I use these door hangers in my classroom for easy bathroom management. Students simply flip to the STOP side if they are entering the bathroom, and flip to the GO side when they are exiting. The clear stop and go visual cues make it easy for non readers to know what action to take. You can glue both sides together to make a reversible door hanger, or use only one side. It's as easy as printing, cutting, gluing, and laminating!
I hope you found this resource useful for your classroom!
Please let me know how I can improve if necessary.
