Jacob isn't quite ten years old but he has a BIG problem. His dad's birthday is only a few days away and Jacob has only $1.38 to contribute toward dad's birthday party. To make matters worse, his dad won't let him mow yards until after he turns ten, so he can't make any money! It's a tight spot. How is he going to solve it? Skateboard down Jacob's street and knock on some doors with him as he uses his head to work out the problem. He learns a few things and even manages to teach his dad something as well.
