Count by 1003 (Skip Counting by 1003s)

Count by 1003

Here we will show you how to count by 1003, discuss counting by 1003 patterns, and tell you why knowing how to count by 1003 matters. To start off, note that Count by 1003 means counting in 1003s, or count by one thousand threes, and it is also called skip counting by 1003.

How to count by 1003
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 1003, we count 1003, 2006, 3009, 4012, and so on.

In other words, to count in intervals of 1003 or skip counting by 1003, we start with 1003 and then add 1003 to get the next number, and then continue adding 1003 to the previous number to keep counting by 1003, like this:

1003
1003 + 1003 = 2006
2006 + 1003 = 3009
3009 + 1003 = 4012
4012 + 1003 = 5015
...

You can of course skip count by 1003 forever, so it is impossible to make a list of all numbers, but below is a Count by 1003 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 1003, the second column has the next ten numbers you get when you skip count by 1003, and so forth.

Count by 1003 Patterns
We organized the Skip Counting by 1003s 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 1003, but don't have the Counting by 1003s Chart above. Obviously, one pattern with counting by 1003s is that the number increases by 1003.

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 1003 goes 3, 6, 9, 2, 5, 8, 1, 4, 7, 0 and 3, 6, 9, 2, 5, 8, 1, 4, 7, 0 and so on for as long as you count by 1003.

Why Count by 1003?
We think that understanding and learning about skip counting by 1003 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 three, you are also creating a list of multiples of 1003 that you can use in math when you need the least common multiple. 1003 times n equals the nth multiple or skip count of 1003.

When you skip count by 1003, you are also creating a list of numbers that 1003 is divisible by. On top of that, skip counting by 1003 is the same as making the 1003 times table.
