My Year 4 class are always noisy. They come into the classroom and continue to talk during the morning work set. Even after I have reminded them, they continue to talk! During the register I have stated I expect silence- this is met by the majority but on few occasions has this actually happened for the whole class. During lesson time, my class talk loudly. I have said quiet partner voices are to be used if they need to and have used 'silent working' as a consequence. I have tried the 'hand in the air', shakers and golden time rewards but these do not seem to have the effect I am looking for. What can I do to get my class to be quiet when I have stated it and during independent activity time? I'm really stuck!
