Founded in 2001, JAMS is proud to be the only math school in the Portland and Beaverton area certified by the League for Soroban Abacus. We use the teachings of Abacus & Anzan instruction to build a solid and strong foundation of mental mathematics with lifelong skills. Mental math calculation is a skill that children retain for life. Abacus gives any child the skills and confidence to excel in STEM-related subjects beyond the classroom.
