Over the summer at garage sales I look for little baskets, crates, organizers. As my class learns the letters of the alphabet, in class we create a basket for that letter (A-Z) and make a big label for it. Then they hunt and find titles of our books to "live" there for the year. It teaches many skills as the kids love to "spy" the books. Example: "Corduroy" would go in the "C" basket.
