This is a page of labels compatible with Avery 5160 address label size. I printed labels and placed them on the outside edge of each binder for the entire school year. For the ten Pre-K units of study such as Welcome to Pre-K, Five Senses, Water, Babies, etc, labels include the name of the unit, the themes, and titles of books for the unit. This helps me stay organized for every monthly unit at a glance. If you don't have labels, you can print on regular paper, cut and tape onto your binder.
