Put students in groups of 3 or 4 (just for the day) Have them write on a piece of paper everything they can remember about the book (if you have enough copies let them see the book).
Explain how to do the questions, ie they can answer as a group, but they have to answer in one min
First question goes to any team, the next questions go to each team in order (so each team has a chance to answer). If a team doesn't answer correctly anyone can buzz in (ring in, etc). I don't have buzz in toys for everyone so be creative.
