I created these because I was facing a "we-all-need-to-go-at-the-same-time" kind of restroom challenge. I give students 2 to 3 of these per week. They can use these passes any time should they have a restroom emergency! They raise it up in the air, and I dismiss them to go. They place their passes in a little container on their way out the door. At the beginning of the next week I pass them out again. The majority of students rarely use all 3 of them.
I print the passes, write the students' numbers on them, and then laminate them. Then I cut them and hand them out.
It has cut down tremendously on restroom visits!
