This lesson plan discusses cylindrical and spherical coordinates over two days. Day 1 focuses on cylindrical coordinates, defining them, providing examples, and having students complete practice problems converting between cylindrical and Cartesian coordinates. Day 2 introduces spherical coordinates and how they relate to cylindrical coordinates with more examples and problems combining the two systems. Students will work with partners to complete practice problems. Assessment will be with a paper-and-pencil test. For homework, students must find an equation relating the three coordinate systems. The goal is for students to understand and be able to work between the different spatial coordinate systems, especially as they apply to engineering and building constructions.
