Subtraction Using Pictures


Subtraction is one of the basic operations in math. It is used to find the difference between two numbers or to subtract a number from another number. In the context of basic math, and especially for young learners in grade 1, understanding subtraction can be made easier and more fun through the use of pictures. By visualizing subtraction, students can understand the concepts more clearly and understand the relationship between numbers.

What is subtraction?

Subtraction is an arithmetic operation that represents the operation of removing items from a collection. The result of subtraction is called the difference. For example, if we have 5 apples and we remove 2 apples, we are left with 3 apples. In mathematical terms, we can write this operation as:

5 - 2 = 3

Concept of subtraction using pictures

Visual teaching is one of the most effective ways to help children understand and process information. By using pictures to depict subtraction problems, children can visualize what it means to “remove” or “subtract” objects. This method uses simple drawings or illustrations to represent numbers and demonstrate how subtraction works.

Example 1: Subtracting apples

Suppose we have 5 apples and we want to subtract 2 apples from them.

Now, count the uncut apples:

We can see that we have 3 apples left. So, the subtraction looks like this:

5 - 2 = 3

Example 2: Balloon subtraction

Suppose you have 7 balloons and 4 of them fly away.

If 4 balloons float away:

The subtraction is as follows:

7 - 4 = 3

Example 3: Subtracting flowers

If you have 6 flowers and you give 2 of them to your friend.

After giving two flowers:

The subtraction is as follows:

6 - 2 = 4

Understanding the method

The subtraction with pictures method involves using visual aids to help children understand the concept of removing or taking away. By sketching scenarios or using simple pictures, children can physically see the action of subtraction and count the amount left.

Understanding the problem visually

Consider another example:

If you have 10 cookies and you eat 2, how many are left?

When eating 2 cookies, we perform the following subtraction:

10 - 2 = 8

Learning to subtract in everyday activities

Subtraction using pictures is not just limited to classroom exercises. It can be integrated into daily life to make the learning experience continuous and practical. For example, while gardening, you can use flowers or plants for subtraction practice. In the kitchen, fruits can be used to demonstrate the removal of objects.

Conclusion

Doing subtraction using pictures is a valuable way to introduce young learners to basic arithmetic. Visualization helps promote a better understanding of mathematical operations, leading to strong foundational skills in mathematics. Through everyday experiences and classroom practices, children can enhance their ability to do subtraction and develop a love for learning mathematics in engaging, interactive ways.
