I found these great mini accordion books by Ruth Bleakley at ruthbleakley.com and I knew they would be perfect for our project. We used maps from the great USA to cover the front and back cover of our books.
The best piece was tying it in to our literacy part. Todd Parr and a fabulous little simple book called The Peace Book. The illustrations are bright and cheery and I love the simple text. My students created their own Peace Book and we are in the middle of finishing the books up this week.
