I love to work with charities that my kids can get involved with. A friend of mine turned me on to Kiva a couple of years ago by giving me a gift card for my birthday. Basically you get to peruse the website, find someone you connect with, and give them a micro-loans to help their business start or grow. What could be better than empowering people in third world countries to make a living based off a skill set or trade that they prefer to work with?
It's a great teaching tool with children. You are able to talk about money, how loans work, and of course that not everyone is as fortunate as we are. There are pictures and stories about the people, and Kiva gives you updates as to how the person you are helping is doing. Eventually the person you loan money too should pay back their debt, and you are encouraged to help someone else out. It's amazing how far $25 in birthday money can go!
So next time you have some cash laying around (ha!) consider making a loan to someone. You might just change their life, and make a difference in yours in the process.
