On the Free Rice website, you answer English vocabulary questions, and for each correct answer, ten grains of rice will be donated to help end hunger. The difficulty of the questions will be adjusted depending on if you give correct answers or not, so this charity game is equally suitable for children and for grown-ups.

Subjects include: English vocab, chemistry, geography, foreign languages, math and art.

FreeRice is a non-profit website run by the United Nations World Food Program.
