: Connect Two: Circles Vocabulary


I wanted to hold students’ accountable for making sense of the definitions of our new circles vocabulary.  For this reason, I told students that in the debrief of this activity, I would randomly call on them to share out about a connection they had made.  I instructed them to listen carefully so that each newly called on person would share out a new connection that had not previously been shared.

What was fascinating to me in the debrief of this simple “Connect Two” activity was the way in which hearing about the connections between the vocabulary words helped to unearth misconceptions and develop layers of understanding.
