Count by 901 (Skip Counting by 901s)

Count by 901

Here we will show you how to count by 901, discuss counting by 901 patterns, and tell you why knowing how to count by 901 matters. To start off, note that Count by 901 means counting in 901s, or count by nine hundred ones, and it is also called skip counting by 901.

How to count by 901
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 901, we count 901, 1802, 2703, 3604, and so on.

In other words, to count in intervals of 901 or skip counting by 901, we start with 901 and then add 901 to get the next number, and then continue adding 901 to the previous number to keep counting by 901, like this:

901
901 + 901 = 1802
1802 + 901 = 2703
2703 + 901 = 3604
3604 + 901 = 4505
...

You can of course skip count by 901 forever, so it is impossible to make a list of all numbers, but below is a Count by 901 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 901, the second column has the next ten numbers you get when you skip count by 901, and so forth.

Count by 901 Patterns
We organized the Skip Counting by 901s 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 901, but don't have the Counting by 901s Chart above. Obviously, one pattern with counting by 901s is that the number increases by 901.

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 901 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 901.

Why Count by 901?
We think that understanding and learning about skip counting by 901 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by nine hundred one, you are also creating a list of multiples of 901 that you can use in math when you need the least common multiple. 901 times n equals the nth multiple or skip count of 901.

When you skip count by 901, you are also creating a list of numbers that 901 is divisible by. On top of that, skip counting by 901 is the same as making the 901 times table.
