Lion

The Lions den is designed to offer a low-key introduction to Cub Scouting, giving families a Scouting option at a time when many would otherwise commit to sports programs that start in kindergarten. Lions will be part of a Cub Scout pack like their older counterparts; however, their participation in pack activities will be limited.  It is optional to participate in fundraising projects, overnight outings, or other activities that are longer and duration and may be beyond their ability. Instead, they will attend two or three pack meetings, as well as age-appropriate special activities. They’ll also wear a Lion T-shirt instead of a Cub Scout uniform and will earn stickers instead of belt loops.

On the advancement trail, a Cub Scout progresses towards a badge of rank based on their grade. They need not have earned the previous rank in order to earn the next.  Each of the ranks in Cub Scouting has its own requirements that are age appropriate, so earning a rank below a Cub Scout’s current grade is not permitted. As a Cub Scout advances through the ranks, the requirements get more challenging, to match the new skills and abilities they have learned.
