I thought I might post how I organize all the index cards that we put with the iPads. I bought these cute little boxes at Target last year thinking that I would use them in my classroom. Since I'm obviously not in there right now, I thought we could use them to store each grade level's index cards.
Each card contains the serial number of the iPad, the Desiny Number for checking it in and out of our library, and we wrote the student's name on the back of each card.
This really is a SUPER easy way to track all the iPads, have immediate access to student serial numbers and find any information that we might need.
