Earning the Arrow of Light has four core adventures. They repeat the core requirements of the Webelos badge, so doing ALL the Webelos and ALL the AOL core each year wouldn’t give a well rounded program for your boys, however, I wouldn’t want to discourage boys from still earning the Arrow of Light because many boys are motivated to do so.
So, during a one year cycle, a Webelos den leader could teach
5 Webelos core adventures
1 AOL core and perhaps a geocaching activity. (Building a Better World, partial Camper).
This is enough to support and encourage boys to do the rest, but it leaves time open for the other boys to get a good variety of belt loops rather than repeating the core topics twice in one year.
This would leave the aspiring Arrow of Light scouter to do Duty to God in Action 2 and Scouting adventure during personal time. The den leaders might work with ward leaders to help the boys plan when to visit a scout troop and to finish camper on a ward or family campout or outdoor activity. (This is in addition to the walkabout used for the Webelos core requirements)
How to help it happen:
Scout will have to attend all den meetings!
Work with 11-year old scout leader to plan in advance when the boys can go to a scout meeting. Have a special day (like a Saturday) to do the entire scouting adventure core for any boys who have completed the rest of the Arrow of Light requirements.
Work with ward to earn camper at June Priesthood campout, ward campout, or if the ward doesn’t have a family type camp, do partial camper including geocaching and planning a program and send the rest home as homework including the campout.
During the six months where Faith in God 1 is NOT taught send home Faith in God 2 as homework. Send home one elective as homework if needed.
