577- Proportional Reasoning, Pick's Theorem, and an Open-Source Graphics Tool

Pick's theorem is a method for calculating the area of complex polygons by relating points inside the area of a grid to those on its boundary. The open-source graphics editor GIMP allows users to do this with remotely sensed images. This demo ties to proportional reasoning, geometry, and student's understanding of geography.
