We read "Red leaf, yellow leaf" by Lois Elhert and the made these beautiful fall inspired collages. The first step was the background, which we did through a technique I developed that I call "collaborative art". Each child starts with a piece of paper and then rotate, until everyone has draw on every piece of paper. Later we added the painted leaves, grass and pumpkins. I developed this lesson for children ages 2-4 at Kids in Bloom preschool alternative in NYC.
