I know there are a lot of good people out there, so I wanted to let you know about this website, in case you don’t know already:
You get to quiz/ learn about words, science and other info. For each answer you get right, a grain of rice is donated to the UN World Food Program.
Awesome idea–and a great way to teach kids new words and how to help people.
