Attention all compassionate nerds: Increase your already robust and burgeoning vocabulary while helping to feed the hungry. Advertisers pay for the site, and as you play, you earn grains of rice to be donated. Since FreeRice went live on October 7, web users have donated over two-and-a-half billion grains of rice – enough to feed more than 125,000 people.
FreeRice.com is the sister site of Poverty.com. If you have questions/cocnerns about where the rice goes and who distributes it, etc., I encourage you to go check it out for yourself.
The fun part (from the site): FreeRice automatically adjusts to your level of vocabulary. It starts by giving you words at different levels of difficulty and then, based on how you do, assigns you an approximate starting level. You then determine a more exact level for yourself as you play. When you get a word wrong, you go to an easier level. When you get three words in a row right, you go to a harder level. This one-to-three ratio is best for keeping you at the “outer fringe” of your vocabulary, where learning can take place.
There are 50 levels in all, but it is rare for people to get above level 48.
Oh man. It's addicting! I'm not sure how long this site will last, so don't wait to play!
