Geometry Session 1: What Is Geometry?
 

In this session, you will use mathematical communication and geometric thinking to solve problems. You will use paper folding as a construction tool because of its visual and kinesthetic properties. (Paper folding is more intuitive and taps into geometric reasoning more easily than traditional straightedge and compass constructions.) The session ends with some reflection on the basic objects of geometry and the difference between an ideal mathematical object and its representation.
