Count by 111 (Skip Counting by 111s)

Count by 111

Here we will show you how to count by 111, discuss counting by 111 patterns, and tell you why knowing how to count by 111 matters. To start off, note that Count by 111 means counting in 111s, or count by one hundred elevens, and it is also called skip counting by 111.

How to count by 111
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 111, we count 111, 222, 333, 444, and so on.

In other words, to count in intervals of 111 or skip counting by 111, we start with 111 and then add 111 to get the next number, and then continue adding 111 to the previous number to keep counting by 111, like this:

111
111 + 111 = 222
222 + 111 = 333
333 + 111 = 444
444 + 111 = 555
...

You can of course skip count by 111 forever, so it is impossible to make a list of all numbers, but below is a Count by 111 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 111, the second column has the next ten numbers you get when you skip count by 111, and so forth.

Count by 111 Patterns
We organized the Skip Counting by 111s 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 111, but don't have the Counting by 111s Chart above. Obviously, one pattern with counting by 111s is that the number increases by 111.

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 111 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 111.

Why Count by 111?
We think that understanding and learning about skip counting by 111 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by one hundred eleven, you are also creating a list of multiples of 111 that you can use in math when you need the least common multiple. 111 times n equals the nth multiple or skip count of 111.

When you skip count by 111, you are also creating a list of numbers that 111 is divisible by. On top of that, skip counting by 111 is the same as making the 111 times table.
