Help Feed the Hungry and Build Kids' Vocabulary at the Same Time

How would you like to be able to make a difference in ending world hunger, while improving your child's vocabulary at the same time? Free Rice is a cool web site that does just that. It's a simple vocabulary question and answer game (that's addictive, too). For every answer you get right, the site donates 20 grains of rice to the United Nations World Food Program. The vocabulary game is run by a computer program that automatically adjusts to your skill level.

The site is sponsored by Harvard University and the United Nations World Food Program, and all of the money earned from the site's sponsors goes directly to the World Food Program. Pretty cool, eh?
