Organize your book library by reading level. Use stickers to designate the different levels by placing them on the books. This is a good way for you to enable the students to easily select books at their reading level. Make a chart indicating which reading level corresponds to the colors and post it close to your book collection. Use level names that kids can identify with: Rookies, Aces, etc. Alternatively, organize your classroom library by author combined with reading level. Cut cereal boxes diagonally from top corner to half way down on other side. Write letters on the cereal boxes and have reading levels marked on them. Put books into the boxes that correspond with the markings and have the book names written on the edge of the cereal box for reference.
