## Reflection: Continuous Assessment Law of Sines Introduction - Section 1: Bell Work

As I moved around the room assessing students understanding I watched this student explain her reasoning to another student. I did ask her to explain her reasoning so I could tape the idea so the explanation in the video is faster than the original explanation.

This student has organization that helped her solve the problem. She is also able to communicate her reasoning which tells me she has a deep understanding of the problem.
