From the author

The manual is written by a teacher of mental arithmetic, chief methodologist, Director of education at the center for mental arithmetic. The author participated in the development of the method of mental arithmetic when it first appeared in the CIS countries. After analyzing the market, I noticed that former colleagues who also became professionals in this field began to open companies, centers, associations that issue certificates in mental arithmetic online training for teachers in mental arithmetic. They realized that the franchise is expensive, and it became cheaper to teach this course themselves.

This book covers most aspects of teaching mental arithmetic so that teachers can teach and develop students using mental arithmetic without going through expensive training, online courses, and even more so without franchises.

Introduction

This manual is designed to train teachers in mental arithmetic, for managers of children’s centers and other professions related to the training of mental arithmetic. With this book, you can learn all the formulas of addition and subtraction, multiplication and division, learn the method of explaining this course to students, the organization of the teacher’s work (lesson plan, working with parents, exams, Olympiads, standards, reports of the teacher, etc.).

After carefully studying the material, the teacher will be able to achieve excellent results for students, that is, to study the course of mental arithmetic, the teacher will not need to take expensive online or offline courses, buy a franchise.

Also in the introduction, I want to specify the basic concepts.

Mental arithmetic is a method of rapid verbal counting (faster than a calculator counts), based on calculation on special accounts — soroban. Learning to count on the soroban, students will begin a mental count.

Mental score. Students present a soroban in front of them and quickly count on imaginary accounts. It is the mental account that develops both hemispheres of the brain: representing soroban works the right hemisphere, translating the image into numbers works the left hemisphere. In other words, logic, creative and analytical thinking, photographic memory, speed of reaction, and self-confidence increase. The lessons of mental arithmetic use flash cards that develop tasks, dictation by ear, mental dictation, relay races, which also develop fine motor skills of the hands, both hemispheres of the brain, auditory and visual memory, and as a result, improve grades in all subjects.

1. Methods of teaching students

1.1 Fundamental exercises (FE)

Fundamental exerises — examples that you need to perform every day to develop your fingers, to increase the speed of solving examples, in the future, they will also help in the transition to a mental account. They change depending on the topic, the formula passed in the lesson. Fundamental exercises must be perform
