Count by 1211

Here we will show you how to count by 1211, discuss counting by 1211 patterns, and tell you why knowing how to count by 1211 matters. To start off, note that Count by 1211 means counting in 1211s, or count by one thousand two hundred elevens, and it is also called skip counting by 1211.

How to count by 1211
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 1211, we count 1211, 2422, 3633, 4844, and so on.

In other words, to count in intervals of 1211 or skip counting by 1211, we start with 1211 and then add 1211 to get the next number, and then continue adding 1211 to the previous number to keep counting by 1211, like this:

1211
1211 + 1211 = 2422
2422 + 1211 = 3633
3633 + 1211 = 4844
4844 + 1211 = 6055
...

You can of course skip count by 1211 forever, so it is impossible to make a list of all numbers, but below is a Count by 1211 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 1211, the second column has the next ten numbers you get when you skip count by 1211, and so forth.

Count by 1211 Patterns
We organized the Skip Counting by 1211s 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 1211, but don't have the Counting by 1211s Chart above. Obviously, one pattern with counting by 1211s is that the number increases by 1211.

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 1211 goes 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 and 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 and so on for as long as you count by 1211.
