Every Cub Scout is a part of a pack. The pack is divided into smaller groups called dens. Each den has about six to eight boys. The Cub Scouts in each den are in the same grade and work the complete the achievements for the same rank.
Lion
The Lion den is for boys who are in Kindergarten.
Each Lion joins the den with his Adult Partner, who accompanies the Lion at all den and pack events. The Lion program encourages boys to learn and explore through hands-on, high-energy activities. The Lion badge is earned by completing five adventures, which are accomplished during the den meetings and outings. When an adventure is completed, the youth receives a sticker to put in his Lion Adventure Book.
Tiger
The Tiger den is for boys who are in first grade.
Each Tiger joins the pack together with his Adult Partner who accompanies the Tiger at all den and pack events. As the Tiger Cub finishes each of the six required adventures and one elective adventure he is awarded the adventure loop for that adventure, which he can wear on his belt. When a Cub Scout has earned all the required adventure loops, the Tiger badge is awarded at the annual Blue & Gold Banquet or a pack meeting.
Wolf
The Wolf den is for boys who are in second grade.
To earn the Wolf badge, a Cub Scout must complete six required adventures and one elective adventure. His parent or guardian approves each achievement by signing his handbook, and the boy receives an adventure loop for each completed adventure.

Bear
The Bear den is for boys who are in third grade.
To earn the Bear badge, a Cub Scout must complete six required adventures and one elective adventure that are more challenging than those for the Wolf badge.

After completing seven adventures, a Scout is awarded the Webelos badge at the annual Blue & Gold Banquet or a pack meeting.
Arrow of Light
The Arrow of Light den is for boys who are in the fifth grade.
Arrow of Light is the highest rank in Cub Scouting, and earning it prepares a Webelos Scout to become a Boy Scout. Scouts must complete four required adventures and three elective adventures to earn the Arrow of Light rank.
