December Blog-Emphasize Shared Reading

I very much enjoyed reading about shared reading.  I realized that I do this quite a bit, with my younger students, in music class!  I have done this in my Kidwatching group, but I need to incorporate this more.  I was glad to see that there was a read aloud "What to do..." portion included.  It helped me to understand ways to engage the reader and to promote gaining meaning from the text.  Having these examples of questions and directions has opened my mind to new ways to help them learn from the text.  ("Turn to the person next to you, and discuss how Kenyon can solve his problem," "Talk in pairs.  How has Little Dolly changed?  What happened to Kenyon?  How have they changed as people?,"  "Let's read this page together.  As we read, think about what's the most important thing about what Trudy did.  Reread the page with your partner if you need to.")  I also liked how it used The Witch of Blackbird Pond as an example of introducing a literary genre.  Before reading the text, the teacher takes a snippet from a page and uses it to teach foreshadowing.  I like this idea!  It has helped me think about how to incorporate that strategy into my Kidwatching group.  I appreciate where they give more teaching tips for shared reading.  However, here is my question for those of you with more experience in these areas than myself:  If you don't have a transparency projector and your students are using a class set of books, how do you keep students from reading ahead and being lost when you ask a question or give a discussion thought?
