Count by 2001 (Skip Counting by 2001s)

Count by 2001

Here we will show you how to count by 2001, discuss counting by 2001 patterns, and tell you why knowing how to count by 2001 matters. To start off, note that Count by 2001 means counting in 2001s, or count by two thousand ones, and it is also called skip counting by 2001.

How to count by 2001
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 2001, we count 2001, 4002, 6003, 8004, and so on.

In other words, to count in intervals of 2001 or skip counting by 2001, we start with 2001 and then add 2001 to get the next number, and then continue adding 2001 to the previous number to keep counting by 2001, like this:

2001
2001 + 2001 = 4002
4002 + 2001 = 6003
6003 + 2001 = 8004
8004 + 2001 = 10005
...

You can of course skip count by 2001 forever, so it is impossible to make a list of all numbers, but below is a Count by 2001 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 2001, the second column has the next ten numbers you get when you skip count by 2001, and so forth.

Count by 2001 Patterns
We organized the Skip Counting by 2001s 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 2001, but don't have the Counting by 2001s Chart above. Obviously, one pattern with counting by 2001s is that the number increases by 2001.

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 2001 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 2001.

Why Count by 2001?
We think that understanding and learning about skip counting by 2001 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by two thousand one, you are also creating a list of multiples of 2001 that you can use in math when you need the least common multiple. 2001 times n equals the nth multiple or skip count of 2001.

When you skip count by 2001, you are also creating a list of numbers that 2001 is divisible by. On top of that, skip counting by 2001 is the same as making the 2001 times table.
