For our opening in school every day, we watch a video about some interesting topic. Today we watched a Vi Hart video about Hexaflexagons. Basically the idea is that you fold a strip of paper into a hexagon, and because of the way it is folded, you can flip it so there are three unique faces to the hexagon.
The kids were quite taken with this, and after the pains of figuring out how to actually get it to work, this has produced days of entertainment and learning. Lots of geometry and patience is required!
There was also a renewed interest in art because to truly see the three different faces, you must color the three faces in unique ways.
