Count by 320 (Skip Counting by 320s)

Count by 320

Here we will show you how to count by 320, discuss counting by 320 patterns, and tell you why knowing how to count by 320 matters. To start off, note that Count by 320 means counting in 320s, or count by three hundred twenties, and it is also called skip counting by 320.

How to count by 320
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 320, we count 320, 640, 960, 1280, and so on.

In other words, to count in intervals of 320 or skip counting by 320, we start with 320 and then add 320 to get the next number, and then continue adding 320 to the previous number to keep counting by 320, like this:

320
320 + 320 = 640
640 + 320 = 960
960 + 320 = 1280
1280 + 320 = 1600
...

You can of course skip count by 320 forever, so it is impossible to make a list of all numbers, but below is a Count by 320 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 320, the second column has the next ten numbers you get when you skip count by 320, and so forth.

Count by 320 Patterns
We organized the Skip Counting by 320s 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 320, but don't have the Counting by 320s Chart above. Obviously, one pattern with counting by 320s is that the number increases by 320.

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 320 goes 0 and 0 and so on for as long as you count by 320.

Why Count by 320?
We think that understanding and learning about skip counting by 320 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by three hundred twenty, you are also creating a list of multiples of 320 that you can use in math when you need the least common multiple. 320 times n equals the nth multiple or skip count of 320.

When you skip count by 320, you are also creating a list of numbers that 320 is divisible by. On top of that, skip counting by 320 is the same as making the 320 times table.
