China abacus

Types of china abacus

China abacus, also known as the Suan Pan, is a traditional counting tool that has been used for centuries. It consists of rods that are strung with beads, and it aids in performing mathematical calculations such as addition, subtraction, multiplication, and division. The abacus is a valuable educational tool for enhancing mathematical skills, improving concentration, and developing memory. It comes in various types, each with distinct features and designs that cater to different computational needs and cultural preferences. These include:

• Chinese Suan Pan

  This is the traditional abacus used in China. The beads on each rod are subdivided into two sections. Each rod represents a digit, and calculations are made by moving beads up and down. The Suan Pan is designed for complex calculations, featuring two upper beads and five lower beads per rod, allowing for addition, subtraction, multiplication, and division. It is widely used in Chinese schools and businesses.

• Japanese Soroban

  The Japanese Soroban is similar to the Chinese Suan Pan, but it has a different bead configuration. Each rod has one bead in the upper section and four in the lower section. The Soroban is used for basic calculations like addition, subtraction, multiplication, and division. It's popular in Japan for teaching mathematics to children and is used in businesses for accounting and finance tasks. The bead arrangement allows for quick, efficient calculations, and many people who use it develop excellent math skills.

• Russian Schoty

  The Schoty is a Russian abacus that has ten rods, and each rod has ten movable beads. Five beads are colored red, and the other five are white. The Schoty is used for addition and subtraction. The red beads represent numbers from one to five, while the white beads represent the numbers from six to ten. It is often utilized by children in schools for simple math operations and by adults in shops for sales calculations.

• Philippine Abacus

  The Philippine abacus, locally known as the "Suanpan," is similar to the Chinese Suan Pan but has distinct features. It has a wooden frame with rods that are strung with beads. The beads are usually made from wood or plastic and are colorful. The Philippine abacus has two beads in the upper section and five beads in the lower section. It is used for addition, subtraction, multiplication, and division. The Philippine abacus is popular among students for learning math and is used by vendors for keeping track of sales.

• Chinese Abacus for Kids

  This abacus is designed for children and has bright colors and fun shapes to make learning enjoyable. It has simplified features compared to the traditional Suan Pan, with fewer rods and beads. This makes it easier for young learners to grasp basic mathematical concepts. The Chinese abacus for kids is used in primary schools and tutoring centers to introduce children to the world of mathematics.

How to choose china abacus

When choosing an abacus for sale, one should consider the material, age group, and educational level.

Abaci are commonly made from wood, plastic, or metal. Wooden abacuses have a classic look because they are made from bamboo or hardwood. They are durable and eco-friendly. A China abacus made from wood is ideal for customers looking for a traditional design that will last long. A Chinese counting tool made of plastic is lightweight and easy to use. It is perfect for younger kids because they can handle it better. An abacus with metal rods is strong and works well for tough calculations.

One should choose an abacus based on the intended age group of the users. Abacuses designed for younger children usually have bright colors and simple designs. They include extra learning materials like charts and guides. Those meant for older kids have more beads and rods. They are used for complex calculations like fractions, percentages, and division. It also comes with exercise books.

Different education levels require different abaci. For primary school kids, buy an abacus with a maximum of 2 rods for addition and subtraction. A 5-row abacus is good for learning simple counting and number values. It allows students to move beads quickly and practice easily. For more complex calculations like multiplication and division, get a Chinese abacus with more rods. It has 7 or more rows, which is useful for advanced math.
