I'm in a very similar I'm in a very similar position, though I am half way through 2 days with a Y3 class. They just didn't listen today, and to be honest I took away around 6 minutes of their golden time today. Having read your post I do agree that it may show how 'bad' I am, but the problem is if I hadn't have done it, the kids would have got away with it and would have walked all over me tomorrow. I basically followed through with discipline. Thankfully the TA said they were the same in Y2, which is comforting, but you never know whether they lie through their teeth. It's tricky. My plan is to give most of the golden time back tomorrow, but to those children who really are listening (there are a few poor souls who sit there waiting). You have to experiment to see what works. I admit I'm inexperienced and it's hard with a class at the start of the year you don't know, but you have to insist on good behaviour, and if that means taking all their golden time away, then damn well do it! (you don't have to go back to that school anyway).
