We all have had a student or two who were a handful in the classroom .I tried this trick more than once and it worked like a charm . I pick out a surprise activity, such as an extra free time , a small treat , no homework or quiz that week, then write "SURPRISE" on the board. Throughout the period, if the class gets noisy or students shout answers or get out of their seats without permission, I erase a letter starting at the end of the word. Add missing letters when everyone is behaving well. If the complete word is intact at the end of the period, the students get the surprise.
