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.

Rainbow of Angles!

Unit 9: Geometry
Lesson 2 of 11

Objective: SWBAT explore angles and their measurements using 360 degree circles and parts of circles to make sense of benchmark angles.

Big Idea: In this lesson, students use fraction circles and an interactive smart board program to explore angle measurements as part of 360 degrees of circles.
