I've seen this idea several different places, called Bazinga! or Zap! You fill in questions, have students break into teams to answer each question. When they answer a question correctly they earn a point and a Bazinga! Card. The card may add or take away from their score, giving it a little extra excitement!
This download is a zip file with the PowerPoint including pages for questions, bazingas and a scoreboard, a PDF of Bazinga! cards, and a student handout to show work on.
I typically use this for test and quiz review.
Make sure to enable content so that the scoreboard will work!
