I use this paper for keep track of student bathroom trips. I copy this on colorful paper and cut it into 2 sheets. Students glue these in the back of their interactive notebooks. When they want to go the the bathroom they bring the notebook to me so that I can initial and date in one of the squares. They have 3 bathroom passes each 6 weeks. They are not allowed to go if they don't have their notebook or if the squares have been used. At the end of the 6 weeks I give bonus points to the students that do not use their passes.
