This one is easy and the kids really like it. Its very simple. You introduce the new English. Repeat it a few times for clarity. Then, draw two bombs on the board. Label one you and the other your class. Then, draw two looonnnng fuses from the bombs. Tell them that if they are good you will erase your fuse until you blow up. But, if they are so-so, you will erase their fuse and "Bon gah!" they explode. Repeat the English again and then start erasing.

They'll love this. Fret and hammishly look terrified as your fuse gets shorter and shorter. Hover your eraser over their fuse if they start to slack. Get mixed up and start to erase their fuse even if they did a good job.

This game is simple enough, one variable, so that they can still concentrate on the new English pattern and they'll easily soak it up because they will be having a really good time. Also, you can make sure any tricky pronunciation is followed early, because you control those fuses. This one is really good for teaching a new element. It's a great group game, but it doesn't lend itself to individual practice.

note again: remember with teaching here, whether its kindergarten ESL, preparing college age students for the TOEFL, or even teaching business people the dreaded ESP (English for specific purposes) sometimes a good game really makes time fly and learning easy. Don't fail to learn as many games as possible.
