Count by 555 (Skip Counting by 555s)

Count by 555

Here we will show you how to count by 555, discuss counting by 555 patterns, and tell you why knowing how to count by 555 matters. To start off, note that Count by 555 means counting in 555s, or count by five hundred fifty-fives, and it is also called skip counting by 555.

How to count by 555
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 555, we count 555, 1110, 1665, 2220, and so on.

In other words, to count in intervals of 555 or skip counting by 555, we start with 555 and then add 555 to get the next number, and then continue adding 555 to the previous number to keep counting by 555, like this:

555
555 + 555 = 1110
1110 + 555 = 1665
1665 + 555 = 2220
2220 + 555 = 2775
...

You can of course skip count by 555 forever, so it is impossible to make a list of all numbers, but below is a Count by 555 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 555, the second column has the next ten numbers you get when you skip count by 555, and so forth.

Count by 555 Patterns
We organized the Skip Counting by 555s 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 555, but don't have the Counting by 555s Chart above. Obviously, one pattern with counting by 555s is that the number increases by 555.

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 555 goes 5, 0 and 5, 0 and so on for as long as you count by 555.
