Count by 55 (Skip Counting by 55s)

Count by 55

Here we will show you how to count by 55, discuss counting by 55 patterns, and tell you why knowing how to count by 55 matters. To start off, note that Count by 55 means counting in 55s, or count by fifty-fives, and it is also called skip counting by 55.

How to count by 55
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 55, we count 55, 110, 165, 220, and so on.

In other words, to count in intervals of 55 or skip counting by 55, we start with 55 and then add 55 to get the next number, and then continue adding 55 to the previous number to keep counting by 55, like this:

55
55 + 55 = 110
110 + 55 = 165
165 + 55 = 220
220 + 55 = 275
...

You can of course skip count by 55 forever, so it is impossible to make a list of all numbers, but below is a Count by 55 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 55, the second column has the next ten numbers you get when you skip count by 55, and so forth.

Count by 55 Patterns
We organized the Skip Counting by 55s 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 55, but don't have the Counting by 55s Chart above. Obviously, one pattern with counting by 55s is that the number increases by 55.

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 2 over and over. The pattern of the last digit when you count by 55 goes 5, 0 and 5, 0 and so on for as long as you count by 55.

Why Count by 55?
We think that understanding and learning about skip counting by 55 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-five, you are also creating a list of multiples of 55 that you can use in math when you need the least common multiple. 55 times n equals the nth multiple or skip count of 55.

When you skip count by 55, you are also creating a list of numbers that 55 is divisible by. On top of that, skip counting by 55 is the same as making the 55 times table.
