Light and Dark

I like this easy lesson for reinforcing color values, light and dark.

Fold square paper in half 4 times to end up with 16 small squares.  Then choose 8 different colored crayons, and color two squares with each crayon.  One square should be colored dark, and the other square is colored light.....depending on time, we also talk about using colors that are "warm/cool", "complementary", "analogous", etc.  You can make this lesson as complicated, or easy as you prefer.
