Books are magic - in the sense that they ignite a love of the printed word, stories, and imagination like nothing else. But sometimes, to a small child, books seem like magic. As in, there's actual magic happening inside the book.
Case in point: Hervé Tullet's Press Here  (Presiona aqu í en español). In this interactive story, the reader is invited to press, shake, and tap various colored dots that appear on the page and, after turning the page, find that the dots have changed. When I read this to a group of preschoolers, they could not figure out how the changes were happening. In their minds, when I pressed on the one yellow dot and two appeared on the next page, I was performing magic.
Press Here is such a wonderful book that it was chosen by Colorado Libraries for Early Literacy  as one of their CLEL Silver Bells  - books that especially exemplify early literacy skills learning. Playing is one important way in which children develop the skills they need to become readers, and Press Here is certainly a book that invites play. CLEL has also provided an activity sheet  with ideas for how to extend play after reading the book - and build even stronger pre-reading skills!
