A favorite with my younger students back when I taught ESL in Asia was the “Hammer Game.” It involved dividing the whiteboard into categories (for example, Fruit on the left, Vegetables on the right).

Then the students were divided into two lines. The first two kids came up and were given squeaky rubber mallets. I would hold up a word (sometimes with an accompanying picture, depending on the difficulty level), and the first kid to run up and hammer the correct section of the whiteboard won the round.

Very fun for the group and you get a bonus case of tinnitus at the end of the class period!
