All right, I found the FreeRice
website again in my favorites and decided to go check it out. It's not just vocabulary now and the donation amount is 20 grains of rice per correct answer. There's:
Chemical Symbols (Basic)
Chemical Symbols (Full List)
Identify Countries on the Map
Basic Math (Pre-Algebra)
Tip: You can rack up lots of grains with the Multiplication Table and make yourself faster at math at the same time.
