JAMS Parents
In their own words
Raaga started at JAMS when she was only 5 years old. Today she is at middle school, and is still a JAMS student. Watch this 2-minute video as Jyothy shares with us that her daughter learned a lot more than just the love for math.
JAMS Parents
In their own words
Gayathri doesn’t have to worry about school math anymore. Watch the 2-minute video to learn why son, a JAMS student for 3.5 years now, is above his peers and have a love for math.



JAMS students, as young as 6 years old, are trained to focus for as long as 120 minutes without interruption!


The direction of the bids, hand positioning, placement of the Abacus are details that matter!


JAMS students are trained to look at a problem and work it out mentally, before diving in and trying to resolve it.


Students learn to be quick on their feet. A timer is used and they are motivated to do faster than last time.


At grade school, our children are at least 2 math levels ahead. This boost their confidence and self-esteem.

Where your child’s future begins
“The sooner kids stop counting on their fingers, the better they are at math later in life.”

“In less than a year Violet succeeded in reaching her goal. She is well ahead of her class in math and is continuing to reach higher goals. Her level of concentration and focus have shown marked improvement.”

Kathi Johnson

“To our Jacob, Abacus is more of a hobby than a study. That’s how much he loves abacus and the enjoyment for math has grown over the years as his ability and skills have improved. We’re very pleased with the JAMS and would recommend it to anyone!”

Angela Lee

“She has now understood that she can always excel at math just like science and languages if she puts the right amount of effort and hard work. We will always be grateful to you for helping our daughter to love Math just as much as her other subjects.”

Frequently Asked Questions

We believe that every child has a unique learning style. At JAMS, our personalized coaching will help your child succeed within the classroom and beyond.

Apart from been strong in China and Japan, these two teaching styles are very different in nature. Kumon focuses on learning through repetition, memorization and discipline. Abacus focuses on visual learning, problem solving and organization. Kumon also focuses on math, reading and writing. Abacus strictly focuses on mental math and a life skill of seen the world through a mathematician’s eyes. You can read our blog post about the difference here.

Students of all ages and math proficiency are welcome to start their Abacus learning at any grade or learning level. Ideally, a student should be old enough to promptly recognize and write numbers from 0 to 9.

Both basic and advanced math problems can be solved with an understanding of the Abacus, including addition, subtraction, multiplication, division, fractions, square root, cube root and others. The mental math calculation also helps children with elementary advanced mathematics at all school levels, including algebra and college-level math.

Our teachers are focused on each child’s personalized learning, and encourage him/her to do their homework independently so we can assess their skills and identify where they may need help. We only request that you commit to carving out time for your child to focus on doing their JAMS homework and encourage their learning journey.

Yes, absolutely! Here is a good example: When you work on addition and subtraction with ten 2-digit numbers, you have to move Abacus beads approximately 30 times. If you make even one mistake, your answer is incorrect. So it is vital to remain focused, which enhances concentration skills.

At JAMS your child will rediscover math. Our personalized teaching helps your child be confident and most importantly, enjoy math.

Abacus will help your child excel in grade school and beyond. A vast number of our students have earned recognition such as TAG, and every single one is at least 2 grade levels ahead of their peers. We have a diverse group of students from across the world who outshine their peers not only in math but also in other disciplines using the skills that they learned at JAMS. Even if you or your spouse are not good at math, we can still help your child excel.

Absolutely not. When your child starts at JAMS, we provide a complete kit including the Abacus for a one-time fee. As a parent you do not need to learn the Abacus to help your child succeed. We only request that you commit to carving out time for your child to focus on doing their JAMS homework and encourage their learning journey.

Our teaching philosophy around mental calculation leverages the Abacus to give our students essential problem solving skills, helps build their focus, persistence and sense of accountability. These are life skills that help them compete and succeed in today’s and tomorrow’s world – and no calculator or computer can teach these skills.

Yes. Focus, persistence, time management, organization and self-driven accountability are key to your child’s success in the classroom and beyond. JAMS parents see their children be more engaged with their schoolwork across subjects, better prepared for tests and be overall more confident and successful than their peers.

“It’s hard to explain the sense of joy I feel when I can help a student overcome a fear of math or when a student is recognized as outstanding in math or TAG by the grade school.

We bring the teachings of Soroban Abacus to help build a solid and strong foundation of Mental Mathematics, focus and confidence. We strongly believe that every student can become an overachiever at JAMS.”
