I keep a binder near my library with these charts inside. Each student has their own chart in there (in order by their number, of course). Each time they check out a book, they add it to their chart. When the return one, they must put the date they returned it on their chart, and then highlight or cross out that book on their chart.
I've realized this makes it easier to see who is responsible for a lost book, since each student has their own chart to keep track of. I used to use charts where they would all write on the same one, but it was difficult to keep track of, and students would forget to go back and cross out a book they returned, especially if it was on a chart from a few weeks beforehand.
I recommend printing them back to back to save paper & space!
