Butterflies, bats, blue, brown, black, and beach.
I figured the best way to learn about the beach was a field trip. Here is A washing some of the huge sea shells we collected and brought home. His favorite are the 'butterfly shells'.
This is a beach collage we both worked on. A did his pretty much all by himself. (I mostly pointed, he did the action.) Materials: torn construction paper, sand, shells, blue watercolor, and glue. It's a masterpiece.
