Each students starts off with ten coins. For each question, the teacher decides what the reward/consequence is for getting the question right/wrong. This keeps the game moving and exciting.
Show one of the problems to your students. It works best if they have their own mini-whiteboards. After a certain time limit, they should show the answer to the teacher.
Here are some different round ideas:
-If you get it wrong, pass two coins to the person in front of you.
-If you get it wrong, pass three coins to the person in behind of you.
-If you get it wrong, give half of your stack to your neighbor.
-If you get it wrong, give one coin to your neighbor.
-If you get it right, donate one to someone in the room. If you get it wrong, donate two.
-If you get it right, request two coins from someone else in the room.
Another addition is adding a pot between two neighbors. For example, if both neighbors get it wrong, they put 1 or 2 coins in the pot. The next person to get it right earns the pot as well.
Includes answers at the bottom right hand corner of the question.
