How to Teach Subtraction to Elementary School Students

Teaching subtraction to elementary school students can be a challenging task, but with the right approach and strategies, it can become a fun and engaging learning experience. In this article, we will explore the basics of subtraction, effective teaching strategies, and a step-by-step approach to help students grasp this important mathematical concept.

Understanding the Basics of Subtraction

Introducing the concept of subtraction

Subtraction is like magic! Just as a magician makes things disappear, subtraction helps us take away or find the difference between two numbers. It’s all about understanding how much is left when we remove some objects from a group. Remember, subtraction is the key to unlocking the mysteries of mathematics!

Let’s dive deeper into the fascinating world of subtraction and explore its meaning, the difference between minuend and subtrahend, as well as the concept of regrouping or borrowing.

Explaining the meaning of subtraction

Imagine you have a plate filled with cookies. When you eat some of them, what happens? The number of cookies on the plate decreases. This decrease in quantity is subtraction. It is the process of removing or taking away something from a whole.

Subtraction is a fundamental mathematical operation that helps us compare quantities and understand the relationship between numbers. Whether you’re counting your toys, calculating your allowance, or solving complex mathematical problems, subtraction is an essential tool that allows us to find answers and make sense of the world around us.

Teaching the difference between minuend and subtrahend

Now, let’s talk about the minuend and subtrahend. Think of the minuend as the whole group of objects you have, and the subtrahend as the number of objects you want to take away. For example, if you have 10 cookies (the minuend) and you eat 3 cookies (the subtrahend), the difference is the number of cookies left.

Understanding the minuend and subtrahend is crucial in subtraction because they determine the starting point and the amount we want to remove. By identifying these components, we can accurately perform subtraction and find the solution.

Introducing the concept of regrouping or borrowing

Sometimes, when subtracting two numbers, we may need to borrow or regroup. This is when the subtrahend is larger than the minuend. Imagine you have 5 apples, but you want to subtract 7 apples. Well, we can’t do that directly. To solve this, we need to borrow or regroup from another place value. It’s like asking a friend for some apples to complete the subtraction.

Regrouping or borrowing is a valuable strategy that allows us to subtract larger numbers and overcome the limitations of the minuend. By borrowing from a higher place value, we can ensure that our subtraction is accurate and precise. This concept introduces us to the idea of exchanging or rearranging quantities to make calculations more manageable.

Subtraction is an exciting journey that takes us from simple arithmetic to complex problem-solving. It empowers us to analyze situations, make comparisons, and find solutions. So, let’s continue exploring the wonders of subtraction and unlock the hidden treasures of mathematics!

Strategies for Teaching Subtraction

Subtraction is an essential mathematical skill that students need to master. To ensure effective learning and understanding of subtraction, educators can employ various strategies that engage students and make the concept more relatable and enjoyable.

Using manipulatives and visual aids

As famous pediatrician Maria Montessori once said, “The hands are the instruments of man’s intelligence.” By using manipulatives like counting cubes, blocks, or even everyday objects, students can physically see the subtraction process. This hands-on approach helps them visualize the concept, making it easier to understand and remember.

For instance, teachers can provide students with a set of counting cubes and ask them to subtract a certain number from the total. As students remove the cubes one by one, they can see the quantity decreasing, reinforcing the concept of subtraction.

Furthermore, teachers can introduce visual aids such as number lines or subtraction charts to help students visualize the process of subtracting numbers. These visual representations provide a clear and concrete way for students to grasp the concept.

Incorporating real-life examples and word problems

The renowned obstetrician and philosopher Frederick Leboyer believed that learning should be meaningful and relatable. To make subtraction meaningful, try incorporating real-life examples and word problems into your lessons.

For instance, ask students to calculate how much money they will have left after buying their favorite toys. This real-life scenario not only makes subtraction relevant but also helps students understand the practical application of the concept.

Teachers can also present word problems that involve subtraction in everyday situations. For example, students can solve practical problems involving sharing objects among friends or distributing items equally among a group, thereby reinforcing the concept of subtraction in a relatable context.

