Divide your class in two groups. They each need their own small white boards or paper and a pen.
Two students come to the front of the class (one from each team)
Show the first question on the board. They each write down their answer. The team mates then write down what they think their friend at the front of the class wrote down.
Check the 2 students answers, and see how many people in their team guessed their friend's point correctly.
The same number of answers = the number of points.
very fun and easy warm up / time filler.
