Can I just say that I appreciate my class more when other classes have a substitute? Yesterday, the class next to mine had a substitute. Bad is not an appropriate word to describe that room. Out of control would be a better description! By the afternoon I couldn't take it anymore. I just stood outside the door and glared at the students. They quickly got quite and sat up in the chairs. I went back in my room laughing at how a look can make such a difference. Have you mastered your look?
