Cub Scouts wear a uniform that gives each Scout a level of identity within the den, the pack and the community. The Scouts learn teamwork by meeting and working together in a den of four to ten boys or girls under adult leadership. They learn and apply the ideals codified in the Scout Oath and the Scout Law through an advancement system using age-based ranks earned by completing required and elective adventures. Some advancement is done in the home and is intended to involve the entire family and many Cub Scout activities include family members.
