UCMAS mental calculation system

UCMAS, utilizing an innovative computational system and employing the abacus, synchronizes the activity between the right and left hemispheres simultaneously, enhancing mental capacity and skills such as time management, focus, and problem-solving abilities. These skills play a fundamental role in the success of students in all fields and everyday life.


This educational system consists of 10 main levels and 2 preliminary levels. Each level's learning process takes three and a half months, with one session per week lasting two hours. It is designed for students between 6 to 8 and 9 to 13 years old who have the ability to read, write, and perform addition and subtraction operations with numbers 1 to 9. The instructional tools and materials unique to this system include:



  • Student abacus (Soroban): Consists of 17 rods with one bead at the top and four beads at the bottom used for calculations.

  • Textbooks (full-color): 2 main textbooks and 1 practice book.

  • Audio CD: Enhances students' accuracy and speed in mental calculations.

  • Speedwriting notebook: Increases students' speed in problem-solving, accelerating the learning of new concepts.

  • Listening notebook: Highly effective in improving students' concentration and accuracy.

  • Flashcards: Enhance mental visualization and repetition, strengthening both short-term and long-term memory.

  • Student bag: Used to standardize and organize students' materials.


It's worth mentioning that the UCMAS developmental program not only complements the mathematical education in schools but also teaches students mental visualization techniques through the mentioned tools and materials.


Origin of the Abacus:


The word "abacus" has Greek origins, derived from the word "abax," meaning counting board. Historically, the first abacus was invented in China 500 years before Christ. However, the more advanced version of it, the one used today, was introduced approximately 1300 years after Christ in China.


Even today, Asian shopkeepers still use the abacus for their calculations. Japan, being one of the largest producers of modern electronic devices, is a notable example. The first thing that catches the attention of travelers in Japan is the use of the abacus by Japanese shopkeepers. They swiftly calculate the prices of goods using the abacus and their skillful hands.


Structure of the Abacus:


The abacus consists of a frame (made of wood or plastic) with several vertical rods inserted into it. Each of these rods holds a number of beads, which, by moving the beads up and down the rod, allows for the calculation of digits. Additionally, a horizontal rod divides the interior space of the frame into two parts called the upper and lower decks.


Abacus Components:


To use the abacus, it is placed on a flat surface such as a table or held by hand, and all the beads on both the upper and lower decks are moved towards the opposite direction of the horizontal rod. The numerical value of each bead in the upper deck is 5, while in the lower deck, it's equivalent to 1. When the beads are moved towards the horizontal rod, they are effectively counted.

Philosophy of UCMAS

UCMAS is a combination of an ancient teaching tool - the abacus - with modern educational skills for the dynamic evolution of the child's entire brain, promoting learning and specifically, mathematical learning, as an excitement and entertainment. This educational program has been developed for years and has been repeatedly tested, resulting in a global experience accompanied by success. However, at the same time, we continuously update our programs and teaching methods to ensure that UCMAS provides the most effective learning experience for students.

How to hold competitions

Noandishan Institute, by holding UCMAS competitions at the provincial, national, and international levels, has taken a significant step towards enhancing the academic level of students, encouraging reading, and fostering a sense of competition.


In the provincial stage, students from each province compete with each other at different levels. The winners of this stage advance to the national competition and strive in a thrilling contest to achieve the top title. National winners also have the honor of participating in the international competition, where they compete internationally against outstanding students from around the world.


UCMAS competitions offer more than just a simple contest; they provide a rich experience for students. These competitions provide an opportunity to strengthen skills in mental arithmetic, concentration, memory, problem-solving ability, self-confidence, and self-esteem for students. Moreover, UCMAS competitions serve as motivation for further learning and achieving national and international honors.


In addition to the mentioned benefits, participating in UCMAS competitions provides an opportunity to meet outstanding students from across the country and the world and form new friendships. These valuable experiences broaden students' perspectives on the world and strengthen their social skills.


UCMAS competitions are a gateway to honor and an opportunity for students to blossom their talents and reach the peaks of success.


Some examples of the achievements of Iranian students in UCMAS competitions:



  • Achieving the first place in the UCMAS World Competition in 2018

  • Achieving the second place in the UCMAS World Competition in 2019

  • Achieving the third place in the UCMAS World Competition in 2020


These achievements demonstrate the talent and ability of Iranian students in the field of mental arithmetic, and their prominent presence in UCMAS competitions heralds a bright future in this area.
