Beavers make a promise to do something good/helpful
Promise sheets, envelopes, pencils
In Lodges or small groups Beavers write on the clips of paper a promise to do something good or helpful ie help set the table, tidy room, be nice to little brother etc. The slips are put in envelopes and their names written on them.
the following week envelopes are opened and read and Beavers can say if they fulfilled their Promise.
