OK, I sincerely doubt that there’s ANYONE out there who hasn’t heard of the “Free Rice” website, but have you checked it out lately?
It’s absolutely incredible. Not only can you test (and hone) your vocabulary, grammar, art, chemistry, MATH, geography, world language skills, etc., sponsors actually donate 10 grains of rice to the UN World Hunger Program for each answer you get correct! I had heard about it a long time ago re: vocabulary, but when I saw that algebra and multiplication skills were also practiced here, I was hooked! (As a Math Specialist, I’m going to encourage my students to check this out, too.) Check it out; it’s only a click away!
P.S. I’ve added a widget to FREE RICE on my sidebar, so you can access it anytime by clicking there. Feel free to copy it and add it to your site as well!!! It’s for a great cause!
