More specifically for the exercises, (repeating from my FB comments):
The fun of it was also in the exercises. I asked class to color up 2 quarter sheets using black crayon. Freehand cut a couple circles, several elongated teardrop shapes of varying sizes. Make an arrangement on a blank quarter sheet using several shapes. Draw this arrangement on other blank quarter sheet. Look at your drawings and see if you can find a figure or whatever in them. Now try to make an arrangement that is somewhat like an action sports figure, preferably winter sport. This will be quite abstracted. Now see what kind of penguins you can make from your shapes, (and draw). None of these drawings should use outlines. They should be done by coloring out/up/in(?) the shapes.
