Here is the latest addition to my room and classroom management repertoire. I found the idea on TheSchroeder Page, which I love (Thank you Monica!), and I immediately had to do the same thing. So far so good! the light is located right above my teacher/reading table. When I am meeting with a group, the students aren't allowed to "bug" us. We use the "ask 3 before you ask me policy," as well as the class question answerer trick, but lately we've need a little more reminding. The kids see the light and know to start problem solving.
