FreeRice.com donates 20 grains of rice to the U.N. World Food Program every time a player selects the right definition for a particular word. This vocabulary quiz site, which debuted in October, has generated interest from children and adults alike, to the tune of more than 8.2 billion grains of rice to date. The rice is paid for by advertiser income.
The site was created by a computer programmer seeking to help his son prepare for the SAT’s verbal section. Teachers of all grade levels have encouraged their students to take a stab at this “game,” which includes words ranging from “solve” and “quickly” to “ebullient” and “spelunker.”
