I have a white board that the students sign-up on when they need to use the bathroom. The top person on the list goes to the bathroom. When they return, they erase their name and the next person goes. We have gone so far as to have them write the time that they leave the room as well (which practices telling time) and for some that works as a deterrent and they only sign up if they really need to go.
