After reading extensively about Literature Circles and seeing all of the products out there, I created a program that worked best for 6th, 7th, and 8th grade readers. I found it well received by middle school students reading below grade level.
The packet includes instructions and worksheets for 7 different "jobs" (Connector, Discussion Director, Investigator, Literary Luminary, Word Finder, Artist, Author Analyzer). The assignments lent themselves well to a shared Historical Fiction or Science Fiction novel study.
Each "job" worksheet provides specific instruction on the independent work required as well as guidance for how to be involved in the small group discussions.
I have seen great results using this technique paired with a great book to engage struggling readers.
