When teaching anything, students have a tendency to shine in other ways than that of the traditional pen and paper test. This project was used in place of a traditional pen and paper test. My students created a bird house for their chapter project that covered parallel and perpendicular lines and planes. They had to design their houses from scratch, making sure that the bird they selected could actually live in it. They came up with blue prints, calculated surface area, and even wrote an essay. When they actually had to build the birdhouse, they had the option of actually building one that a bird could live in or create it out of legos, a pepsi box, or what ever materials that they could find. The requirement was that the work had to be original and had to be the exact size for their bird, regardless if it could live in it or not. The other thing was that I gave them the option of keeping their houses or donating them to a local organization.
