We spend a lot of time looking for lesson plans and games that are actually useful and don't require a strong connection to the internet. Printables are okay, but Powerpoint games are probably the best. Especially when they're animated and you can keep score in your class.

I've put a bunch of ESL lessons and games up on the internet for you all. My life's work. Here it is if you want it. It's free! www.dangerouslyeasyesl.com, or google "dangerously easy esl"
