I was going to say the same thing that st pauli girl mentioned...public libraries usually have summer reading programs for kids. They can keep track of how much they read and earn prizes at the library, such as passes for fun places in the area. My son's been doing it since he was 3-years-old and he loves it. Personally, I don't have a problem with inspiring a child to attain a certain goal by rewarding them for their efforts. It's never been a long term necessity in my house. It's used long enough to instill a certain behavior, and then we phase it out.
