I use Google+ communities with my literature classes. You can read more about my creative classroom practices on my blog: www.room257.wix.com/room257.
I post in-depth questions and break them up by chapter.
These questions are meant to spur deep thinking and analysis. They are not easy, comprehension questions.
This product contains questions for chapters 25-32 which comprise Book III of the novel.
I post these questions in Google+ and ask students or discussion groups to respond to them.
They would make great group discussion questions.
You can also use them as prompts for essay tests/quizzes, or you can use them to guide a class discussion led by you.
