Mr. White and Katie Senzig told me about a web site that’s fun, educational, and humanitarian. It’s a vocabulary game with 50 levels. When you answer questions correctly, you move to a higher level. Each one you miss moves you to a lower level. More importantly, the sponsors of the web site donate 20 grains of rice, through the UN, for every word you answer correctly. Hence the name, “free rice.”
Here’s the link.
