Every week, the kid starts with a balance of whatever allowance you decide, say $50....each chore, homework, getting out of bed to get to school, everything that makes an adult responsible has a value....
Homework not ready for the next day's school...2.00
Getting up late....2.00
Not washing the dishes....5.00
If they are responsible, they end the week with $50, if not, then whatever is left.
Their allowance is their pay to purchase the things they want..
"I want a new pair of sneakers!" Well, that's $100, two weeks allowance. In the long run, it pays...you stop having to buy all the crap that catches their attention and they learn that if they really want it, they will have to be responsible. It works really well when there are more than two kids. I have a few, so when the oldest would see that the younger siblings were walking away with the full-boat allowance, it motivated them. Nothing serves as a better motivator for a kid than sibling rivalry.
