Count by 1230 (Skip Counting by 1230s)

Count by 1230

Here we will show you how to count by 1230, discuss counting by 1230 patterns, and tell you why knowing how to count by 1230 matters. To start off, note that Count by 1230 means counting in 1230s, or count by one thousand two hundred thirties, and it is also called skip counting by 1230.

How to count by 1230
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 1230, we count 1230, 2460, 3690, 4920, and so on.

In other words, to count in intervals of 1230 or skip counting by 1230, we start with 1230 and then add 1230 to get the next number, and then continue adding 1230 to the previous number to keep counting by 1230, like this:

1230
1230 + 1230 = 2460
2460 + 1230 = 3690
3690 + 1230 = 4920
4920 + 1230 = 6150
...

You can of course skip count by 1230 forever, so it is impossible to make a list of all numbers, but below is a Count by 1230 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 1230, the second column has the next ten numbers you get when you skip count by 1230, and so forth.

Count by 1230 Patterns
We organized the Skip Counting by 1230s 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 1230, but don't have the Counting by 1230s Chart above. Obviously, one pattern with counting by 1230s is that the number increases by 1230.

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 1230 goes 0 and 0 and so on for as long as you count by 1230.

Why Count by 1230?
