Summer {Reading} Program

So our children continue the habit of reading we have taken advantage of our libraries' Summer Reading Program.
There are 3 levels. Each level they read for 10 days & 20 minutes. When they complete it, they take their slip of paper and redeem it for some prizes. Each level the prizes get better(and more of them). Our kids are so motivated; makes me think I should do something like this during the school year.
