FreeRice is a way of building your vocabulary while doing a good deed. The website is sponsored by the World Food Programme which aims to help end world hunger. On FreeRice, you are presented with vocabulary questions. For every vocabulary question you get right, the World Food Programme will donate 10 grains of rice to help fight world hunger. Pretty cool, right? FreeRice also has options for answering questions about geography, foreign languages, paintings, and more.
