Any boy who is 10 or 11 years old, or in fourth or fifth grade, can join as a Webelos. But first, you must earn your Bobcat rank if you haven't already. A Webelos patrol is made up of up to 10 boys. Boys alternate being patrol leader. Webelos meet weekly to complete 20 Activities to earn rank badges, compass points, and the Arrow of Light. The Webelos patrol also attends and participates in the monthly pack meeting. In keeping with Cub Scouting's family-oriented principle, parents are encouraged to attend den meetings and pack meetings. Rank advancements are not given at the pack meeting without a parent or guardian present. Parents are also expected to help with at least one activity in a patrol meeting, and will need to be involved during outdoor activities such as camping.
