I have done this project many times with my grade 11 art students. Students design a sinsgle 30 degree wedge, and then transfer that design 12 times to make a large pie/wheel. Students then complete the colour/color wheel with paint. Students must mix all the secondary and tertiary colours, as well as the tints and shades. It takes a while to finish, but the end result is always very eye catching when they are displayed.
