My first mini-lesson for reading workshop was, "growing readers" choose books that interest them. Wonder #611 worked perfectly with this lesson. We discussed why and how we judge books by their cover and how the cover usually tells us what the book is going to be about, which tells us whether we may or may not be interested in the book. It was especially helpful for my students to hear from Wonderopolis that, "Of course, when you're looking for a new book, the first thing you're likely to see is the book's cover. A book's cover is like a an advertisement. It's supposed to intrigue you, give you an idea of what the book is about..." Furthermore, in the Try It Out section of the Wonder, Wonderopolis gave some helpful tips for students when looking for new books. The first tip encouraged students by saying, "Follow your interests!"
