Wolf Cub Scouts. Second-grade boys graduate into a Wolf den. They go     to weekly den meetings on their own, but their families still help them      work on the requirements for the Wolf badge.

Bear Cub Scouts. Boys in the third grade are members of a Bear den.        They also work with their families to do the requirements for the Bear    badge, but boys this old have enough knowledge and skill to take on          more of the work by themselves.

Webelos Scouts. Boys in the fourth and fifth grades become Webelos     Scouts. Webelos Scouts do more advanced activities to get ready to     graduate into Boy Scouting
