How to Use an Abacus | Teaching Basic Math Operations

The abacus is one of the most beneficial tools for learning mental addition, subtraction, multiplication, and division. Not only does learning how to use the abacus lay the foundation for mathematical development, but it also enhances cognitive and mental skills. The abacus fosters a deep comprehension of number systems and operations, allowing for improved arithmetic practice. Additionally, the process of thinking through different calculations increases your child's logical thinking and problem-solving abilities.

Using the abacus is fun, tangible, and visual, making arithmetic learning very engaging. If I had grown up using the abacus, I would have loved math much more because it would have given me confidence in my mental math skills. The goal of this article is to provide you with strategies, activities, games, and additional resources to teach abacus use effectively and start your child's fun and engaging math journey.

What is an Abacus?

The abacus is a traditional tool with a frame made of rods holding a series of beads that can move back and forth. It serves as a physical representation of numbers and arithmetic operations, offering a much better alternative to children using their fingers to count. The abacus provides a visual and tangible way to make abstract mathematical concepts easier to grasp. This visual assistance incorporates mental practice, allowing your child to visualize the beads in their mind and perform arithmetic more quickly and accurately. The abacus also helps children understand patterns and relationships between numbers more effectively. It is highly effective in helping kids build a deep and intuitive understanding of numbers and arithmetic. To assist you, I will provide a timeline of age-appropriate stages to teach your child the abacus so it better sticks.

• Ages 4-5: Introduction of basic concepts. Children learn to identify numbers on the abacus and perform basic arithmetic (addition/subtraction).
• Ages 6-7: Children begin learning more complex arithmetic, including multiplication and division. They can get ahead because the typical school curriculum doesn't start with advanced arithmetic at this point. This is also when mental calculations begin to improve.

How to Use an Abacus for Counting

When you want to use an abacus for counting, it's important to know all the parts and why they are there. In the photo below, you can see rods, beads, a middle beam, and a black dot. Each part has value; the rod with the black dot is the one's place. That said, anything after it to the left is tens, hundreds, thousands, etc. 

Let's look at an example: If we were to look at the one's place(black dot) rod, you would notice 4 beads on the bottom and one bead on the top.

If we want to count 3 beads, we would put 3 beads up as so: 

Here is a link that further explains how to count on the abacus 1-4: https://youtu.be/dvvNwKj5lWE 

If you would like to put 5 beads, you would put down the top bead: 

So if we wanted 9 beads, we would put down our top bead, which represents 5, and put up 4 beads to represent 4 as so: 

This then carries over to our tens, hundreds, and thousands of places. Where the bottom beads represent 1,2,3,4 or 10, 20, 30, 40, etc., or 6,7,8,9, and 60, 70, 80, 9,0, etc, and the top beads represent 5 or 50, 500, etc. 

Here is a link that further explains how to count on the abacus from 5-9: https://youtu.be/nfRIhV_D69I 

In the picture below, we see the top bead put down on the tens place rod, which represents 50 instead of 5. 

Last example, if we wanted to represent 72 on the abacus, what do you think we would do? 

We would put down our 50 and add 20 more, which is two beads on the tens place rod. Then add 2 on our one's place rod. 

How to Use an Abacus for Addition and Subtraction

Here is a link that further explains how to add and subtract on the abacus: https://youtu.be/L93aU7xpOTM 

Let's start by adding 5 plus 4. We do this by putting down the 5 beads and putting up 4 more beads. 

Let's say we want to have 8 beads and take away 4 beads. What do you think we could do? 

Well, 8 beads would look like this: a 5 bead plus 3 more beads. 

We would get rid of our 5 bead and put them up.

 Then we add 1 bead on the bottom like this. 

How to Use an Abacus for Multiplication

This process is actually very easy as long as you know your basic times tables. Our example problem will be 23X4.  

First, you're going to multiply 3x4 in your head to get 12. So, on our abacus, we're going to add a 10 on our tens rod and 2 on our ones rod. 

Next, we're going to move over from the one's rod to the tens rod and multiple 2x4, which gives us 8. Each time we multiply, we MUST remember to move over one rod. 

Here is us adding 5 and we still need to add 3 more beads to get to 8. 

Here is our answer after we finished adding our 8 beads: 

Our final answer is 92, and if you look, you can see in our tens rod 9 beads and in our ones rod two beads. That's it for multiplication on the abacus! The same rules apply to bigger numbers. 

Strategies for Teaching with an Abacus

1. Use Real-Life Examples

Integrating the abacus into everyday life reinforces arithmetic practice, problem-solving, and logical thinking. Help your child make connections by using the abacus in everyday situations, such as counting money, measuring ingredients, and managing or telling time. These are great ways to implement abacus teachings in daily life.

2. Introduce Abacus Concepts Gradually

Start with the basics of understanding the abacus and what each bead represents numerically. Gradually add basic arithmetic, and once the one's place makes sense, continue to introduce more complex arithmetic. Below are age-appropriate timelines for each stage of abacus learning to assist you in your teaching journey:

• Ages 4-5: Introduce abacus identification and basic addition and subtraction up to 10. This helps your child develop a sense of combining and removing quantities.
• Ages 5-6: Introduce multiplication on the abacus as repeated addition. Reinforce skills your child already knows to multiply and learn to multiply larger numbers sooner in their academic career.
• Ages 6-7: Teach division, and your child will be more advanced in addition, subtraction, and multiplication practices. At this point, you can see your child performing very complex arithmetic and improving their mental calculations.

3. Engage in Fun Activities

Keep the abacus learning process fun and engaging by creating activities such as abacus tournaments with teams or timed abacus competitions with your child. The abacus itself is like a game with moving beads, and solving problems is similar to working on a physical puzzle.

• Abacus Tournament: Create two teams where everyone solves different problems. The first team to solve all their problems correctly wins. This fosters friendly competition and teamwork while applying their skills.
• Timed Abacus Challenge: Have your child solve a set of problems within a specific amount of time.
• Abacus Simon Says: Incorporate both arithmetic and listening skills. You act as Simon, listing different problems to solve ensuring your child stays attentive.

4. Interactive Games to Reinforce Learning

There are various games to reinforce abacus learning, including sorting and matching abacus games and online activities.

• Abacus Number Sorting: Use a set of cards (e.g., 1-20), shuffle them, display a card, and have your child show the number on the abacus. After all displayed cards are correctly shown, have your child arrange the numbers in ascending order.
• Abacus Memory Matching: Create pairs of cards where one has a number and the other has an abacus bead representation. Shuffle the cards and lay them face down in a grid format. Your child picks up two at a time to match the number with its abacus representation, strengthening memory and bead-number association.
