Count by 387 (Skip Counting by 387s)

Count by 387

Here we will show you how to count by 387, discuss counting by 387 patterns, and tell you why knowing how to count by 387 matters. To start off, note that Count by 387 means counting in 387s, or count by three hundred eighty-sevens, and it is also called skip counting by 387.

How to count by 387
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 387, we count 387, 774, 1161, 1548, and so on.

In other words, to count in intervals of 387 or skip counting by 387, we start with 387 and then add 387 to get the next number, and then continue adding 387 to the previous number to keep counting by 387, like this:

387
387 + 387 = 774
774 + 387 = 1161
1161 + 387 = 1548
1548 + 387 = 1935
...

You can of course skip count by 387 forever, so it is impossible to make a list of all numbers, but below is a Count by 387 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 387, the second column has the next ten numbers you get when you skip count by 387, and so forth.

Count by 387 Patterns
We organized the Skip Counting by 387s 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 387, but don't have the Counting by 387s Chart above. Obviously, one pattern with counting by 387s is that the number increases by 387.

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 387 goes 7, 4, 1, 8, 5, 2, 9, 6, 3, 0 and 7, 4, 1, 8, 5, 2, 9, 6, 3, 0 and so on for as long as you count by 387.

Why Count by 387?
We think that understanding and learning about skip counting by 387 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by three hundred eighty-seven, you are also creating a list of multiples of 387 that you can use in math when you need the least common multiple. 387 times n equals the nth multiple or skip count of 387.

When you skip count by 387, you are also creating a list of numbers that 387 is divisible by. On top of that, skip counting by 387 is the same as making the 387 times table.
