Quiz and quieten

Sometimes a class is not necessarily off task but really loud. As a personal preference, I don't even mind if students are talking. It does not bother me at all but when those little voices turn into big voices it becomes a bit much. Naggy reminders and clapping patterns become like water off a ducks back after a while so I like to do something a bit different and keep it fun: quizzes! 

I just look up a list of trivia questions online about whatever theme they're learning about, eg space. And as the noise elevates, ask a question and tally the points on the board. This could even go towards their prize at the end of the day.
