This site comes to me from my colleague, Jen Erickson. Free Rice is a site where students can answer trivia questions in the areas of English vocabulary, foreign languages, humanities, geography, math and chemistry.
Here's the neat part; for every correct answer 10 grains of rice are donated to the United Nations World Food Program. If the student answers incorrectly, the question will be repeated for another chance. Each time a question is answered correctly, you are shown how much rice you have donated. The more answers you get correct, the more difficult the questions get. If you get answers incorrect, the game gets easier.
Check out Free Rice and share it with your students.
I would like to thank Jen for sharing this neat site!
