I love, love, love this activity! Did I say love?
After your class is done reading, you split the kids into groups to create "FAT question" (explained in the activity). They then go back to whole class. You choose some kids to "play" the characters from the book and answer the questions as if they were them. I cycle the kids out after one set of questions so that other kids can "play" they character roles. I love that this forces everyone to be involved in the discussion.
I have included a directions sheet for both the teacher and the students! So FUN!
