Erase the rules that are unfair. Arrange for a person from the legal profession to take part in a mock trial. Make sure students are fully prepared and know their parts. Present the mock trial in the classroom or to the entire school. After presentation, allow time for class to ask the legal professionals questions about their jobs.
Retired persons are usually eager to help out.
If you can not find a scripted mock trial, you and the class can work on one of your own. Ask an off-duty policeman to come to class to testify. Discuss what they think the Constitution will mean to their children. Dictionary, pencil, paper. Restate the title of this lesson.
