C.H.A.M.P.S Chart classroom management posters. Each poster is a half of a letter size paper. This includes pointers that you could use to determine what level you are at per activity, you could also use a closepin.
In my class I hung them vertically with black ribbon glued to the back side of the paper. I put a magnet on the back of the pointers to go on my white board.
In addition, you could assign a student a job to move the magnets for you.
