Classroom Management

In my kindergarten class this year I had a little girl who had to use the restroom. She is a very patient girl who always follows the rules. I had asked the class a question about the activity we were going to do and many students had their hands in the air. When I called on her several minutes later, she asked if she could use the restroom. I felt badly that I had made her wait that entire time. With students that age it could have been too late for her. After thinking it over, I decided to teach the kindergarten class the sign for toilet and if they need to go now, instead of just raising their hand, I have them do the sign so I can distinguish it from the other questions, comments, or stories.
