I love http://www.freerice.org. Kids (and adults) are quizzed on vocabulary, science, art and geography and every time you get a question correct 10 grains of rice are donated to people in 3rd world countries. The questions get harder and you move up levels as you get more correct. Meryl
Wow.. I never realized there was more there than vocab! I am loving the country one!! Thanks for opening my eyes!
