I was going to post this in the Substitutes forum, but it seems most threads there revolve around issues such as pay and such. My question is on classroom behavior and techniques to keep things on an even keel. While many of you are not subs, perhaps there are some things you have used when new to a room that might help. Yesterday I was a sub at an urban elementary school, subbing in a 7/8 learning support room. At noon I was asked to take a Gr 4 room - the kids were literally waiting for me to get them from lunch, so there was zero prep/consultation with the room teacher. Things went south pretty quickly. They did not follow instruction from the teachers monitoring the hallway and having no idea who I was did not take too readily to directions from me. I had good support from the other teachers and in fact one of the other LS teachers spent the rest of the afternoon with me and one other teacher in the room - it seemed no one could get these guys to settle down. We had essentially the same behavior when the rooms switched (there are 2 Gr 4 classes). I was told later that this has been a really rocky week and that no one was really sure why. Behaviors were: talking out, wandering, refusing to respond to directions. I don't know if, or how many students are on IEPs/behavior plans in the rooms. It was classic brushfire: once things started in one corner it spread across the room. We did get some things accomplished so it was not pandemonium. What I am looking for are things that I can do to set a tone from jump so that things don't get out of hand next time... Thanks!
