Gain the Skill to Mentally Visualize and
Understand the Composition of Numbers

Soroban, the Japanese abacus, cultivates creative minds and calculation skills.

Students will develop how to visualize and calculate the number compositions in their head.

People who learned the instrument calculate expressions mentally through visualising the beads in the head of a soroban. For example, when calculating the expression 15+6, they will add "1" of "6" at units and flick up “5” and add a bead to the tens-digit to add a new 10. The calculation total then becomes "21". This practice prompts them to visualize the addition of numbers. Why memorize the equations such as 3 + 9 = 12 or 7 + 8 = 15, when it's so easy to calculate mentally using the Soroban (the abacus).

The never before seen Tamaishiki soroban learning is also effective for
right-brain development.


Tamaishiki Ee Soroban utilizes ICT which enables students to acquire calculation, imagination, and concentration skills through an unprecedented learning technique. This activates the right-brain by sharpening visualization and muscle memory. By learning how to use an abacus from an early age, you can develop your "creative mind". With Tamaishiki Ee Soroban, students' concentration skills will be cultivated through rigorous training of accurately processing and quickly responding to mathematical questions.
