This is a wonderful idea I came across yesterday as I was looking for a game to practise food vocabulary.
Balloon Tennis!
The idea is pretty simple: We stick two plastic spoons to the back of two plastic plates to create two funny-looking rackets. As a ball, we use a balloon. Students can play tennis with their rackets, but under a rule: every time a student hits the ball, he/she has to come up with a word from the group of words you want to revise to get a point. For example, if your lesson was about food vocabulary he/she has to say a food name. If the student hits the balloon without managing to find a word he/she gets no marks.
Maybe you will find ways to use this game beyond vocabulary revision. Have fun!
