Fall Leaves Scene is fun to make with ages 5+
2nd- Draw and then cut out your tree, either black (for higher contrast) or brown (realistic). I made this example for the kids at my daughter's 2nd grade class, and the majority of the kids chose to make a brown tree.
3rd- Then cut the Fall colors page into triangle-shaped pieces for the leaves and glue/paste onto the other page. You can get creative and involve wind blowing them around... falling off the tree... piling up so high... whatever you like!
Unfortunately I don't have any of the kids' creations right now because it snowed the day we were going to finish them and they closed school for the following 3 days! Hopefully they will finish them in class and I can take pictures of them. The trees were so wild and fun!
