You must head over right now to get this FABULOUS Polar Express Unit
I love love the Polar Express. I set up our "train" in a storage closet and we listen to the recording. It is dark and a little bit cold in there, so it is perfect for this activity.
In addition to a bell taped under their chairs, I also make them a ticket. I have a parent volunteer make hot chocolate while we are gone. The children are amazed! :)
