Decomposing shapes

This is a teaching keynote on decomposing shapes. This is based on the 6th grade math TEK 6.8B model area formulas for parallelograms, trapezoids, and triangles by decomposing and rearranging parts of these shapes.

Thank you for this awesome share. I am sharing this with my math department so they can integrate an artifact like this.

I love the animations that you have added to really show how these area formulas are generated from known shapes! That is going to help students be able to recall those formulas, or generate them on their own if they can’t remember. Thanks for sharing!

Do you use this just for your lecture, or do you have students create their own? You could have them add an audio recording explaining it! They could even export it as a video and then use iMovie to add in sound effects to go with the shapes moving or being cut!
