Amazing Pumpkin unit ideas...it has EVERYTHING pumpkin (science, literacy, music, art, dramatic play, math, etc). Check it out if you're in a theme based centre or if the children are interested in pumpkins in High/Scope. If you're in Montessori, well, I'm sorry but I have no idea if you could ever incorporate these. Like I said, sorry.