Utilizing technology and educational apps

Psychologist and educational theorist Lev Vygotsky emphasized the importance of using tools to enhance learning. In today’s digital age, educational apps and online resources can be powerful tools in teaching subtraction.

There are numerous interactive apps available that provide engaging subtraction games and exercises. These apps allow students to practice subtraction in a fun and interactive manner, making learning enjoyable and effective. Teachers can incorporate these apps into their lessons to supplement traditional teaching methods and provide students with a well-rounded learning experience.

Implementing interactive games and activities

Engagement and fun go hand in hand when it comes to effective learning. Albert Einstein once said, “Play is the highest form of research.” Incorporate interactive games and hands-on activities in your lessons to make subtraction more engaging.

For example, teachers can organize a subtraction scavenger hunt, where students find objects and subtract their quantities. This activity not only reinforces subtraction skills but also encourages critical thinking and problem-solving.

Another fun activity is a subtraction relay race, where students solve subtraction problems to move forward. This game not only promotes healthy competition but also helps students practice subtraction in a dynamic and exciting way.

By incorporating these interactive games and activities, teachers can create a positive and engaging learning environment that encourages active participation and deep understanding of subtraction.

Step-by-Step Approach to Teaching Subtraction

Breaking down subtraction into smaller steps

Renowned psychologist Jean Piaget suggested that complex concepts should be broken down into smaller, more manageable steps. This approach allows students to build a strong foundation and develop a deeper understanding of subtraction. By starting with concrete objects, such as counting blocks or manipulatives, students can physically see the process of taking away and understand the concept of subtraction.

Once students are comfortable with using concrete objects, the transition to abstract representations can begin. Introduce the concept of subtraction using numbers and number sentences. Provide students with examples and encourage them to solve subtraction problems using the numbers provided. This step-by-step approach ensures that students grasp the fundamental principles of subtraction before moving on to more complex problems.

Teaching subtraction through number lines and counting backwards

Cognitive psychologist Lev Vygotsky proposed that students should be guided through the zone of proximal development, where they can learn with the help of a more knowledgeable other. One effective method of teaching subtraction is through the use of number lines. Number lines provide a visual representation of the subtraction process, allowing students to see the relationship between numbers and the concept of taking away.

Start by using whole numbers on the number line, and gradually introduce decimals and negative numbers. Encourage students to count backwards to find the difference, reinforcing the concept of subtraction. This approach helps students develop a deeper understanding of subtraction as they visually see the process of counting backwards and the relationship between numbers on the number line.

Introducing subtraction through fact families

Connecting concepts is key to long-lasting understanding. Introduce subtraction within the context of fact families, where addition and subtraction are inversely related. Fact families help students see the connection between addition and subtraction, reinforcing the concept that subtraction is the inverse operation of addition.

For example, if 5 + 3 = 8, then 8 – 3 = 5. By showing the relationship between addition and subtraction, students can make connections and develop a solid foundation in mathematical operations. This approach not only strengthens their understanding of subtraction but also enhances their overall mathematical fluency.

Practicing subtraction with timed drills and worksheets

To reinforce newly acquired skills, practice and repetition are essential. Famous psychologist B.F. Skinner advocated for the importance of reinforcement in learning. Timed drills and worksheets provide students with opportunities to practice subtraction in a structured and focused manner.

By setting a time limit for completing subtraction problems, students are encouraged to work efficiently and develop their subtraction fluency. These timed drills also help build students’ confidence in tackling more complex problems, as they become more comfortable with the subtraction process.

Worksheets offer a variety of subtraction problems for students to solve independently. This allows them to practice subtraction in different contexts and apply their knowledge to real-life situations. The combination of timed drills and worksheets ensures that students have ample opportunities to practice and reinforce their subtraction skills.


Teaching subtraction to elementary school students may seem daunting, but with the right strategies and creative approaches, it can become an enjoyable and engaging experience. By breaking down the concept, utilizing various teaching methods, and providing ample practice, students can develop a solid understanding of subtraction. Remember to use hands-on activities, real-life examples, and technology to enhance the learning experience. With your guidance and support, young mathematicians will conquer subtraction with ease, opening doors to a world full of numbers and possibilities!
