Mr. Commander

Welcome to the 2021-2022 school year! My name is John Commander and I teach math and computer science here at Oakcrest. I have been teaching at Oakcrest since 2010 and am very excited to start my twelfth year. This year I will be teaching three courses: Algebra 1 with my coteacher Ms. Moss, Geometry with my coteacher Ms. Tantum, and AP Computer Science Principles. Use this website as well as Google Classroom to keep track of due dates for upcoming assignments, projects, and tests/quizzes. I look forward to keeping in touch with students and parents and making this a successful school year.
