Here's an idea I find very useful in class. Rock Paper Scissors dice can be used to decide the winner of a game, who gets points, who asks and who answers a question, any forfeits for the students, to beat (or not as the case my sometimes be) the teacher or anything else you can decide.
Simply print out the template, cut the outside lines and score the inside lines (printing on a stiff white card works best), stick it together and you have a dice. You will need at least 2 to make them useful.
