I stumbled across a site recently and wanted to share with all of you.
FreeRice
It's a philanthropic site designed to enhance your vocabulary. It lists a word and 4 possible meanings for you to guess. Each time you guess correctly, 10 grains of rice are added to your pot. Whatever your total - it is donated to communities in need.
I've been trying to spend a few minutes a day. Helps polish my vocabulary and helps hungry people, so a win-win in my book.
I'm not sure it would work for younger kids (maybe), but definitely middle-school or high school, as well as adults. The word generator gives progressively harder words.
The site is funded by ads, but it's pretty tastefully done.
I'd love to hear your comments.
