We are fortunate to have discovered JAMS, and grateful to Miwako Sensei, who instills discipline and motivation in her pupils.”
-Karen C., Parent

You may think JAMS is just about learning the abacus, but we are about so much more!
It is Sensei Miwako’s goal to help develop the whole child.

JAMS encourages and fosters:

Our students perform at higher levels and can do things that their peers (and even parents) cannot! They see their progress and take great pride in their accomplishments.

JAMS students are taught to sit properly and work quietly for an hour or more without interruption. This repetitive course enhances their focus and ability to self-regulate.

We remind students that mistakes happen because they are challenging themselves. They see that the harder they work, the more they can overcome limitations.

Students work on their own, going at their own pace. They are in charge of their own success.

Students are responsible for being completely ready for class. They take responsibility for their own role in their education.

JAMS students address teachers as “sensei” using polite language. They work quietly, respecting their classmates and teachers.

At JAMS we want our students to excel not only in math, but in every aspect of their academic and social lives. We hope the part we play in their learning will benefit them for a lifetime.

JAMS is proud to be the only Abacus math school in Portland and in the State of Oregon certified by the League of Soroban of Americas. Since 2001, we have dedicated to Abacus & Anzan instruction and to building a strong foundation of Mental Mathematics along with lifelong skills. JAMS empowers children to achieve academic success, so they will grow in areas that go well beyond the classroom. JAMS parents can expect their child to improve in 5 different areas: concentration, discipline, problem-solving, time management, and confidence. This is the teaching approach at JAMS since opening its doors.
