[Edu-sig] Confused how teach geometry and importance of teaching geometry in 21st century.

[Maria Droujkova]

Check out GeoGebra OER community. There will be a US conference this year,
and the online resources and groups are good, too.

A lot of my students appreciate geometry through the following lenses:
- Origami
- Computer graphics, especially programming cool visuals for games
- Escher, Dali, and other "surreal" space transformations - we are doing a
lot of it in our "Alice in Wonderland" class, hehe.

We watch videos a lot, too.

Make math your own, to make your own math.
