Count by 225 (Skip Counting by 225s)

Count by 225

Here we will show you how to count by 225, discuss counting by 225 patterns, and tell you why knowing how to count by 225 matters. To start off, note that Count by 225 means counting in 225s, or count by two hundred twenty-fives, and it is also called skip counting by 225.

How to count by 225
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 225, we count 225, 450, 675, 900, and so on.

In other words, to count in intervals of 225 or skip counting by 225, we start with 225 and then add 225 to get the next number, and then continue adding 225 to the previous number to keep counting by 225, like this:

225
225 + 225 = 450
450 + 225 = 675
675 + 225 = 900
900 + 225 = 1125
...

You can of course skip count by 225 forever, so it is impossible to make a list of all numbers, but below is a Count by 225 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 225, the second column has the next ten numbers you get when you skip count by 225, and so forth.

Count by 225 Patterns
We organized the Skip Counting by 225s 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 225, but don't have the Counting by 225s Chart above. Obviously, one pattern with counting by 225s is that the number increases by 225.

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 225 goes 5, 0 and 5, 0 and so on for as long as you count by 225.

Why Count by 225?
We think that understanding and learning about skip counting by 225 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 twenty-five, you are also creating a list of multiples of 225 that you can use in math when you need the least common multiple. 225 times n equals the nth multiple or skip count of 225.

When you skip count by 225, you are also creating a list of numbers that 225 is divisible by. On top of that, skip counting by 225 is the same as making the 225 times table.
