I firmly believe in older Scouts being role models for younger ones. Some of the adventures in the 2015 Cub Scout program have portions which are explicit in stating that an older scout should help a younger scout with something. What isn't really shared is how many of those will also count toward parts of adventures for the younger scouts, as well.
Yes, I know... the main image for this post shows a Boy Scout, not an older Cub Scout. That's okay. It's actually this photo that made me think of cross-referencing requirements between ranks. This particular Boy Scout is my godson. He fulfilled part of his rank requirements earlier this year by teaching my Wolf Den some knots, which were electives for them.
I know this isn't a new concept, but with planning, many opportunities exist for Cubs as young as Wolves to be helpful to younger scouts. Even the ones that don't lend themselves to easily be a "mentoring moment" are still good to keep in mind for pack activities.
I have listed many of these teaching opportunities and shared requirements below:
