The theme of the course will be three-dimensional geometry. The approach will be hands-on and problem-centered, with lots of model making. The goal is to learn geometric visualization and methods of computation in three dimensions. We'll study polyhedra: projections and slices, volume and area, solid angles, dihedral angles, decompositions, space filling, and symmetry. Special topics include Platonic solids, Archimedean solids, spherical geometry, crystal structure, and geodesic domes.

There is no required textbook or software.

Grading policy
There will be two exams and a final project. There will be no final exam. Homework will be assigned every class. (There will be short assignments Tuesday to Thursday, and longer assignments Thursday to Tuesday.) Late homework will not be accepted. Your grade will be based on the exams, project, homework, and class participation. The two exams will count 20% each, homework will count 30%, and your project will count 30%. (Class participation will be considered in borderline cases.)
