"Technology Tickets". Each Sunday give the kids 10 tickets. Each ticket = 30 minutes of t.v., game system, computer, etc. Tickets can be used consecutively, but when they are out they are out for the week. Parents still reserve the right to say "no" even if they have a ticket. LOVE it.
Great ideas on how to make your little ones a cleaning kit and get them involved with the chores early on. If you start them young and convince them cleaning is fun, it will pay huge dividends in the future!
