## Reflection: Modeling Mini Golf Mystery - Using a Protractor - Section 1: Warm Up

I was so happy and surprised with the way a student volunteer explained how to use a protractor.  I expected her to talk about lining the edge of the protractor up with the angle ray.  She didn't. She said that was one way to use the protractor, but then she very eloquently talked about that she could use both numbers because when measuring angles, you are measuring the degrees in reference to a circle. I was so impressed and super excited that students are realizing this importance.  This is something I have never emphasized pre- Common Core, but am so happy I have changed my lessons in order to build students conceptual understanding of  measuring angles.
