Students choose an option and uncover either SPIN or DON'T SPIN the wheel.
They can then stop the wheel and get points for their team - two teams works well.
To make it more fun I taped a mouse to an old textbook so that it couldn't move (use painter's tape or similar removable tape).
Then placed this on a spare desk in front of the TV.
Put an 'X' on the left mouse button and demonstrate how to tap it lightly to stop the wheel.
After students make their choice you can start the wheel spinning (if they get SPIN) and they can come to the front desk and stop it.
There are 30 shapes to uncover so enough for a small class to all have a chance.
