Outdoor Quadrilaterals

Inspired by John Johnston's post, I borrowed some GPS devices from Geography today and took a small class out onto the astroturf, where they tried to draw giant quadrilaterals.

We ended up being rather short of time, and had a few technical problems, but a good time was had by all and the students had to think about the properties of quadrilaterals in order to be successful. I'll hopefully have a google map to add to this post on Monday.

Here's the map.
