My students seem to need to go the bathroom all the time. I give each student a poker chip called a bathroom chip with the student's number written on it. I also make a chart of designated bathroom partners that changes weekly. Students may only use their chip once a week to go and they must take their designated partner of the opposite sex. If they don't use their chip during the week, then I give them extra tickets during our weekly reward time. If the child must go twice during the week then I keep their chip for the following week. I usually only have about five kids per week that need to leave the classroom.
