I usse these passes as a Halloween Gift at the beginning of the month, instead of on Halloween. The students may use this pass to go to the restroom 5 times. They simply put the pass in the sand pail and go to the restroom. They don't say anything, so they are not interrupting a lesson or small groups. I punch the highest number first, so they can know how many times they have left to use the restroom. If they need more visits to the restroom, they they have to purchase a new card using classroom money they have earned. To know more about that, you can visit my TpT store to learn more about my Classroom Economy from an older "post"
