Using Glass Reflections to Your Advantage

Use reflections on glass doors to your advantage, you can see around corners when you are not seen.  If your classroom has glass on its door you can monitor the classroom when you have to step in the hallway to talk with someone.  I once proved my point to a class by standing behind a screen at the front of the room. They knew I could not see through it, however using the reflection on the door I was able to tell them what individuals were doing.  They were convinced I could see anything they did which helped improve behaviors in class.  (Just don't let them know about your secret tool)
