Most parents, having heard about mental arithmetic, want to know at what age can they start practicing? You will be surprised: there is no simple, unambiguous answer to this question. We accept children from 5 to 14 years old! On the one hand, mental arithmetic Indigo Mental gives a concrete impetus to the development of the child, which has its own specifics in each age group. At 5-6 years old, the child improves diction, coordination of movements, he will become more independent and communicative. At 7-8 years old, mental math helps to cope with the large amounts of information that the child encounters at school. Teamwork, the ability to switch between tasks, the ability to work more effectively with information – at this age this is priceless. At 9-12 years old, mental math often becomes a salvation from the dominance of gadgets, in which a teenager can spend almost all his free time. Abacus helps develop (and in some cases return) the flexibility of the brain, pump imaginative thinking and creativity, inspire continuous development and self-improvement. But on the other hand, mental math provides long-term impact, not tied to age and throughout life. In America and Western Europe, mental math is also practiced by older people to prevent multiple sclerosis and Alzheimer’s disease. The brain of a child has enormous potential. In any age group, Mental Math is the best tool to develop this potential from your child’s earliest years!!!
There are two courses:
Addition and subtraction 36 topics Study for 15-24 months Multiplication and division 36 topics Study for 9-12 months What affects the result and duration of the course
– Child’s age
– Cognitive abilities of the child with which he came to class
– Development of imaginative thinking, memory, perseverance, concentration
– Implementation of all our recommendations and completed every homework
All this affects the duration of training. The result for each child will be individual. All children are different and the duration of the course may vary from mastering the topics of the child.
❗️It is important to know: the first positive effect is observed after 1 month. After two full-fledged years of study, children are formed into groups of pros, go to international competitions, olympiads and already count at super speeds and easily solve complex exercises.
The first hours of classes are spent on getting to know Abacus (abacus). Children master functionality, learn to set numbers correctly and perform elementary actions. Children reproduce the image of the Abacus in the imagination with the help of imagination games and then the abacus is gradually removed and the children try to do arithmetic operations already in their heads. Gradually, arithmetic operations become more complicated, and their speed increases. At the same time, the learning process takes place in a playful way, which eliminates rapid fatigue and increases interest in the program. As a rule, the first results of studying mental mathematics are visible after 2-3 months of weekly lessons and daily short homework assignments. But the child will be able to perform elementary mental actions with numbers after the first trial lesson. In order to fully master this mental counting technique, children will need approximately two years of stable practice. In the first year they will master the operations of addition and subtraction of numbers, and in the second year they will master the ability to multiply and divide using mental arithmetic algorithms.
Online platform
Our company keeps pace with innovative technologies. The learning process takes place on a special author’s computer platform designed for children. As a result, our students: They train with great desire on the online platform at home, because for them it looks like a computer game Strongly motivated to constantly train, because special bonuses for solving examples and even a special “secret character” are integrated into the online platform, which can be developed thanks to the solved problems They have access to statistics showing the percentage of correct answers, which motivates them to train more to improve their results They show amazing results and after 3-4 weeks they can count in their heads faster than their peers and even parents, which cannot be achieved without an online platform. Students can use any tablet or smartphone as a “touch” abacus, so they can train without traditional abacus In the program, children also have video lessons available, to which the student can return if for some reason they had to miss classes. Homework is the most important To achieve results in quick mental counting, you need to improve and train your skills daily. This can be compared to the ability to sit on a twine. If you devote time to stretching every day, then every day you will be closer to the twine. It’s the same with speed counting, it’s impossible to achieve a full result by training just once a week. It is important for children to complete daily tasks on the platform in their personal account (about 15-20 minutes), these classes are programmed by the teacher, they do not depend on time, but are mandatory, since with their help, the mental account is gradually brought to the skill level and depends on regular homework child’s progress.
During the 1st month, children learn to work with accounts – Abacus. Practice technique and mental arithmetic. At the 5th-6th month of training in children, both hemispheres of the brain begin to work synchronously, so that they easily count in their heads and can simultaneously recite a poem / sing a song or play a musical instrument. After 12th months, children are easier to concentrate on the task and complete home workouts faster. As a result of the fact that they have already developed photographic memory, imagination and logic. They notice a positive result from their work, this inspires them and stimulates them to further development. After 15-24 month – the end of the 1st course “addition and subtraction”. At this stage, children already know how to quickly count verbally with ease. Their self-esteem and self-confidence grows. Children are happy to demonstrate their skills to others. And after the 2nd academic level of “multiplication and division”, Indigo Mental students take part in international olympiads. And besides, they noticeably “pump”: the ability to think quickly, analyze and make decisions, useful memorization skills in seconds and sustained attention. And if you have not yet made a decision to educate your children in the Indigo Mental Club, contact us and we will provide you with quality advice on classes.
The modern INDIGO platform is an effective tool for daily training. What makes learning interesting and productive. The period of the full course of study contains not only the standard levels of Addition-Subtraction and Multiplication-Division, but also Squaring and Negative numbers.

About the founder of Math Abacus for Kids LTD
Hello, my name is Anna Reshetova, and I am the founder and director of Math Abacus for Kids LTD, operating under the unique “Indigo Mental Club” methodology. My journey with mathematics has been both unusual and inspiring.
From an early age, mathematics presented more of a challenge to me than a natural skill. My mathematical abilities gradually developed through hard work and continuous practice. Transitioning into a class with a deep focus on mathematics marked the beginning of my journey. Despite initial difficulties, I made significant progress by the end of my schooling, thanks to the support of excellent teachers and my parents.
My passion for teaching mathematics ignited during my university years when I began assisting a school student. Just a month into our lessons, I saw substantial improvements in his understanding of the subject. This realization that I could make a difference in children’s understanding of mathematics made me seriously consider a career in education.
Over time, I realized that additional methodologies were necessary for the comprehensive development of children’s intellectual abilities. That’s how I discovered mental arithmetic and the “Indigo Mental Club” methodology. The results were astounding: children who participated in this program showed outstanding achievements not only in mathematics but also in other subjects. This was my chance to make a truly meaningful impact.
Thus, Math Abacus for Kids LTD was founded. Our mission is simple: to love children and our work, aspiring to impart knowledge and skills that will enable them to realise their potential in life. We use revolutionary methods and a special computer program to make the learning process as effective and interesting as possible.
With my experience and love for children, I am confident that every child can achieve remarkable results in their studies and life. Together with a team of professionals, we work to ensure that each of our students can unlock their potential and become true wizards of mathematics.
Yours sincerely,
Anna Reshetova
