A Literature circle is a group of students reading the same book. They meet every once in awhile to talk about what they've read, and decide how much to read before the next meeting. Discussion Director asks questions about the reading, and directs the discussion. Vocabulary Enricher chooses difficult or differently used words from the reading, and finds the meaning of those words. Literary Luminary picks passages from the reading that have a special feeling or standout from other passages.
Connector connects a part of the reading to something outside the story.
Process Checker keeps track of who is doing what. That's a quick explanation for the literature circles.
