Count by 345 (Skip Counting by 345s)

Count by 345

Here we will show you how to count by 345, discuss counting by 345 patterns, and tell you why knowing how to count by 345 matters. To start off, note that Count by 345 means counting in 345s, or count by three hundred forty-fives, and it is also called skip counting by 345.

How to count by 345
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 345, we count 345, 690, 1035, 1380, and so on.

In other words, to count in intervals of 345 or skip counting by 345, we start with 345 and then add 345 to get the next number, and then continue adding 345 to the previous number to keep counting by 345, like this:

345
345 + 345 = 690
690 + 345 = 1035
1035 + 345 = 1380
1380 + 345 = 1725
...

You can of course skip count by 345 forever, so it is impossible to make a list of all numbers, but below is a Count by 345 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 345, the second column has the next ten numbers you get when you skip count by 345, and so forth.

Count by 345 Patterns
We organized the Skip Counting by 345s 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 345, but don't have the Counting by 345s Chart above. Obviously, one pattern with counting by 345s is that the number increases by 345.

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 345 goes 5, 0 and 5, 0 and so on for as long as you count by 345.

Why Count by 345?
We think that understanding and learning about skip counting by 345 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 forty-five, you are also creating a list of multiples of 345 that you can use in math when you need the least common multiple. 345 times n equals the nth multiple or skip count of 345.
