I created a card game to practice oral arithmetic with my young ESL students, mostly between the ages of 8 and 16. They've been enjoying it very much so I thought it might be worth sharing. It easy to make your own deck and a game is usually finished in about 10 minutes.<p>If there's any feedback, I'd be happy to hear it. I've never been able to play test with adults or native speakers, so that would be really interesting to hear about.
