## Reflection: Debate Adding up Angles - Section 3: Concept Development

This problem solving approach, which involves students being out of their seats, is a great way to keep students engaged in and talking about mathematics. At this time of year, I have found that I need to have my students partner work and group work very structured.
This activity helps keep students organized, motivated, and on task during the group discussion time.
