Count by 215 (Skip Counting by 215s)

Count by 215

Here we will show you how to count by 215, discuss counting by 215 patterns, and tell you why knowing how to count by 215 matters. To start off, note that Count by 215 means counting in 215s, or count by two hundred fifteens, and it is also called skip counting by 215.

How to count by 215
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 215, we count 215, 430, 645, 860, and so on.

In other words, to count in intervals of 215 or skip counting by 215, we start with 215 and then add 215 to get the next number, and then continue adding 215 to the previous number to keep counting by 215, like this:

215
215 + 215 = 430
430 + 215 = 645
645 + 215 = 860
860 + 215 = 1075
...

You can of course skip count by 215 forever, so it is impossible to make a list of all numbers, but below is a Count by 215 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 215, the second column has the next ten numbers you get when you skip count by 215, and so forth.

Count by 215 Patterns
We organized the Skip Counting by 215s 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 215, but don't have the Counting by 215s Chart above. Obviously, one pattern with counting by 215s is that the number increases by 215.

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 2 over and over. The pattern of the last digit when you count by 215 goes 5, 0 and 5, 0 and so on for as long as you count by 215.

Why Count by 215?
We think that understanding and learning about skip counting by 215 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 hundred fifteen, you are also creating a list of multiples of 215 that you can use in math when you need the least common multiple. 215 times n equals the nth multiple or skip count of 215.

When you skip count by 215, you are also creating a list of numbers that 215 is divisible by. On top of that, skip counting by 215 is the same as making the 215 times table.
