Count by 805 (Skip Counting by 805s)

Count by 805

Here we will show you how to count by 805, discuss counting by 805 patterns, and tell you why knowing how to count by 805 matters. To start off, note that Count by 805 means counting in 805s, or count by eight hundred fives, and it is also called skip counting by 805.

How to count by 805
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 805, we count 805, 1610, 2415, 3220, and so on.

In other words, to count in intervals of 805 or skip counting by 805, we start with 805 and then add 805 to get the next number, and then continue adding 805 to the previous number to keep counting by 805, like this:

805
805 + 805 = 1610
1610 + 805 = 2415
2415 + 805 = 3220
3220 + 805 = 4025
...

You can of course skip count by 805 forever, so it is impossible to make a list of all numbers, but below is a Count by 805 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 805, the second column has the next ten numbers you get when you skip count by 805, and so forth.

Count by 805 Patterns
We organized the Skip Counting by 805s 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 805, but don't have the Counting by 805s Chart above. Obviously, one pattern with counting by 805s is that the number increases by 805.

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 2 over and over. The pattern of the last digit when you count by 805 goes 5, 0 and 5, 0 and so on for as long as you count by 805.

Why Count by 805?
We think that understanding and learning about skip counting by 805 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by eight hundred five, you are also creating a list of multiples of 805 that you can use in math when you need the least common multiple. 805 times n equals the nth multiple or skip count of 805.

When you skip count by 805, you are also creating a list of numbers that 805 is divisible by. On top of that, skip counting by 805 is the same as making the 805 times table.
