I have a boy in my class who I am finding difficult to handle at the moment. It is nothing major he does, just low level disturbances and I feel that I am correcting him all the time. For example pulling faces during carpet time, not sitting properly, calling out, if you ask the children not to do something, he will immediately do it. He is very defiant. I have tried all of my usual strategies to deal with this but they have all failed. Would be grateful of some help on how to deal with this.
