Free Rice is an organization that donates grains of rice to the poor. I first went on this website -- freerice.com -- because my enrichment teacher recommended it. I tried it and I liked it. If you go to the website and answer questions, they donate grains of rice. You can change the subject of the questions to your liking. The website automatically starts you on level one with English vocabulary, and there are 60 levels. The subjects are humanities (famous paintings, literature, world hunger and famous quotations), math (multiplication tables and basic math), languages (German, Spanish, French, Italian, and Latin), English (vocabulary and grammar), chemistry and geography (world landmarks, identifying countries on a map, world capitals and flags of the world).
So, you can study for your next test and help feed the poor at the same time! It is great to feel that you are helping somebody.
