Hello! I recently started a two week long term sub position, and I am really struggling with classroom management. I'm a new teacher, I graduated in 2016 but went overseas to teach. I'm now trying to get into the US school systems through subbing which is why I accepted this two week assignment. It's for a group of 3rd graders who are exceptionally difficult. From what I have heard they don't act like this with their normal teachers. A typical day thus far has included screaming across the classroom, fighting, yelling, arguing, talking back, getting up and out of their seats. They just don't seem to have any respect for their classmates or me. I have already asked the vice principal to come in and two other teachers have stopped in when they heard the children shouting. I'm at the point where I do not want to go back into the classroom whatsoever. Some of the things that I have tried so far are taking away recess, involving administration, and sending kids out of the hall. As well as giving whole class silent lunch. Nothing seems to be working though and I always leave extremely frustrated because we haven't accomplished much in the three days that I have been there. I'm thinking of trying to give silent lunch based on how long it takes them to quiet down. So, for every minute it takes them to settle, I'll keep a total minutes of that and have them do silent lunch for however long it takes. At this point though, I don't know what to do, so any suggestions would be amazing! They also have state testing at the end of the week and I'm unsure at this point if I will be the one administering it or not. I'm really afraid that I will be based off of the school but I've also never administered a test like that before. Needless to say I am overwhelmed, frustrated, and nervous! So, any suggestions for classroom management at this point would be greatly, greatly appreciated!!!
