Count by 408 (Skip Counting by 408s)

Count by 408

Here we will show you how to count by 408, discuss counting by 408 patterns, and tell you why knowing how to count by 408 matters. To start off, note that Count by 408 means counting in 408s, or count by four hundred eights, and it is also called skip counting by 408.

How to count by 408
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 408, we count 408, 816, 1224, 1632, and so on.

In other words, to count in intervals of 408 or skip counting by 408, we start with 408 and then add 408 to get the next number, and then continue adding 408 to the previous number to keep counting by 408, like this:

408
408 + 408 = 816
816 + 408 = 1224
1224 + 408 = 1632
1632 + 408 = 2040
...

You can of course skip count by 408 forever, so it is impossible to make a list of all numbers, but below is a Count by 408 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 408, the second column has the next ten numbers you get when you skip count by 408, and so forth.

Count by 408 Patterns
We organized the Skip Counting by 408s 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 408, but don't have the Counting by 408s Chart above. Obviously, one pattern with counting by 408s is that the number increases by 408.

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 5 over and over. The pattern of the last digit when you count by 408 goes 8, 6, 4, 2, 0 and 8, 6, 4, 2, 0 and so on for as long as you count by 408.

Why Count by 408?
We think that understanding and learning about skip counting by 408 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by four hundred eight, you are also creating a list of multiples of 408 that you can use in math when you need the least common multiple. 408 times n equals the nth multiple or skip count of 408.

When you skip count by 408, you are also creating a list of numbers that 408 is divisible by. On top of that, skip counting by 408 is the same as making the 408 times table.
