Only the ability to guide a student or team through creative problem solving steps. The list of activities is only limited by the teacher and students imagination. Some students prefer to begin with a more concrete activity such as presenting a short playlet about the book. I have found that the usual comprehension, basal reading has left an extremely negative feeling concerning reading and has ruled out reading as an elective, enjoyable activity. I, therefore, use many different activities to stimulate fun and excitement for reading.
Students also enjoy rewriting fables and folktales into modern day language.
Some students enjoy demonstrating a new skill or interest they have because of the book they have read. As each team or student presents their projects, new ideas are generated for other groups to develop. Having enough time for all to demonstrate seems to be the biggest problem.
