That's what we have done at our school. My children are the "middle" kids (3&4) but each class participates at their own level. Even the children in the 2 year old class are enchanted by the life cycle! It's a great way to foster collaborative learning. Does your school participate in Journey North and the Symbolic Migration? http://www.learner.org/jnorth/sm/index.html
It's a great project! It's supposed to be for K and up. But we participate (enthusiastically) at our own level!
I was given that book as an end of year gift.. And now you have given me the motivation to take it to the beach to read!
And I love all of the Smithsonion books for kids..especially Monarch Butterfly of Aster Way. The children love it so much that I scanned the illustrations in the book to make a board game for the math center.
It's my dream to go to the sanctuary region.How awesome that you were there!!! Do you have pictures you could post? (Although I know that photos would never capture the real experience!)
