## Reflection: Modeling Revising Mathematical Explanations - Section 1: Opening

After teaching this lesson, I was introduced to this great video: Austin's Butterfly: Building Excellence in Student Work - Models, Critique, and Descriptive Feedback.

Several teachers in my district showed this video to teach the concept of precision and to teach students how to give constructive feedback.
