WEEK ONE: Students used a plastic cup and watered down tempera paint to stamp circles on a sheet of white paper. Overlapping was encouraged. When finished, students moved to a clean table and used circle templates to draw faces, wheels, flowers, and more, just for fun.
WEEK TWO: Students colored in the circles with crayons. My example showed them how to overlap colors, but if they just had fun coloring, that was fine too.
