Skip Counting by 3 || Number Learning – Grade 1 Math

In skip counting by 3’s we basically count numbers by skipping number 3 each time we move forward.

Below is the illustration which shows how we will move forward in the number line if we skip counting by three’s

To understand the above illustration, kindly follow the below steps:

Step A:

Step B:
Move forward & skip the number by 3
⟹ 0 + 3 = 3
Now we are at number 3 on number line

Step C:
Again Move Forward by skipping number by 3 from current position
⟹ 3 + 3 = 6
We are standing at number 6 on number line

Step D:
Repeat Step C again and again
⟹ 6 + 3 = 9
⟹ 9 + 3 = 12
⟹ 12 + 3 = 15

The process continues repeatedly and we will get following numbers
0, 3, 6, 9, 12, 15, 18, 21 . . . . .

I hope you have understood the basic idea of skip counting by 3’s using number line.
For you conceptual understanding, let us understand this topic with the help of chart diagram

Above is the chart of numbers from 1 to 100.
When you start from 0 and skip counting by 3, you will get numbers which are circled by red color

Now you have understood the basic concept of counting, it is now time to practice some questions to internalize the theory in our memory.
