My substitute started this lesson with the 3rd grade classes while I was gone and I finished it up after I got back.
She first taught them a lesson about color where each student made a color wheel and then learned about different color schemes: triadic, complementary, warm/cool colors and monochromatic. Next each student needed to come up with 5 symbols that represented things about themselves they wanted to share. They drew their symbols on the coat of arms template and then chose one color scheme to paint their coat of arms. This is just another great example of how color is so powerful!
