Donate Rice by Playing
FreeRice is a new online quiz web site where you can play English vocab quizzes and at the same time, contribute to the donation of rice to the impoverished regions of the world. When you visit the web site, you can play a vocabulary quiz where you have to choose, out of four choices, one answer that has similar meaning as the one given. If you get it right, you will be donating 20 grains of rice. If you keep playing, you will start seeing more and more rice being donated.

The money for the donation comes from the advertisement at the bottom of the screen. I don't know how the ads can actually support the price of the rice; when one is playing the game, what's the chance that one will pay attention to the ads and click on them. Perhaps the ads are based on the number of times they are shown but not the number of times they are clicked.
Anyway, the game is addictive and you can improve your vocabulary skills while doing a good cause for the less fortunate people of the world.
