Count by 102 (Skip Counting by 102s)

Count by 102

Here we will show you how to count by 102, discuss counting by 102 patterns, and tell you why knowing how to count by 102 matters. To start off, note that Count by 102 means counting in 102s, or count by one hundred twos, and it is also called skip counting by 102.

How to count by 102
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 102, we count 102, 204, 306, 408, and so on.

In other words, to count in intervals of 102 or skip counting by 102, we start with 102 and then add 102 to get the next number, and then continue adding 102 to the previous number to keep counting by 102, like this:

102
102 + 102 = 204
204 + 102 = 306
306 + 102 = 408
408 + 102 = 510
...

You can of course skip count by 102 forever, so it is impossible to make a list of all numbers, but below is a Count by 102 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 102, the second column has the next ten numbers you get when you skip count by 102, and so forth.

Count by 102 Patterns
We organized the Skip Counting by 102s 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 102, but don't have the Counting by 102s Chart above. Obviously, one pattern with counting by 102s is that the number increases by 102.

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 102 goes 2, 4, 6, 8, 0 and 2, 4, 6, 8, 0 and so on for as long as you count by 102.

Why Count by 102?
We think that understanding and learning about skip counting by 102 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by one hundred two, you are also creating a list of multiples of 102 that you can use in math when you need the least common multiple. 102 times n equals the nth multiple or skip count of 102.

When you skip count by 102, you are also creating a list of numbers that 102 is divisible by. On top of that, skip counting by 102 is the same as making the 102 times table.
