So far on my (very limited) experience on supply, I've noticed that the classes I've had are very chatty and rather loud. I'm aware that children like to test out the boundaries for supply teachers! But I'm usually one of those people who doesn't mind the noise in a classroom as it's usually work-related, however some children find it hard to concentrate. So how do I keep the noise level at a reasonable level for all? I have tried music, rewarding children and other strategies but is there a fool-proof method that I'm just missing that doesn't resort to a total-silence rule? Btw, how do you format posts so that all the writing doesn't show up all clumped together?!
