I finally have a bathroom pass situation that totally works for me. Take the printables below (or create your own) and tape them to GIANT bottles of hand sanitizer. When they have permission to use the restroom, they put the sanitizer on their desk. This serves two purposes; I can quickly look at their desks and see that they're in the bathroom and they get a squirt of hand sanitizer when they come back. We need all the germ fighting weapons we can find!!!
* Ericka has her kids use the bathroom sign to ask to use the restroom. Works great for times like guided reading when you do NOT want to be interrupted.
Here are the handy dandy printables
