SO doing this for my kiddos someday... send Oh, the Places Youll Go by Dr. Seuss each year on the last day of school. Dont tell your kids and let them read 13 years of messages on their graduation day!
"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. Loss of ticket for consequences - talking back, fighting, etc.
