I use textbooks that are regarded as college preparatory by CA schools and UCOP. Each student is expected to obtain their own copy of the student edition textbook for the class. This helps me keep my prices as low as possible.
Students are expected to bring their own textbook, notebook, graph paper, pencils, and calculators to each class. Geometry students also need their own protractor, compass, and ruler. I recommend students obtain a Ti-84 graphing calculator, however any scientific or graphing calculator is acceptable as long as the student learns how to use it.
