Not Spirograph
I loved Spirograph when I was a kid. I bought this for my children, but it never worked right. Do not waste your money on this product. Get a compass and a straight edge. You will have more fun. There is a book called "Creative Constructions" that I use instead. Even my math students love the creations that they can make using the basic constructions skills I teach them like bisecting line segments and angles, then turning it into art.
