I saw this posted over at 36o and I thought it would be a really clever addition to the geometry section in Math for Elementary Teachers. However, I wasn’t crazy about the 1-minute introduction, which was obviously intended for a younger audience.

I figured that there MUST be a video on YouTube of **just** the song (about polygons, and featuring the nonagon especially) … sure enough … there is!
