I like to use a binder for my kids to checkout books from our classroom library so I can keep track of where certain books are and see how long they are holding onto books. It's also a great way to tell what types of books your kids are interested in!
-Binder spine for 1 in., 1.5 in., & 2 in. binders
-Student checkout form (print in B&W) to save on color ink
-Student number divider pages for 1-30 (I laminated to preserve)
-Student number tabs for 1-30 in alternating colors (I laminated to preserve)
