The sandboard is a flat board with fine sand on it, on which people can write, draw and perform calculations using a wooden stick. The various types of abacus from different cultures throughout history can be roughly divided into three categories: sandboard, counting board, and beaded abacus.

From existing literature, it can be seen that many ancient civilizations had their own calculation tools similar to the abacus. It is worth noting that the term “abacus” does not only refer to the Chinese abacus. This is why it is called the “mao abacus.” The third type is the teaching abacus, which has soft bristles on the rods so that the beads can be placed in any position, making it easier for teaching. The second type has one bead on the top section representing the value of five, and four beads on the bottom section representing the value of one. The first type is the traditional abacus, which has two beads on the top section of the beam representing the value of five, and five beads on the bottom section representing the value of one. Korean abacus (Jusan): Similar to the Chinese abacus but with fewer beads.Įach type of abacus has its unique features and methods of use, but all of them are designed to perform calculations and help develop mental arithmetic skills.įrom a practical perspective, there are only three main types of Chinese abacus. Nepalese abacus (Soroban): Similar to the Japanese Soroban, but with a larger frame and fewer beads. Indian abacus: Also known as the “ Salamander Abacus,” this type of abacus has two decks of beads, one for units and the other for tens, and is used for simple arithmetic calculations. Russian abacus (Schoty): A rectangular frame with vertical wires or rods, and beads sliding on them.

Japanese abacus (Soroban): Similar to the Chinese abacus but with a different shape and arrangement of beads. Trains child to be disciplined, patient and confident.There are several types of abacus used around the world, including:Ĭhinese abacus (Suanpan): The most widely used abacus, consisting of a rectangular frame with beads sliding on rods.Enables child to do mental calculations that involve single digits and complex mathematical formulae.Builds a child’s mental calculation skills, providing him or her with the ability to use traditional calculation tools to reach scientific educational results.Progressive training in understanding numerical concepts in a stress-free environment.Aids the development of the left and right brain through use of mental imagery to calculate and do sums.The coordinated use of the brain, eyes and hands sharpen a child’s memory and concentration power.

With the use of the right techniques that tackle complicated mental calculation, the programme sharpens memory and concentration abilities.Ĭore Benefits of Crestar’s Abacus and Mental Arithmetic Course: Developed exclusively for Crestar Learning Centre by abacus experts from Taiwan, our Abacus and Mental Arithmetic Course is designed to maximise every child’s mental agility.
