Students used a real leaf as a pattern to draw their own leaf in pencil. Then I had them put a small dot in the center of the leaf. Next, I showed them how to use a ruler to draw straight lines connecting the dot to all the points on the leaf. This gave them areas to paint in. It also gave them some much-needed practice using a ruler. Using small brushes, students were instructed to paint a different combination of warm colors in each section. We used red, orange, yellow, brown, and a little green. To avoid the paint all running together, as watercolor does, students skipped sections to allow each to dry a bit. Then they went back and painted the rest. Some studetns had time to paint a cool-colored background - purple and blue.
This website is where the idea came from for this project.
