Cub Scouts are learning all the time and that learning can be reinforced by demonstrating to others what they have learned. Besides, Show and Tell can be really fun. Encourage your dens to plan a short demonstration, reading, or re-enactment of what they have learned or visited lately. Added bonuses are the improvements in presentation skills, and younger Scouts getting to see what the older Scouts are getting to do, generating excitement for future years in Scouting.
There aren't many resources and examples on-line for this topic, which is just a well. All Scouting is local. Set aside a little time during the pack meeting for some den
bragging demonstrations and find out what works best to your pack.
