For over 80 years, Cub Scouts have been having the time of their lives making new friends and learning new things in an environment designed to help them succeed. From building his own pinewood derby® car to learning how to roast the perfect marshmallow with his best friends at a family campout, your child will LOVE being a Cub Scout. So if he's in the first through fifth grades, or 7 to 10 years old, then it's time for him to have some fun … with the Cub Scouts.
