Designed for teachers, this simulation of a criminal trial addresses the workings of the trial system by using the children's story, "The Three Little Pigs." The Big Bad Wolf is put on trial for destroying the pigs' houses. By having students assume roles and use the non-scripted character profiles, the simulation allows information to be presented that has the audience wondering if the wolf is guilty or innocent. A jury of students weighs the evidence and decides on a verdict. The simulation not only teaches about the judicial system but also explores the need for rules and develops communication, cooperation, and evaluative skills. The simulation contains instructions for the teacher, a duplication and distribution guide, description of roles to be played during the trial, discussion questions, trial vocabulary words, and pre-trial student materials.
