SUMMER READING CAMP

    Have you heard of the "summer slide"? Unfortunately, it's not the fun kind of slide you'll find at a water park or playground. This slide is different. It's a slide that no mom wants her child to ride.

    Many studies show that kids who don't read during summer vacation actually slip in reading ability by the time autumn term starts.
