Lights Out!

When the noise level gets too high in the classroom, sometimes doing a simple thing can make a big difference.

Just calmly walk over to the light switch and turn off the lights. When the class is quiet again, continue with your lesson in a whisper. (You can turn the lights back on in a couple of minutes.)
