Free Rice is a non-profit organization that helps teach children vocabulary, while also helping feed third world countries. This site can help teach students about how to help others while still being able to learn. For every vocabulary question a person answers correctly, the United Nations World Food Programme will donate 10 grains of rice. How you answer a question right is Free Rice gives you a word and you are supposed to define the word. It gives you four choices to choose from, and all you need to do is to choose the best answer like on a test.
