Alien Hunt - An ActivInspire Flipchart
The object of this game is for students to erase squares and try to find an alien hidden underneath. You can use this with any subject and any questions. I would often use this game when going over homework. Have teams submit their answers in groups of 3 questions at a time. If they get all 3 correct they uncover 3 squares, 2 correct they uncover 2 squares etc. The winning team is the team with the most aliens found. Once the game is played you can move the aliens and play over and over.
If you are a math teacher interested in the full version of this game with questions included I have that product listed as well.
