Note: Each procedure you teach must be modeled, talked about, practiced and reviewed.
It might go something like this:
Step One: It you need to use the restroom show me R for restroom hand signal. Teacher shows students.
Step Two: Let’s Practice. What do you do if you need to use the restroom? Students respond with hand signal.
Step Three: When you walk to the restroom should you be talking? Should you hang out in there or come right back? How do you re enter the classroom?
Step Four: Review. What is the bathroom procedure?
You may find that digital agendas like these help you give visual reminders to students.
