## Reflection: Developing a Conceptual Understanding Rainbow of Angles! - Section 2: Concept Development

As you can see in my video reflection, using manipulatives worked excellent in this lesson. I have never used wedges and circles like the ones in this lesson before to teach angles. In pre-Common Core standards, much of my emphasis with angles was only on how to use a protractor.  I failed to give my students such important information about the relationship between circles and angles. This lesson was a huge success and most definitely set my students up for being able to use a protractor successfully in future lessons.
