How To Use An Abacus: A Guide For Kids And Beginners (2026)

An abacus is a counting frame, on which children make calculations by sliding beads along the rods. This guide is for you if you want to help your child or your students learn how to use an abacus and improve their mental math skills and number sense. You’ll learn about different abacus types and how to perform operations like addition and multiplication using an abacus.

Key Points:

• An abacus is a manual counting frame you can use to make calculations using physical beads on rods
• Depending on its position and type of abacus, each bead has a set value, and moving that bead activates that value
• You can use an abacus not only to make simple calculations, but also to perform operations like addition, subtraction, multiplication, and division
• The abacus also improves mental math skills, number sense, fine motor skills, and focus and memory

What Is an Abacus?

An abacus is a manual calculation tool and a counting frame. People used it for thousands of years to perform arithmetic, although its exact origins are unknown.

The abacus definition is a mechanical counting aid, which consists of beads and stones that the person using it would move along the rods. You can think of an abacus as an ancient calculator: long before the electronic calculators we know were invented, merchants, scholars, and engineers used an abacus to handle large numbers quickly.

One way to understand the abacus is to perceive it as the visual map of our decimal system. Students physically move the beads that represent ones, tens, and hundreds, to not only make the calculations, but also develop number sense.

Parts of an Abacus and How Bead Values Work

To understand how abacus works and how you can use it, you must first understand the anatomy of this arithmetic tool. The standard modern abacus, the Japanese Soroban (you can find types of abaci later in the article), is a rectangular frame divided into two sections by a horizontal beam. Other types of abaci have slightly different structures, but the logic behind them is the same. Most abaci are divided into two sections by a horizontal beam.

• The Upper Deck – There is one bead per road; typically, the value is 5. These are known as “Heaven beads.”
• The Lower Deck – Each bid on the lower deck has a value of 1; these are known as the “Earth beads.”

How does an abacus work is through bead manipulation. The beads are only valuable when students move them toward the beam. For example, to represent the number 6, you would move one bead from the upper deck and one bead from the lower deck toward the beam.

Types of Abacus: Chinese, Japanese, and Russian

As abacus counting evolved as a method, the tool underwent some changes as well. Different nations changed it to match their specific mathematical needs. Understanding these types will help you choose the right abacus for your kids.

• The Chinese Suanpan (2/5 Abacus) – In this abacus version, each upper deck rod has two beads (each representing a 5) and 5 beads on the lower deck (each with a value of 1). Each rod has a total value of 15.
• The Japanese Soroban (1/4 Abacus) – Each upper deck rod has 1 bead representing 5, and each lower deck rod has four beads representing 1. Each rod can thus represent the numbers 0 to 9, mirroring the base-10 system used in modern math.
• The Russian Schoty (10-Bead abacus) – This abacus looks different, as it features 10 beads in a single row. The bottom rod represents ones, the rod above represents tens, and so on. Each bead on each road has a value of 1. This abacus is more intuitive, especially for younger learners.

How to Set up an Abacus (Zeroing)

To set up an abacus, you should:

1. Position it flat on the table or in the position your child uses it
2. Move the beads away from the beam (in the case of abaci like the Japanese Soroban and the Chinese Suanpan) so that no bead is touching the beam. In the case of the Russian Schoty, the “zero” position is when your kid moves all the beads of each road to the right side.
3. The abacus will be set up at zero and ready to use. 

How to Count on an Abacus

The main secret of using an abacus for math and counting is the rods, which function like columns in numbers. 

When counting on the Japanese abacus, your child needs to always start on the far-right rod, which is the Ones place. As they move to the left, each rod increases in value by ten. First, they have Ones, then Tens, then Hundreds, and so on. Here’s how to count:

• To represent numbers 1 through 4, your child simply slides the lower beads up to the center beam one by one.
• Once they hit 5, they slide down all the lower beads and bring one upper bead to the beam (upper bead equals 5).
• They can keep counting up to number 9 on the same rod. 

Then comes the most important part of the abacus math for kids, the trade. Once a rod is full, your child needs to move to the next rod on the left. Here’s an example of counting to 14 step-by-step:

• Count to 9 as described
• Clear the rod entirely
• Push 1 bead from the second rod (Tens rod) up to the beam
• Back to the first rod, and slide up the four beads that indicate 1

The abacus will now show 1 Tens place and 4 Ones place, totaling 14.

How to Do Addition on an Abacus

Making an addition on an abacus, in the case of simple problems like 2 + 2, is pretty straightforward. However, when your child needs to “carry” a number to the next rod, things may get tricky. Let’s work through the example of 7 + 3 = 13 step by step to see how to use abacus for addition.

1. Represent 7 on the right-most rod by sliding down one upper bead (value of 5) and sliding up two lower beads (value of one each)
2. You only have 2 lower beads left on the first rod, so to represent the number 6, you need to use the Tens value rod
3. Think of 6 as 10 – 4. Add one to the tens rod
4. Then, subtract the 4 from the current rod (as your child currently has 7 there, they need to bring up the upper bead (7 – 5 = 2) and bring up one lower bead (2 + 1 = 3))
5. Your child will be left with 1 bead on the Tens rod and 3 beads on the Ones rod, with a total of 13. 

