I'm a new 7th grade teacher, and one of my classes is out of control. The kids talk over me, make jokes and laugh, get out of their seats, etc. I started writing their names on the board, and that quiets them down some, but there are so many talking it is hard to keep up. There are 34 kids in the class, and it is a small room, so they are right next to each other. My other 4 classes are fine (though they are not quite as big), but this one is driving me nuts! I looked at some of the Power Teaching websites, but it seems overwhelming, especially starting it now, a month into the semester. What advice to people have for me?
