I currently teach at a technical school where most students are fresh out of high school. There are 6 hour lectures on some days which challenges their attention span. For review they take a multiple choice practice test and keep the answer sheet. They then break up into two teams. I draw a baseball diamond on the whiteboard with targets scattered throughout. They then take turns coming up to the plate and throw a suction ball at the white board. I then ask the player what is the answer for question number 15 for example. (or any random number) Only that person answers. If the answer was correct the team gets the score. We then review the question and answer regardless. After the first inning they all have an opportunity as team to look over the practice test and answer sheets. The game continues until all the questions are answered. This keeps the students engaged and working together.
