Count by 51 (Skip Counting by 51s)

Count by 51

Here we will show you how to count by 51, discuss counting by 51 patterns, and tell you why knowing how to count by 51 matters. To start off, note that Count by 51 means counting in 51s, or count by fifty-ones, and it is also called skip counting by 51.

How to count by 51
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 51, we count 51, 102, 153, 204, and so on.

In other words, to count in intervals of 51 or skip counting by 51, we start with 51 and then add 51 to get the next number, and then continue adding 51 to the previous number to keep counting by 51, like this:

51
51 + 51 = 102
102 + 51 = 153
153 + 51 = 204
204 + 51 = 255
...

You can of course skip count by 51 forever, so it is impossible to make a list of all numbers, but below is a Count by 51 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 51, the second column has the next ten numbers you get when you skip count by 51, and so forth.

Count by 51 Patterns
We organized the Skip Counting by 51s 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 51, but don't have the Counting by 51s Chart above. Obviously, one pattern with counting by 51s is that the number increases by 51.

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 51 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 51.

Why Count by 51?
We think that understanding and learning about skip counting by 51 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by fifty-one, you are also creating a list of multiples of 51 that you can use in math when you need the least common multiple. 51 times n equals the nth multiple or skip count of 51.

When you skip count by 51, you are also creating a list of numbers that 51 is divisible by. On top of that, skip counting by 51 is the same as making the 51 times table.
