Eric Carle has written lots of books and some we had seen before but others were new to us. Here is a link to his website. http://www.eric-carle.com/home.html
Other teachers in the school and the school library helped us out with lending us more copies of Eric's books that they had, We love having more than one copy of a book so two or more kids can read side by side.
We finished the unit with one of his art techniques by making butterflies by dropping paint on one side of a wing shape and folding the paper to make the other side match. They made a great display in the hallway!
