How do teens display leadership in their family?

Answer 1

They don't. Teens are under tutelage and under the control of the head of family, who does the leading. The teens learn from their parents.

Answer:

To display leadership a person must identify problems or opportunities, formulate a plan to resolve the problem or exploit the opportunity and then gain the acceptance of others for that plan. This applies to teens and anyone else. In the case of a teen, as an example, he or she might want to have a family camping vacation. They would then find local opportunites and costs for such a vacation, identify family schedules for going and develop a "sales pitch" for the event.
