These cards were made to keep all student AR passwords in one place. There is also room on each card to write their reading levels for each quarter as a quick place of reference for students to look to make sure that their books are a good fit for them.
For best use, laminate and cut out individual cards. In my classroom, I have all student password cards on one binder ring and on a command hook next to our student computers.
Feel free to ask any questions that you may have!
