I hope these help you. Adding game:. Get the class into 2 teams.Ask capitains a question in any language. When their team gets it correct they come up to the board and hit one of the squares which shows a number. eg: TEAM A 100 points. Do the same again for TEAM B eg 45 points. Go back to team A and they get eg -45 points. They have to then take 45 from 100 so TEAM A now have 55 points. Neither team can tell who is going to win as the numbers range from -150 to 200.
