◆◇◆ Comments from the Editor ◆◇◆

To use an abacus, you look at the beads and flick them with your fingers, and determine the answer by looking at the number of beads.

The fingertips are sensory organs directly connected to the brain, and are often referred to as "an external part of the brain." Abacus learning, which involves transmitting visual information to the brain, and then repeatedly verifying it with your fingers, not only cultivates mathematical reasoning, but also stimulates the brain.

Furthermore, the abacus stimulates the right brain, improving memory, and repeated calculations cultivate concentration and perseverance.

Furthermore, practicing the ability to instantly arrive at answers fosters judgment and information processing skills.

The abacus is not just a tool for calculations, but also plays a role in ability development and image training.

Ishido Soroban Academy, which teaches the Ishido-style abacus, was one of the first to recognize this potential of the abacus. The Ishido-style abacus involves thinking about the abacus beads in your head, practicing calculations while imagining them, and developing individual abilities through an original curriculum that allows students to improve step by step and effortlessly.

This book is intended for parents to teach their children abacus at home, and uses the Ishido-style method for explanations. Even parents who have never used an abacus before can easily understand the explanations, leading to improved abilities in their children.

We hope that this book will help children to discover their infinite potential.
