At their first meeting, award new recruits a coloured plastic wallets to match their six colour with click fastening. In the pack includes key information for parents and for the cub
Guide to Cubs for Parents
Bringing the wallet each week earns a point towards whatever competition you want to run in your pack (eg best cub, best six etc).
Use the powerpack each week to tick off the badge components that have been completed (tell the cubs at the end of the meeting and email parents)
Use the wallet to keep evidence - consider issuing an exercise book / scrapbook for these to be added to by the cub.
Draw attention to the Promise and Law in the pack & note that when the cub has learned these, he/she may be invested.
