These classroom debit cards are a great resource for keeping track of your classroom library, especially if you use a "READBOX."
Your kids will love it! They exchange their own, personal debit card for a book. The cards are numbered according to your students' class numbers. This way you know who has checked out a book from you and who hasn't.
When I used it, I had a bookshelf designed to look like a READBOX. My 6th grade students dropped their class debit card into a container when checking out a book from me. It worked great, and they loved using it.
There are 33 life-like sized cards total, numbered accordingly.
