In this post we will understand addition of different numbers with 3. For conceptual understanding we will take the help of number line and after that we will move on to solve some questions and activities related to it.

When we add number 3 to any number, then we have to make three jumps on number line to get the final number.

Let us consider the following addition
10 + 3

To solve the above addition, understand the following steps

Step 1: Start at number 10
Step 2: Make three jumps to right
Step 3 : Stop at number 13

Hence the answer for addition is : 10 + 3 = 13

Example 02
5 + 3

To solve the above addition, understand the following steps

Step 1: Start at number 5
Step 2: Make three jumps to right
Step 3 : Stop at number 8

Hence the answer for addition is : 5 + 3 = 8

Example 03
7 + 3

To solve the above addition, understand the following steps

Step 1: Start at number 7
Step 2: Make three jumps to right
Step 3 : Stop at number 10

Hence the answer for addition is : 7 + 3 = 10

Now you have got the basic idea about adding number with 3.
Let us now see addition of 3 to numbers up to 20

Conclusion : On adding number with 3, we have to jump three times to the right on number line.
