Learn and help

I heard about this site when I was in English classes. My teacher, Mr. David White, told us to look up for www.freerice.com. We al though it was some kind of game or reading practice, instead it was a cool site in order to learn and help.

This site gives you the opportunity to improve your vocabulary by answering synonym based question. You are scored and each time you fail it decreases. When you get a high average, it is shown in the screen.

However, how can you help? You could not believe it. With a correct answer you are donating 20 grains of rices to poor people. Obviously you are not asked to give the rice, an organization is the mediator through government in order to have the rice.
