Check out Norad Santa on the web!
The website itself has a new game everyday in the Countdown Village. The website counts down to the day that Santa begins his journey around the world delivering toys to the good girls and boys! On Christmas Eve both the website and the app will track Santa via Google Earth on his trip around the globe.
The app has the countdown as well as a game of Elf Toss. There are apps for both iPhone and Android, search for Norad Tracks Santa.
Remind the little ones that the countdown is until Santa leaves the North Pole to begin his journey, you must add one day for Christmas Day!
