Count by 31 (Skip Counting by 31s)

Count by 31

Here we will show you how to count by 31, discuss counting by 31 patterns, and tell you why knowing how to count by 31 matters. To start off, note that Count by 31 means counting in 31s, or count by thirty-ones, and it is also called skip counting by 31.

How to count by 31
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 31, we count 31, 62, 93, 124, and so on.

In other words, to count in intervals of 31 or skip counting by 31, we start with 31 and then add 31 to get the next number, and then continue adding 31 to the previous number to keep counting by 31, like this:

31
31 + 31 = 62
62 + 31 = 93
93 + 31 = 124
124 + 31 = 155
...

You can of course skip count by 31 forever, so it is impossible to make a list of all numbers, but below is a Count by 31 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 31, the second column has the next ten numbers you get when you skip count by 31, and so forth.

Count by 31 Patterns
We organized the Skip Counting by 31s 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 31, but don't have the Counting by 31s Chart above. Obviously, one pattern with counting by 31s is that the number increases by 31.

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 10 over and over. The pattern of the last digit when you count by 31 goes 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 and 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 and so on for as long as you count by 31.

Why Count by 31?
We think that understanding and learning about skip counting by 31 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by thirty-one, you are also creating a list of multiples of 31 that you can use in math when you need the least common multiple. 31 times n equals the nth multiple or skip count of 31.

When you skip count by 31, you are also creating a list of numbers that 31 is divisible by. On top of that, skip counting by 31 is the same as making the 31 times table.
