Meet the Team at Mathnasium of Tri-Cities

Larry Martinek

Larry has spent his entire career finding a better way to teach math. From inner city public schools, to acclaimed magnet schools, to leading private and parochial schools, Larry has served as both a classroom teacher and as an educational consultant. He has designed curriculum, teaching strategies, and teaching materials to help students and teachers learn math more effectively. He has trained teachers in the art and science of boosting students' ability to “do” math, thereby increasing students' math scores and feeling of self-worth. Larry is the developer of Mathnasium’s educational program – one of the most comprehensive and innovative curriculas ever produced for teaching math. While Larry is not an Instructor at our Centre, he is a valuable asset we can call on to ask about specific students' scenarios for guidance and advice. This has helped to make visits more productive and enjoyable for many of our students.
