Need a way to limit the amount of times during your instructional time? I found a trick by using monthly restroom tickets. At the beginning of each month, give students a predetermined amount of tickets (3-5) that they can use as a restroom pass during class (independent work time only, not instructional time). At the beginning of the month, students should label their passes with their name and put these passes in a safe spot such as a teacher supplied envelope, pencil case, etc. During class, when students use a restroom ticket, with your final approval, they would sign out and drop this in the container on the way out, using one of their passes for the month. Of course, if a student has a medical issue or illness that allows them to visit the bathroom multiple times a day then this would not be appropriate for that child. It really works and limits the students who in the past would visit the bathroom three to four times a day. When we used these in my class, we had appropriate times during the day when students did not have to using their restroom ticket, such as beginning of the day, after lunch/recess, after or before specials, and at the end of the day. These restroom tickets I gave and required students to have was during instructional or independent time, but the way you use these tickets is up to you of course!
