Draw 160
The class of 10 drew 160 images in about 5 minutes. How it works: you would get the cartoon grid and read all 16 of the boxes. Pick your favorite to draw and then, when finished drawing, pass it to the left, to the next student cartoonist. The 10 pieces of paper went around the circle of hardworking cartoonists until all of the grids were filled in.
I think I would love to try this exercise with a group of artist. It’s been some time since I was in a classroom and I don’t expect to be in one soon, but at my next brainstorm meeting I think this would be fun to try.
