ART - Famous PaintingsThis is not higher order thinking, but as I said before:
CHEMISTRY - Chemical Symbols (Basic), Chemical Symbols (Full List)
ENGLISH - English Grammar, English Vocabulary
GEOGRAPHY - Identify Countries on the Map, World Capitals
LANGUAGE LEARNING - French, German, Italian, Spanish
MATH - Basic Math (Pre-Algebra), Multiplication Table
I think this is another interesting use of the web, combining educational activities (not just the fairly simple vocab building activity, but educating folks about hunger itself - including links to the sister site poverty.com) with contributing to the greater good. I could see this being a springboard for writing activities, social studies units on developing countries or poverty, and even some math and science activities (calculating how many grains of rice it takes to feed a certain number of people, nutritional value of the rice, caloric intake, etc.)So, point your students (and your friends) to Free Rice and perhaps they can have a little fun, learn a little, and help provide rice to those in need.
Lots of possibilities here for creative teachers and students and maybe, just maybe, doing some good in the process. And it's also, you know, kinda fun.
