What Is Cub Scouting?
Cub Scouting is fun! No matter what grade you are in, first through fifth, it can be a blast. Do you like to learn by doing? This is just the place. You can learn to tie knots, set up a tent, shoot a bow and arrow (archery). Have you ever cooked a meal on a campfire? Sent a secret code to a buddy? Built a birdhouse? Played Ultimate? Hiked? Earn rewards for doing these things in Cub Scouts.
Cub Scouts Belong to Packs and Dens
As a Cub Scout, you will be part of your own pack.
The pack is divided into smaller groups called dens. Each den has about six to eight boys. All of the Cub Scouts in your den are in the same grade and may even go to the same school.
The Cub Scout pack belongs to a church, a school, or some other group of people in your community or neighborhood. This group makes sure your pack has good adult leaders, a place to meet, and exciting things to do. The group gets help from the Boy Scouts of America, which is part of Scouting around the world.
Cub Scouts Do Things and Go Places
Have you been to the local police station and talked to the policemen on duty? Or visited the fire station and sat in the driver's seat of the pumper truck? Or visited the local TV station and sat in the news anchor's chair? These are some of the places you might go with your den or pack.
You might also build a pinewood derby car and race it on the track, build a sailboat or trimaran and race it in the raingutter regatta, or build a spaceship and race it to the stars in the pack space derby.
Cub Scouts Earn Awards
Each time you complete an accomplishment or learn a new skill, you will be rewarded. Sometimes the reward is a bead or a patch. Sometimes it is a smile on your parents' faces to see you grow and learn.
