This is a great book, which I used as I had one child in particular that constantly would shout out, but not on purpose. The book teaches easy strategies that don't seem to preach or single anyone out. Also gives an excuse to have a bit of a science lesson and stink the class out with vinegar and bicarb! (or mints and coke if you don't want to breathe in vinegar all day long) I have now bought about half of Julia Cook's books. Beware that as an American counsellor/writer the book does contain some Americanisms, so best shared with a class, rather than children reading the text directly.
