Reflection: Relevance The Quilt Code: A Lesson in Triangles Through History - Section 2: Defining Right Triangles


I really think this little exercise is one of the most powerful because I saw students using their arms later to think through what angles they were naming. Just standing up and using our arms to define the angles engages the brain, gives students a visual because they remember what what they did and what they saw at the same time. I love it!
