I always play a review game the day before a test.
I split the class into groups of four, each group gets a dry erase board and a marker.
I will show a question from the game on the screen. They get a little time to talk to their team and write down an answer.
I then ask for all groups to show their boards.
The groups that got the answer correct get the points for that question.
The group with the highest points at the end of the game wins.
