Free Rice: your learning donates food

Today I'd like to encourage you all to visit the site freerice.com
Freerice belongs to the World Food Programme, a branch of the United Nations that provides food to 90 million people every year. You can collaborate if you enter the site and play the educational games. For each right answer, you donate 10 grains of rice. Sponsored banners pay for the rice donated and the game improves your writing, speaking, thinking and, as a consequence, your marks. Click here and give it a go.
