Count by 303 (Skip Counting by 303s)

Count by 303

Here we will show you how to count by 303, discuss counting by 303 patterns, and tell you why knowing how to count by 303 matters. To start off, note that Count by 303 means counting in 303s, or count by three hundred threes, and it is also called skip counting by 303.

How to count by 303
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 303, we count 303, 606, 909, 1212, and so on.

In other words, to count in intervals of 303 or skip counting by 303, we start with 303 and then add 303 to get the next number, and then continue adding 303 to the previous number to keep counting by 303, like this:

303
303 + 303 = 606
606 + 303 = 909
909 + 303 = 1212
1212 + 303 = 1515
...

You can of course skip count by 303 forever, so it is impossible to make a list of all numbers, but below is a Count by 303 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 303, the second column has the next ten numbers you get when you skip count by 303, and so forth.

Count by 303 Patterns
We organized the Skip Counting by 303s 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 303, but don't have the Counting by 303s Chart above. Obviously, one pattern with counting by 303s is that the number increases by 303.

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 303 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 303.

Why Count by 303?
We think that understanding and learning about skip counting by 303 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by three hundred three, you are also creating a list of multiples of 303 that you can use in math when you need the least common multiple. 303 times n equals the nth multiple or skip count of 303.

When you skip count by 303, you are also creating a list of numbers that 303 is divisible by. On top of that, skip counting by 303 is the same as making the 303 times table.
