The inspiration for this activity is the mathematics videotape Donald in Mathmagic Land, originally produced as a movie by the Walt Disney Company in 1959. Anticipating current music videos and some commercials, the images are tantalizing and rapid, encouraging some teachers to show it to students as early as third or fourth grade. The mathematical presentation, however, is deep and brilliant, so I had a natural desire to slow it down and make it truly accessible to students. I generally show the videotape to students just after we complete the exercises presented in this article, and several have told me that it was the third or fourth time they had seen it but the first time they understood it.
