I am teaching a mixed age class of thirty six Y4/5s one day a week. I have had them for 7 full days so far. It has in it about 7 or 8 boys who have the potential to be really disruptive.The last lesson of the day (and week) is PE. THe hall has a terrible accoustic. The usual culprits have had enough of listening, and mess about. The rest of the class get very little PE, and a lot of time sitting about while i sort things out. This week I took paper and a pile of text books with me to the hall. Anyone sliding across the floor, or deliberately mishearing my instructions, was given a book, sent to a corner and told to copy it out. I tried to do this with as little fuss as possible and keep going with the lesson. I managed to stop the dangerous sliding this week. Is this approach apropriate? I know that they all need to do PE. But i can't think of another way to stop them finding entertainment in the bad behavior. But as i only see them once a week, it is a real battle to keep on top of things. And yes i do the positive thing, with points for good behaviour. One table in particular has 3 boys that cheer when they come last on the points table... I don't know what to do about this either. Am feeling very fed up. Have no behaviour issues with the 2 other classes i teach... I just feel i am losing it with this class, and turning into a weak inneffectual teacher.... and they can sense it. Any thoughts?
