Use Public Spaces to Teach Symmetry

My wife and I recently were blessed to visit Paris, and spent an afternoon at La Grande Arche, Paris, which houses government offices.

I videoed a short clip about using public buildings in any city to teach symmetry and other math topics. La Grande Arche (in French, 'The Big Arch') exhibits both reflectional, or mirror, symmetry and rotational, or point, symmetry. Lots of other public buildings offer similar opportunities for investigating this sort of math topic.
