FreeRice is an educational website started in October, 2007, to raise money to end world hunger. Multiple-choice questions are chosen from several subjects, including English, mathematics, geography, chemistry, and others. Each question that is correctly answered earns the site enough money to buy a donation of 10 grains of rice. The rice is paid for by sponsors of the site when questions are answered correctly and the rice is distributed by the UN World Food Program.
The site was begun in October, 2007, by computer programmer John Breen. It started with only the English Vocabulary game. After a while, many other games were added. The rice amount for each question answered right started at 10 then for a long time was moved to 20 and then was recently moved back to 10.
One selects a category (the original English Vocabulary game is default) and if the question is answered right, various sponsors of the FreeRice website will donate 10 grains of rice to the hungry. If answered incorrectly, no rice will be donated and an easier question will appear next.
