"Technology Tickets" Each Sunday give the kids 10 tickets. Each ticket = 30 minutes of television, computer, etc. Tickets can be used consecutively, but when they are out they are out for the week. They lose tickets for talking back, fighting, etc.
Kids need guidance, and that's where the parents come in. Their school can't teach them everything, there are a few things you need to teach to your children yourself, like these important things that will change their personality & make them more disciplined when they grow up.
