1. Each student is given a large sheet of paper, 11" x 17" or so, and a thick black marker. Following my sample on the board, I have them draw a zig-zag line from edge to edge across the paper. Then, they add a loop-de-loop, a wavy line and a straight horizontal line. 2. They then draw one straight vertical line and one diagonal line, wherever they like. The result is lots of closed spaces to fill with color. 3. All spaces are to be carefully colored in.
