Having used Hit the Target (Click here to view, and download, the original) with nearly every class I have had over the last year, I decided to create a Christmassy version. The difference being that the students see a snowy blackboard and they have to hit a Christmas pudding!
It's great as a quick, very simple reward game. All you need is a working sticky ball and a good eye to spot the score each student gets! Of course, once they answer the question correctly. I would definitely recommend setting a standing point for them to throw from!
