I had an opportunity to take a step back and look at how I was doing and improve. I had a student in first grade who was misbehaving the whole morning, not doing any work, running in and out of the classroom and not being where he was supposed to be. One of the most difficult things about being a sub is not knowing the behavior reward/discipline system in the room. Even when the children try to explain it to you... you're talking about 20 six-year-olds trying to explain something to you and they can never all agree on the details of anything so my only real option is to throw kids who aren't listening out of the room and have another adult in the building deal with it.
Anyway back to the kid I started off talking about...
It was intervention time so some of the kids were in different classrooms and we were working in groups. This child was in my group, or he was supposed to be. He started off in the group but he had a pencil he kept playing with, we weren't doing any work where he even needed to write to I don't know why he needed a pencil. Anyway after a few times of telling him to stop playing with the pencil I asked him to give it to me. Every time I told him to do anything he looked at me like I was insane, I assume trying to figure out who I was telling him what to do. Anyway after asking him a few times to give me the pencil I told him to give it to me or go to the office. When he eventually came back from the office he was still not doing any work and misbehaving.
I told him this behavior was not an option and his choice was to take a seat in his chair or sit down with us and do his work. He was doing whatever he wanted and I told him I would call his Dad if he didn't stop misbehaving. When none of this was working I took a minute to redirect my approach since threats and force weren't working and really aren't a way I want to handle a child anyway. So I asked him why he wasn't listening or doing his work. He said because he didn't want to I calmly explained to him that this is school and not doing your work because you don't want to isn't an option so you can either make a better choice and rejoin the group and do your work or you can go and sit in your chair quietly. He came back to the group and did his work. I made sure to praise him for making the right decision and choosing to get his work done.
