Dance Instruction Manuals

These dance manuals fascinate me in their ability to bring a little of the past actually to life. Here is a great resource, 75video clips "arranged by historical period, ...demonstrating specific dances or movements."

Classroom idea:
1) Enhance students understanding of historical time period being studied by using these videos to learn a dance.
2) Compare and contrast dances in history. What changed? why?...
