3rd & 4th Grade Book Discussion

We started our 3rd & 4th grade book discussion last summer and had some great experiences and the kids who attended all read the books!  This is particularly amazing because I can’t always get our middle school students to read the book (which can make a book discussion difficult), but our 3rd & 4th graders are reading stars.  We continued our book discussions into the school year and offered 3 more this summer.  The kids in these book discussions are great at answering questions about the book, the characters, etc. but often don’t discuss the book amongst the group.  Each child tends to answer the question individually and then we move on to the next question.  My goal for the fall is to really get the kids to talk and respond to each other and answer questions too.
Our next book discussion isn’t going to be until November; we are offering a number of other programs in September and October for the kids to participate in.  But now I’ve got to figure out what book we’re going to discuss, I was thinking about The Sasquatch Escape by Suzanne Selfors, Escape from Mr. Lemoncello’s Library by Chris Grabenstein, or Flora & Ulysses by Kate DiCamillo.  I also like using series books because the kids love series at this age.  We’ve done Geronimo Stilton, Frankie Pickle, and Moxy Maxwell.  I’m thinking about going with Flora & Ulysses, but if anyone else has some great suggestions for 3rd and 4th graders as book discussion, please let me know!  I’d love some other book titles to use in the future or if you have any great book discussion questions for this age group, I’d love to see those as well!
