Count by 210 (Skip Counting by 210s)

Count by 210

Here we will show you how to count by 210, discuss counting by 210 patterns, and tell you why knowing how to count by 210 matters. To start off, note that Count by 210 means counting in 210s, or count by two hundred tens, and it is also called skip counting by 210.

How to count by 210
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 210, we count 210, 420, 630, 840, and so on.

In other words, to count in intervals of 210 or skip counting by 210, we start with 210 and then add 210 to get the next number, and then continue adding 210 to the previous number to keep counting by 210, like this:

210
210 + 210 = 420
420 + 210 = 630
630 + 210 = 840
840 + 210 = 1050
...

You can of course skip count by 210 forever, so it is impossible to make a list of all numbers, but below is a Count by 210 Chart of the first 100 numbers to get you started.

Looking at the chart above, you will see that the first column has the first ten numbers you get when you skip count by 210, the second column has the next ten numbers you get when you skip count by 210, and so forth.

Count by 210 Patterns
We organized the Skip Counting by 210s Chart above in 10 rows and 10 columns so you can easily identify patterns.

Skip counting always creates patterns. Figuring out these patterns may help you if want to count by 210, but don't have the Counting by 210s Chart above. Obviously, one pattern with counting by 210s is that the number increases by 210.

Furthermore, if you look at each row above, each number in the row has the same last digit (ones place). That means that every tenth number has the same last digit.

If you look down the columns, you will see that the last digit (ones place) repeats itself in blocks of 1 over and over. The pattern of the last digit when you count by 210 goes 0 and 0 and so on for as long as you count by 210.

Why Count by 210?
We think that understanding and learning about skip counting by 210 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by two hundred ten, you are also creating a list of multiples of 210 that you can use in math when you need the least common multiple. 210 times n equals the nth multiple or skip count of 210.

When you skip count by 210, you are also creating a list of numbers that 210 is divisible by. On top of that, skip counting by 210 is the same as making the 210 times table.
