Den 8

The Bear rank is for boys who have finished second grade (or are 9 years old). There are 24 Bear achievements in four groups. A boy must complete 12 of the achievements to be a Bear Cub Scout. These requirements are harder and more challenging than those for the Wolf badge. When a boy has earned his Bear badge, he may work on electives to earn Arrow Points to wear under his Bear badge.
 
 
 (Note that these achievements, as were the Wolf activities, are primarily done at home and signed off by an adult family member after the boy has completed each one. The book is then shown to the Den Leader who records the progress and also signs the boy's book.)

If the Cub Scout has not previously earned the Bobcat Badge, it must be earned first.
