The Giant puts his point of view with evidence to Judge Jenny to try to persuade her that Jack is in the wrong. Jack defends his actions and Judge Jenny sums up so that the audience can discuss and decide.
In the classroom this would be useful for starting a discussion about right and wrong. Children could make their own puppets and role-play each characters' side of the argument. They could then write in speech bubbles something their character might say to persuade Judge Jenny they are right.
