I saw this project on teachpreschool.org. It is making leaf prints using cut up egg cartons. I just drew a tree with branches (yes, I realize that anyone else in the world could draw this better than I did) and set out some red, brown and yellow paint for Mercedes. We talked about how in the fall the leaves change from green to red, brown and yellow and fall off the trees. This is why Mercedes chose to paint most of her leaves at the bottom of the tree. She kept saying "leaf fall down, leaf fall down." She loved this. I think we'll have to do another one with green leaves in the spring.
