Students of all ages are motivated to learn to think and work in 3D. They see it in movies such as The Incredibles and Chicken Little. They see it in television shows such as Max Steel and Jimmy Neutron. They see it in their video games. It is an integral part of their world. It makes sense, then, that they can be taught the essence of 3D graphics by letting them create their own 3D scenes. This paper presents a program called shapes. It allows kids of all ages to create their own 3D scenes that are interesting and compelling. By gently and subtly weaving Cartesian coordinates throughout the program, the kids learn about X, Y, and Z without even knowing they are learning it.
