Do everything without whining, complaining or arguing. Start off the week with a set amount of quarters in each jar. If they are caught whining, complaining or arguing they lose a quarter. At the end of the week, they get the money that remains.
I love this - Neat rewards system. 31 quarters in the jar at the beginning of the month, every day that they do not do their chores, they lose a quarter. Whatever is left at the end of the month they exchange for cash and the quarter jar is refilled.
