If you're looking for a great dance to teach this time a year, I have a simple, easy-to-do one for you. It's called the Jingle Bells Dance, obviously it is performed to the popular holiday song, Jingle Bells. The nice thing about the Jingle Bells song is that it is a non-religious holiday song. Most people think of Jingle Bells as a Christmas carol, however the song itself is about a sleigh ride through the snow, with no mention of Christmas. So the song really is about celebrating winter without attaching any religious significance. Below is a description of how to perform the dance. I've done this dance with 1st grade through 6th grade, but you can basically do it with any level. Best of luck with it.
The Jingle Bells Dance
Have the dancers form pairs and stand in a double circle (concentric circles) with the inside partner facing out and the outside partner facing in, hands joined. Begin with both partners going counter-clockwise (CCW). The outside partner will travel to the right and the inside partner will travel to the left.