Your child won’t just be doing mental math here, but will use their logic and memorize number partners.

How to Do Subtraction on an Abacus

Subtraction with an abacus, on the other hand, is the process of moving beads away from the central beam. For subtraction, your child will also need to use “partner” rods when they don’t have enough beads. Let’s look at a worked example of 13 – 7 = 6.

1. Your child needs to represent the starting number 13 on the rods. In this case, it will be one lower bead from the second rod on the right (Tens rod) and 3 lower beads on the first rod on the right (Ones rod)
2. Students need to subtract 7, but on the ones rod, they only have 3 beads
3. Since they can’t subtract 7 from 3, your child needs to go to the tens rod and slide that one bead away from the beam. They have now subtracted 10, but since 10 > 7, they took 3 beads too many
4. They need to go back to Ones rod, and add 3 using the 5-bead shortcut
5. They’ll get 6 as the answer (one upper bead of 5 and 1 lower bead of 1)

How to Do Multiplication on an Abacus

At the beginner levels, learning multiplication with an abacus is similar to doing high-speed repeated addition. Your child can start multiplying by adding the same number several times. Let’s solve 6 x 4 = 24.

1. In 6 x 4, your child will need to add the number 6 to the abacus 4 times
2. On the ones rod, they set a 6 by bringing one upper bead down, one lower bead up. 
3. They have 3 beads left, so to add another 6, they add one bead on the 10s rod and subtract 4 from the ones rod (since 10 – 6 = 4). They’ll have 12. 
4. Add another 6 on the ones rod to get 18. 
5. Again, use the tens rod to add 10, then subtract 4 from the ones rod. You get 24, as 10 + 10 = 20 (Tens rod), and 8 – 4 = 4 (Ones rod). 

How to Do Division on an Abacus

Division on an abacus, as you may have guessed, is then a repeated subtraction. Essentially, your child needs to calculate how many times they can take a small number out of the big number. Let’s solve 12 / 3 = 4 using an abacus:

• Start with setting up 12 on the right part of your abacus, using one bead on the tens rod, two on the ones rod
• Choose a counting rod. This can be the rod on the far left to keep track.
• Do the first subtraction of 12 – 3. Since you can’t subtract 3 out of 2, borrow from the 10s rod. Since 10-3 = 7 and 7 + 2 = 9, you are left with 9. Move one bead up on your counting rod.
• Subtract 3 from 9. You are left with 6. Move a second bead up on the counting rod.
• Subtract 3 from 6. You are left with 3. Move a third bead up on the counting rod.
• Subtract 3 from 3. You are left with 0. Move a fourth bead up on your counting rod.

The counting rod will show 4, which is the answer.

Benefits of Learning the Abacus for Kids

Learning how to use an abacus for kids is beneficial for several reasons:

• Over time, children will learn to visualize the beads in their minds and perform calculations in their heads, improving their mental math skills. 
• Children must remember the beads’ positions and their last actions to solve the problem at hand. This trains their memory and also keeps their attention in the process, developing focus.
• Every step in an abacus represents a value, and children constantly interact with ones, tens, and hundreds. This helps them develop an intuitive understanding of place value.
• As your child solves math problems using only their hands and their mind, they will become more confident in their skills and more positive towards other math aspects.

At Brighterly, we love tools like the abacus because they make math tangible and engaging for children as part of a math program for kids that we offer. Our elementary math tutors often use similar visual and interactive activities during 1:1 math tutoring sessions to help students understand core math concepts better and enjoy the learning process.

Frequently Asked Questions (FAQ)

What Age Should a Child Start Learning the Abacus?

Ages 4-5 are a great place to start to learn basic abacus counting. At this age, it helps develop their fine motor skills and connect the one-to-one correspondence of beads to numbers. You can move on to teaching them to perform operations at ages 6-7. By this time, they have developed the number readiness to understand place value.

Which Abacus Is Best for Beginners?

Japanese Soroban (1 upper + 4 lower beads) is the most commonly used and recognized abacus today. Because each rod has enough beads to represent numbers 0-9, it fits the base-10 numerical system perfectly. This makes sense for children naturally and helps to avoid additional confusion.

Can a Child Learn to Use an Abacus on Their Own?

Children can explore the beads and play around independently, but to understand the technique, they will initially need some guided practice. Trading and borrowing follow specific rules, and the beads have pre-determined values, so they need some parent-led sessions to learn the rules and the logic behind the steps.

How Long Does It Take to Learn the Abacus?

With regular, 15-minute practice sessions, learning the basic operations like addition and subtraction well will typically take a few weeks. For more complicated operations, like addition and subtraction of larger numbers, as well as visualizing the abacus without touching it, may take several months of consistent training. 

Does Learning the Abacus Improve Mental Math Skills?

Yes. A 2020 research by C. Wang shows that this abacus training significantly improves working memory and numerical magnitude processing. With an abacus, numbers and operations turn into visual patterns, and children find the solution by dissecting the numbers, understanding them better in the process. 

Is the Abacus Still Used Today?

Yes! While not used as much as in the past, the abacus is still widely used in early math education across the US, Japan, and China. It’s also a primary calculating tool in mental math competitions.
