Fifth Grade Optical Illusions

I saw a similar project to this online and decided it would be a successful project for my fifth graders. They had to use a cool color on their hands and a warm color on their background. This project went pretty quickly and was a good first project that everyone was successful with. It was a great reminder about overlapping, as well. They loved looking at different examples of optical illusions each week and I shared some of M.C. Escher's work too.
