Larry Martinek, Principal Educational Advisor (Headquarters)

More than forty years ago, math educator Larry Martinek was inspired to find a better way to teach children math. 

As a classroom teacher, teacher-trainer, and consultant in public and top private schools—Larry possessed a uniquely comprehensive view of education. He saw a troubling theme in mathematics instruction: a serious disconnect between the students’ basic skills training and the curriculum they were expected to master in the years to come. They weren’t being prepared properly for their future.

Larry set out on a mission: to find an approach that would provide children with the strong foundation they needed to succeed. Over the next three decades, he painstakingly developed and assembled a blend of methods and materials. Instead of relying on traditional rote memorization and repetitive exercises, Larry’s work focused on helping children understand math by honing their math instincts and getting them to think like mathematicians.  

Today, more than 40 years after Larry first developed it, the Mathnasium Method™ is providing children all over the world increased confidence, critical thinking skills, and mathematical ability to last a lifetime
