I use this activity as part of Daily 5, read to someone. After each person in the pair has read their book, they get together with a partner to complete the KWL book report. Each person answers the questions: What you know about your partner's book and what you want to know. The children then take turns telling their partner about their book. When they are finished, the last questions can be answered that tell what they learned and their favorite part illustrated. I really like to see children share and it's a nice variation on a traditional book report.
