I use this sheet for whole class books; after completing a reading assignment, each student comes prepared with at least 4 questions answered to initiate the conversation. I have one student as the book club "leader" who comes with 7, and I give them DOK sentence stems (readily available online) and ask them to lead the conversation.
My favorite part of class is no longer introducing new interesting ideas; it's walking around and listening to students and what occurs to them! I learn so much! If you'd like my "book club rules" sheet, message me and I'll share that! I use this with The Giver, Fahrenheit 451, and Roll of Thunder, Hear my Cry.
This sheet can also be used for students to discuss their independent reading book to introduce a book to a group.
