I have created a PDF file for labels I adhere to the plastic boxes that I use to organize my materials. See images below.
The PDF file is designed to print onto 8 1/2″ x 11″ full sheet mailing labels. The individual labels are then easily cut out using the guide lines. See images below.
You can organize your reading games using 4″ X 6″ clear plastic photo cases.
