Check out freerice.com if you want a fun way to get smart and feed the hungry. Basically they ask you questions from the subject of your choice and every right answer = 10 donated grains of rice. You do not have to sign up to do this and the subjects are math, chem, foreign language, vocab, geography, and art history. The questions start easy and then scale up.
It's a very addicting game that offers an easy way to donate. Just give it a shot and the games help your mind more than you might think! We could also start a newschoolers group on the website too if anyone is interested.
