Are you sick of students always asking to go to the bathroom in the middle of your lesson?!?!?! I am so tired of this! So I made a simple solution! A sign that is right next to our Smart Board. I simply flip the sign before we start a lesson to say "Bathroom is closed". If a student asks to go to the bathroom I simply point to the sign as a reminder that they cannot go. Students will build the habit of noticing the sign before they even ask to go to the bathroom. This is something so simple yet effective.
Think that you will forget to always turn the sign over or think it will be just one more thing to do?! Let your student teacher assistant be in charge of the sign! We build this routine into the student jobs and it becomes one less thing for me to do! It a clear reminder of when it is an appropriate time to use the bathroom and when it is not.
I hope this works out for your students like it did mine!
If you see a combination of designs that you would want and I did not make, please send me an email (firstname.lastname@example.org) and I'll be happy to make it for you! =]
