Count by 17 (Skip Counting by 17s)

Count by 17

Here we will show you how to count by 17, discuss counting by 17 patterns, and tell you why knowing how to count by 17 matters. To start off, note that Count by 17 means counting in 17s, or count by seventeens, and it is also called skip counting by 17.

How to count by 17
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 17, we count 17, 34, 51, 68, and so on.

In other words, to count in intervals of 17 or skip counting by 17, we start with 17 and then add 17 to get the next number, and then continue adding 17 to the previous number to keep counting by 17, like this:

17
17 + 17 = 34
34 + 17 = 51
51 + 17 = 68
68 + 17 = 85
...

You can of course skip count by 17 forever, so it is impossible to make a list of all numbers, but below is a Count by 17 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 17, the second column has the next ten numbers you get when you skip count by 17, and so forth.

Count by 17 Patterns
We organized the Skip Counting by 17s 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 17, but don't have the Counting by 17s Chart above. Obviously, one pattern with counting by 17s is that the number increases by 17.

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 17 goes 7, 4, 1, 8, 5, 2, 9, 6, 3, 0 and 7, 4, 1, 8, 5, 2, 9, 6, 3, 0 and so on for as long as you count by 17.

Why Count by 17?
We think that understanding and learning about skip counting by 17 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by seventeen, you are also creating a list of multiples of 17 that you can use in math when you need the least common multiple. 17 times n equals the nth multiple or skip count of 17.

When you skip count by 17, you are also creating a list of numbers that 17 is divisible by. On top of that, skip counting by 17 is the same as making the 17 times table.
