Put a good stash of coins into a closed paper bag.  Boys sit in a large circle and pass the bag around until the leader signals stop.  The boy holding the bag pulls a card from a pile held by the leader and reads what’s on it: e.g. a toy car for brother cost $1.35.  Then, without looking into the bag, the boy must stick his hand and pull out the correct change to buy the gift.  Make sure that all gifts are under $2.00.   The boy then returns the money to the sack and the passing starts again.
