Count by 311 (Skip Counting by 311s)

Count by 311

Here we will show you how to count by 311, discuss counting by 311 patterns, and tell you why knowing how to count by 311 matters. To start off, note that Count by 311 means counting in 311s, or count by three hundred elevens, and it is also called skip counting by 311.

How to count by 311
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 311, we count 311, 622, 933, 1244, and so on.

In other words, to count in intervals of 311 or skip counting by 311, we start with 311 and then add 311 to get the next number, and then continue adding 311 to the previous number to keep counting by 311, like this:

311
311 + 311 = 622
622 + 311 = 933
933 + 311 = 1244
1244 + 311 = 1555
...

You can of course skip count by 311 forever, so it is impossible to make a list of all numbers, but below is a Count by 311 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 311, the second column has the next ten numbers you get when you skip count by 311, and so forth.

Count by 311 Patterns
We organized the Skip Counting by 311s 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 311, but don't have the Counting by 311s Chart above. Obviously, one pattern with counting by 311s is that the number increases by 311.

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 311 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 311.

Why Count by 311?
We think that understanding and learning about skip counting by 311 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 eleven, you are also creating a list of multiples of 311 that you can use in math when you need the least common multiple. 311 times n equals the nth multiple or skip count of 311.

When you skip count by 311, you are also creating a list of numbers that 311 is divisible by. On top of that, skip counting by 311 is the same as making the 311 times table.
