I recently talked about angles in a triangle with my younger son. For today’s discussion I thought it would be fun to talk about angles in polygons. My son had some absolutely lovely ideas. It is so fun to hear how a kid thinks about a topic like this one.

Sorry this is a little longer that usual – 7 minutes instead of 5 – but if you are interested in hearing kids talk about math I think you’ll like this talk a lot.

Cool. It was interesting to see the jump from quad to pentagon. Took a more circuitous path than I would have expected. And then the jump from 5 to n was quick! Did you throw some concave polygons at him yet?

Wasn’t one of his pentagons concave? (I might be confusing the video with something that we did off camera, though)
