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. Not to do "allowance" for chores, but rather teach chores/responsibilities as how they contribute to family. Interesting perspective.
start the new year with a new behavior system that builds on the positive and helps establish routines!
