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.
This could be used with younger children to introduce the idea of persuasion. Give children a partner, one to be on the side of Jack and the other the Giant. Ask them to discuss who is right, giving evidence that was heard in Judge Jenny's court. Then write a persuasive letter to Judge Jenny from the perspective of Jack or the Giant explaning why they are right.
