Count by 1900 (Skip Counting by 1900s)

Count by 1900

Here we will show you how to count by 1900, discuss counting by 1900 patterns, and tell you why knowing how to count by 1900 matters. To start off, note that Count by 1900 means counting in 1900s, or count by one thousand nine hundreds, and it is also called skip counting by 1900.

How to count by 1900
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 1900, we count 1900, 3800, 5700, 7600, and so on.

In other words, to count in intervals of 1900 or skip counting by 1900, we start with 1900 and then add 1900 to get the next number, and then continue adding 1900 to the previous number to keep counting by 1900, like this:

1900
1900 + 1900 = 3800
3800 + 1900 = 5700
5700 + 1900 = 7600
7600 + 1900 = 9500
...

You can of course skip count by 1900 forever, so it is impossible to make a list of all numbers, but below is a Count by 1900 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 1900, the second column has the next ten numbers you get when you skip count by 1900, and so forth.

Count by 1900 Patterns
We organized the Skip Counting by 1900s 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 1900, but don't have the Counting by 1900s Chart above. Obviously, one pattern with counting by 1900s is that the number increases by 1900.

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 1 over and over. The pattern of the last digit when you count by 1900 goes 0 and 0 and so on for as long as you count by 1900.

Why Count by 1900?
We think that understanding and learning about skip counting by 1900 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, you are also creating a list of multiples of 1900 that you can use in math when you need the least common multiple. 1900 times n equals the nth multiple or skip count of 1900.

When you skip count by 1900, you are also creating a list of numbers that 1900 is divisible by. On top of that, skip counting by 1900 is the same as making the 1900 times table.
