Count by 1901 (Skip Counting by 1901s)

Count by 1901

Here we will show you how to count by 1901, discuss counting by 1901 patterns, and tell you why knowing how to count by 1901 matters. To start off, note that Count by 1901 means counting in 1901s, or count by one thousand nine hundred ones, and it is also called skip counting by 1901.

How to count by 1901
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 1901, we count 1901, 3802, 5703, 7604, and so on.

In other words, to count in intervals of 1901 or skip counting by 1901, we start with 1901 and then add 1901 to get the next number, and then continue adding 1901 to the previous number to keep counting by 1901, like this:

1901
1901 + 1901 = 3802
3802 + 1901 = 5703
5703 + 1901 = 7604
7604 + 1901 = 9505
...

You can of course skip count by 1901 forever, so it is impossible to make a list of all numbers, but below is a Count by 1901 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 1901, the second column has the next ten numbers you get when you skip count by 1901, and so forth.

Count by 1901 Patterns
We organized the Skip Counting by 1901s 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 1901, but don't have the Counting by 1901s Chart above. Obviously, one pattern with counting by 1901s is that the number increases by 1901.

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 1901 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 1901.

Why Count by 1901?
We think that understanding and learning about skip counting by 1901 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by one thousand nine hundred one, you are also creating a list of multiples of 1901 that you can use in math when you need the least common multiple. 1901 times n equals the nth multiple or skip count of 1901.

When you skip count by 1901, you are also creating a list of numbers that 1901 is divisible by. On top of that, skip counting by 1901 is the same as making the 1901 times table.
