Count by 279
Here we will show you how to count by 279, discuss counting by 279 patterns, and tell you why knowing how to count by 279 matters. To start off, note that Count by 279 means counting in 279s, or count by two hundred seventy-nines, and it is also called skip counting by 279.
How to count by 279
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 279, we count 279, 558, 837, 1116, and so on.
In other words, to count in intervals of 279 or skip counting by 279, we start with 279 and then add 279 to get the next number, and then continue adding 279 to the previous number to keep counting by 279, like this:
279
279 + 279 = 558
558 + 279 = 837
837 + 279 = 1116
1116 + 279 = 1395
...
You can of course skip count by 279 forever, so it is impossible to make a list of all numbers, but below is a Count by 279 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 279, the second column has the next ten numbers you get when you skip count by 279, and so forth.
Count by 279 Patterns
We organized the Skip Counting by 279s 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 279, but don't have the Counting by 279s Chart above. Obviously, one pattern with counting by 279s is that the number increases by 279.
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 279 goes 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 and 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 and so on for as long as you count by 279.
Why Count by 279?
We think that understanding and learning about skip counting by 279 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 seventy-nine, you are also creating a list of multiples of 279 that you can use in math when you need the least common multiple. 279 times n equals the nth multiple or skip count of 279.
When you skip count by 279, you are also creating a list of numbers that 279 is divisible by. On top of that, skip counting by 279 is the same as making the 279 times table.
