Learning financial Responsibility

My boys just have to have the new Iron Man Repulsor toy. I told them to go in their piggy banks and see how much money they have. This toy cost a crazy 17 dollars. They came up with $26 put together, so I told them that if they washed my car today I would give them each a dollar and they could each get a toy.
I'm so proud of them for sharing their money; first of all because one son gave the other one at least 6 dollars.  Without it, he could not have gotten a toy. Secondly I am proud of them for taking up the challenge to wash my car to earn extra cash on top of the other chores that they have to do on a Saturday. They are really growing up!
