Many teachers play The Quiet Game when they are in the hall and have to wait for some reason. As a sub, it happens to me fairly frequently because I am not familiar with the class schedule or how the clocks in the school run (in some schools every clock says a different time, and as a teacher you get used to knowing which ones to follow). Anyway, I got bored with the regular Quiet Game where everyone sits quietly and you choose a girl and a boy to start it off. They walk up and down the line and tap someone who is quiet. Then they switch places and the new student gets to choose... and so on. One day I had gotten to counselor with a third grade class a full 10 minutes early because I misread the schedule and did not want to waste that time. So we played The Multiplication Fact Quiet Game. It is played exactly like the regular Quiet Game, only instead of the student just tapping another, they give a quiet student a multiplication fact. If that students gets it right, then they switch. You could apply this using any operation depending on the level of the students. Voila! Quiet students in the hall who are practicing math facts! Win-win!
