Today I thought I’d mention one of my favorite sites, freerice.com.

freerice.com blends together charity and learning in an interesting way – the site asks you questions and for every right answer you get, they donate five grains of rice through the World Food Programme.

The default setting is English vocabulary, the sort of multiple-choice questions most people remember from school where you have to pick the word that is the closest match to the given word. You can switch the subject to math, chemistry, even foreign language vocabulary lessons. It’s a pretty painless way to pass the time and do a little bit of good while flexing your brain a bit.
