Nothing inspires kids of any age to clean like the promise of something special upon completion. If you want to put the pedal to the metal, offer up a "Beat the Clock" game. Set a timer for a reasonable amount of time and make a deal with your kids -- if they can clean up their rooms to your satisfaction before the time goes off, they get a special treat. The time limit should help keep them focused on the task. Young kids may respond to some kind of sweet treat, maybe a trip to the ice cream shop. Tweens and teenagers might appreciate a sleepover, a later bedtime or a trip to the mall with their friends. Some may call it bribery, but we like to think it's just good sense.
