Click the play button to watch the shape rotate 360 degrees. As it turns, count how many times it fits back onto itself (bottom box) to give its order of rotation (top box).After seeing the first couple, a class should be able to do the rest on their own, possibly as a test. Currently contains 14 shapes.
