The 7th grade teacher I covered on a Friday and Monday a couple weeks ago had a meeting 4th period, and by sheer luck I was sent to cover her class on my prep. The kids seemed to remember me, calling me by name even though I didn't put my name on the board.
When I got there their teacher was going over instructions. The room was silent. Then they got to work and the room continued to be silent. Then the teacher left.
"Can I go to the bathroom?"
Then five students needed a dictionary, three others needed to sharpen their pencils, and the boy over in the corner reminded me why the story about the teacher who duct taped a student to his chair wasn't such a horrible idea. And I got several questions about the assignment--questions I could answer because I had been listening when the teacher was giving directions.
I wasn't in there for the full period. I had them for about 40 minutes. They got louder and louder. I shushed them, but that didn't work for long.
Then their teacher returned. She barely said anything to me as she took back over. "Put your books and everything away," she began. She sounded angry.
They knew she was returning. So, they did it to themselves.
