Count by 280 (Skip Counting by 280s)

Count by 280

Here we will show you how to count by 280, discuss counting by 280 patterns, and tell you why knowing how to count by 280 matters. To start off, note that Count by 280 means counting in 280s, or count by two hundred eighties, and it is also called skip counting by 280.

How to count by 280
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 280, we count 280, 560, 840, 1120, and so on.

In other words, to count in intervals of 280 or skip counting by 280, we start with 280 and then add 280 to get the next number, and then continue adding 280 to the previous number to keep counting by 280, like this:

280
280 + 280 = 560
560 + 280 = 840
840 + 280 = 1120
1120 + 280 = 1400
...

You can of course skip count by 280 forever, so it is impossible to make a list of all numbers, but below is a Count by 280 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 280, the second column has the next ten numbers you get when you skip count by 280, and so forth.

Count by 280 Patterns
We organized the Skip Counting by 280s 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 280, but don't have the Counting by 280s Chart above. Obviously, one pattern with counting by 280s is that the number increases by 280.

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 1 over and over. The pattern of the last digit when you count by 280 goes 0 and 0 and so on for as long as you count by 280.

Why Count by 280?
We think that understanding and learning about skip counting by 280 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 eighty, you are also creating a list of multiples of 280 that you can use in math when you need the least common multiple. 280 times n equals the nth multiple or skip count of 280.

When you skip count by 280, you are also creating a list of numbers that 280 is divisible by. On top of that, skip counting by 280 is the same as making the 280 times table.
