IndianTechnoEra: What Is Addition?

What Is Addition?

Addition is a way of finding how many things there are when two or more groups are put together.

We use addition when we combine quantities. For example, if you have 2 pencils and receive 3 more pencils, you can add the two groups to find the total number of pencils.

Learning Objectives

• Understand what addition means.
• Understand addition as putting groups together.
• Recognise the plus sign.
• Write simple addition sentences.
• Understand the meaning of the answer in an addition problem.

What Does Addition Mean?

Addition means putting quantities together to find the total.

● ●    +    ● ● ●

2 + 3 = 5

There are 2 objects in the first group and 3 objects in the second group. When we put them together, there are 5 objects.

The Plus Sign

We use the plus sign (+) to show that we are adding numbers.

+

For example:

2 + 3 = 5

Parts of an Addition Sentence

An addition sentence contains numbers and symbols that tell us what to add and what the total is.

3 + 4 = 7

3 and 4 are the numbers being added.
+ tells us to add.
= tells us that both sides have the same value.
7 is the total.

Putting Two Groups Together

Imagine that there are 3 apples in one group and 2 apples in another group.

🍎 🍎 🍎    +    🍎 🍎

3 + 2 = 5

When the two groups are combined, there are 5 apples altogether.

Counting After Combining

One way to understand addition is to put the groups together and count all the objects.

● ● ● ● ● ●

4 + 2 = 6

Four objects and two more objects make six objects altogether.

Addition Can Make a Bigger Quantity

When we add a positive number to another number, the total tells us how many objects or things there are after combining the groups.

5 + 2 = 7

We started with 5 and added 2 more, giving a total of 7.

Examples

1 + 2 = 3

2 + 4 = 6

5 + 3 = 8

Common Mistakes

• Forgetting that the plus sign means add.
• Counting only one group instead of both groups.
• Writing the wrong total after combining the groups.
• Confusing the plus sign with another mathematical symbol.

Practice

1. What does addition mean?

2. What sign is used for addition?

3. Complete: 2 + 3 = ___.

4. Complete: 4 + 1 = ___.

5. What is the total of 3 and 3?

Try It Yourself

Take two small groups of objects. Count each group, put them together and count the total.

First group + Second group = Total

Quick Revision

• Addition means putting quantities together.
• The plus sign is +.
• The result of addition is the total or sum.
• Objects can help us understand addition.
• 3 + 2 = 5 means 3 and 2 together make 5.

What Comes Next?

Now that you understand what addition means, you will use real objects to practise putting groups together and finding totals.
