First period went really well. I wasn't surprised. This teacher's classes tend to behave (even though this is the continuation high school). Then second period arrived.
I had been warned to make sure that the students sat in their assigned seats. So, when three boys took up spots in the tables at the back of the room, I knew something was up. The seating chart had no one sitting there.
When called on it, one boy informed me that Ms. W. I had told him he could sit back there. Sure, yesterday, maybe. No, he explained that he asked her yesterday if he could sit back there today. I reminded him that Ms. W. was not in class today, so I needed him to sit in his assigned seat. He was having none of it.
Before I determined my next step (referral?), security walked in. He was looking for a student who was not on my roll sheets. But before he had a chance to ask the question, the boy scrambled back to his assigned seat.
Interesting how he could be so belligerent with me but compliant the minute another adult stepped into the room.
I should be used to this by now. It's how most students treat the sub.
For the rest of the period, the boy worked. Quietly and diligently. Other students would say "Security!" and that would get him to look around, but other than that, the period was unremarkable.
I don't know what it is about having a sub that makes students try to get away with things. Did you ever try to get away with something with a sub? What was it, and did you succeed?
