Larry Martinek

Chief Instructional Officer, Developer of Mathnasium Program
Larry has spent his entire career finding a better way to teach math. From inner city to 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 designed to help students and teachers learn math more effectively. He has trained teachers in the art and science of boosting student’s ability to “do” math, thereby increasing student’s math scores and feelings of self-worth. Larry is the developer of Mathnasium’s educational program – one of the most comprehensive and innovative curriculums ever produced for teaching math. While Larry is not an Instructor at our Center, He is a valuable asset we can call on to ask about specific students scenarios for guidance and advise. This has helped to make visits more productive and enjoyable for many of our students.

Our Mathnasium Mission

Teach children math so they understand it, master it, and love it. Math can change their lives, and they can change the world.

What I love about Mathnasium is the ability to teach problem-solving skills and make math make sense, while also making a student smile.
