Thanks to the Langwitches blog, I just learned that Free Rice, the great English vocabulary game that pioneered the now-popular idea of having advertisers make a contribution to a worthy case for every correct answer to a learning game, has gotten even better.
It now has questions related to grammar, geography, art, foreign language and math, too.
Besides the social contribution students make by the playing the game, I particularly like it because the questions change depending on the success of the player — if they’re doing well, the questions get harder; if they’re getting a lot wrong, the questions get easier.
Free Rice was listed in The Best Online Learning Games — 2007. You can also find it on my Best Websites page, which is designed for student self-access.
