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.
Chore Pins/Magnets- Kids choose the job and how much it's worth. At the end of the week, total amount is how much allowance they receive. Maybe at the end of the week if there are some left divide them up for no pay, that way they all get done.
Write a letter to your child or grandchild each year and include money for grad gift. I like this idea of writing a letter, and even adding money, but I think it'd be better to go longer than a grad gift. Wedding, first home, first child?
Good idea for kids. Clutter Busting Game using ping pong balls-Each person chooses a ball, completes the task, then chooses another one. After 30 minutes, whoever has the most balls gets a prize -- like a no-chores day, or gets to pick a movie.
