I don't know about your students, but my students are constantly arguing over who was next to take an A.R. Test or go to the library. So I created an A.R./Library line. If students want to take an A.R. test or go to the library they take their number and move it to the line. Or you could just use the numbers for something completely different. My classroom theme is a super hero theme so I created them to look like something from a comic book. Enjoy! Please let me know what you think.
