Addition for Class 2

In this chapter, the students will learn about class 2 addition. They will learn about the term’s addends, addition sign, and sum.

In this learning concept, the students will learn:

Horizontal Addition
Vertical Addition

Each concept is explained to class 2 maths students using illustrations, examples, misconceptions, and mind maps. You can assess your learning by solving the two printable worksheets at the pages' end.
Download the addition worksheet for class 2 and check the solutions for the concept of addition provided in PDF format.

Addition- To find a total or count the objects together we use addition.

Parts of Addition
- Addends: The numbers we add
- + (Plus): Addition sign
- Sum: Total after doing addition
Example:

We have learned the addition of one-digit numbers. Now we will learn the addition of the two-digits numbers.

Example:

There are 12 matchsticks and we need to add 22 matchsticks to it.

Count the total number of matchsticks.

A bundle of ten matchsticks represents the 1 ten and two individual matchsticks represent 2 ones. It makes number 12.

Similarly, two bundles of ten matchsticks represent the 2 tens and two individual matchsticks represent 2 ones. It makes number 22.

Now, we want to count all these matchsticks together.

Put all the bundles together and individual matchsticks together.

Three bundles of ten matchsticks represent 3 tens and four individual matchsticks represent 4 ones. It makes number 34.

So, the sum of the numbers 12 and 22 is 34:

12 + 22 = 34

Note:

Here we add the numbers at the ones place and the numbers at tens place separately.

While doing addition always start by adding ones place numbers.(From right to left)
Representation of the Addition

Horizontal Addition

Step 1: Write the numbers horizontally connected with plus sign.

Step 2: Add the ones place numbers.

Step 3: Add the tens place numbers.

Example:

Step 1: Write the numbers horizontally.

Step 2: Add the ones place numbers.

Here, the first addend at ones place is the number 4, and the second addend at ones place is 5. Add the 4 and 5.

Step 3: Add the tens place numbers.

Here, the first addend at tens place is 2, and the second addend at tens place is 7. Add 2 and 7.

So, we get
Vertical Addition

(To do vertical addition we use place value tables.)

Step 1: Write the numbers in place value tables correctly.

Step 2: Add the ones place numbers.

Step 3: Addition the tens place numbers.

Example:

Step 1: Write the numbers in place value tables correctly. On the write the representation for the numbers is shown.

Step 2: Add the numbers at ones place.

Step 3: Add the numbers at tens place.

So, we get:

Addition with Carryover

Example:

Step 1: Write the numbers in place value tables correctly.

Step 2: Add the numbers at ones place.

When we add 5 and 7, we get 12. But we can’t write the two-digit number at the ones place.

Step 3: Carry over the tens place number of the sum to the next place that is tens place.

Out of 12 ones, we can make a group of 10 flowers which is 1 ten. So, 2 flowers are remaining which indicates 2 ones.

Step 4: Add the numbers at tens place. (Including the carry over number also)

So, we get
