Count by 503 (Skip Counting by 503s)

Count by 503

Here we will show you how to count by 503, discuss counting by 503 patterns, and tell you why knowing how to count by 503 matters. To start off, note that Count by 503 means counting in 503s, or count by five hundred threes, and it is also called skip counting by 503.

How to count by 503
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 503, we count 503, 1006, 1509, 2012, and so on.

In other words, to count in intervals of 503 or skip counting by 503, we start with 503 and then add 503 to get the next number, and then continue adding 503 to the previous number to keep counting by 503, like this:

503
503 + 503 = 1006
1006 + 503 = 1509
1509 + 503 = 2012
2012 + 503 = 2515
...

You can of course skip count by 503 forever, so it is impossible to make a list of all numbers, but below is a Count by 503 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 503, the second column has the next ten numbers you get when you skip count by 503, and so forth.

Count by 503 Patterns
We organized the Skip Counting by 503s 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 503, but don't have the Counting by 503s Chart above. Obviously, one pattern with counting by 503s is that the number increases by 503.

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 503 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 503.

Why Count by 503?
We think that understanding and learning about skip counting by 503 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by five hundred three, you are also creating a list of multiples of 503 that you can use in math when you need the least common multiple. 503 times n equals the nth multiple or skip count of 503.

When you skip count by 503, you are also creating a list of numbers that 503 is divisible by. On top of that, skip counting by 503 is the same as making the 503 times table.
