This is a lesson that I have done with my first graders. As a class, we look at and discuss aboriginal art, and then I give them a piece of paper, and have them trace their hands with a pencil, three times. I want them to overlap the hands. After the hands are drawn, I give them black sharpies, and have them trace over their pencil lines. Next, I talk to them about patterns, and then give them colored sharpies and the students draw patterns on the hands. Finally, the students pick a color to paint the background. I really like to use opalescent paints for the background, it gives the pictures a little shine.
