Count by 98
Here we will show you how to count by 98, discuss counting by 98 patterns, and tell you why knowing how to count by 98 matters. To start off, note that Count by 98 means counting in 98s, or count by ninety-eights, and it is also called skip counting by 98.
How to count by 98
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 98, we count 98, 196, 294, 392, and so on.
In other words, to count in intervals of 98 or skip counting by 98, we start with 98 and then add 98 to get the next number, and then continue adding 98 to the previous number to keep counting by 98, like this:
98
98 + 98 = 196
196 + 98 = 294
294 + 98 = 392
392 + 98 = 490
...
You can of course skip count by 98 forever, so it is impossible to make a list of all numbers, but below is a Count by 98 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 98, the second column has the next ten numbers you get when you skip count by 98, and so forth.
Count by 98 Patterns
We organized the Skip Counting by 98s 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 98, but don't have the Counting by 98s Chart above. Obviously, one pattern with counting by 98s is that the number increases by 98.
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 98 goes 8, 6, 4, 2, 0 and 8, 6, 4, 2, 0 and so on for as long as you count by 98.
Why Count by 98?
We think that understanding and learning about skip counting by 98 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.
When you count by ninety-eight, you are also creating a list of multiples of 98 that you can use in math when you need the least common multiple. 98 times n equals the nth multiple or skip count of 98.
When you skip count by 98, you are also creating a list of numbers that 98 is divisible by. On top of that, skip counting by 98 is the same as making the 98 times table.
