I don't have a self-contained classroom, but I still wanted to be able to efficiently post Centers for my 90 students. Each row is for a different class, with an envelope for the assigned center. The sticks have my student's names on them, which makes for quick and easy movement.
Once students enter the room each day, the timer begins. The timer stops once lunch count/attendance is taken on the Smartboard, everybody's materials are out on their desk with their binder underneath the desk, and everyone is seated. Sixth grade students love competing to beat their previous time. The best part? I don't have to say a word. My students encourage everyone to follow expectations and get ready to go as fast as they can.
