The FreeRice site (FreeRice is a sister site of the world poverty site, Poverty.com.) , has two objectives:
1.Provide English vocabulary to everyone for free.
2. Help end world hunger by providing rice to hungry people for free
The game is sort of like Word Power in Reader’s Digest. Lots of fun!
What so cool about it? Play and for every word you get right- they donate 50 grains of rice to United Nations ( made possible by advertisers on the site). I all ready donated 500+ grains.. this hour :-)
The site is fairly new- but growing by leaps and bounds!
warnng- highly addictive!
