Whether flying high on the trapeze or showing off on the ground, acrobats always amaze.

  • But did you know numbers can do tricks, too?

3 and 5 are very talented acrobats in the number neighborhood! One of their tricks is to divide into other numbers.

3 can split 9 perfectly, and 5 makes dividing 20 look easy. They can even team up to divide 15!

  • Want to learn how they do it?

Dive in and discover how dividing by 3 and 5 makes problem-solving a breeze!

Meet the Stars: 3 and 5!

Get ready! Today, your star numbers—3 and 5—will show off their division skills. See how they can split up other numbers!

The Amazing Number 3

First up is number 3! You probably have three of something—like friends, toys, or snacks.

When a number can be divided by 3 evenly, it’s divisible by 3. To find these numbers, just keep adding 3s together.

Here's how it works

3 + 3 = 6, so 6 is divisible by 3.

3 + 3 + 3 = 9, so 9 is divisible by 3.

3 + 3 + 3 + 3 = 12, so 12 is divisible by 3.

3 + 3 + 3 + 3 + 3 = 15, so 15 is divisible by 3.

And you can keep going!

For 6, write the expression like this.

6 ÷ 3 = 2

Six divided by three equals two.

  • But did you notice something about the 2?

If you look at the chart, 2 is the amount of 3s added together to make 6!

So, 3 goes into 6 two times.

It's the same with 9, 12, and 15. Three goes into 9 three times. On the chart, there are three 3s added together.

It's like a jigsaw puzzle where everything fits!

  • Quick Question: Is 3 divisible by itself?

Yes! Every number (except 0) is divisible by itself, and the answer is always 1.

The Amazing Number 5

Now, check out number 5! You’ve probably used 5 a lot—think about 5 fingers on your hand.

Numbers divisible by 5 are easy to spot. You just keep adding 5s. Here are some.

5, 10, 15, 20

The expressions look like this.

5 ÷ 5 = 1

10 ÷ 5 = 2

15 ÷ 5 = 3

20 ÷ 5 = 4

  • Do you see a pattern?

5 divides into these numbers perfectly!

The Jobs of Numbers

Here is something else that numbers do. They have jobs!

In a division problem, every number has a job.

divisor: the number doing the dividing (like 3 or 5)

dividend: the number being divided

quotient: the result or answer

Here you can see all the jobs.

number jobs for 21 divided by 3 equals 7

Fun Fact: Any number divisible by another number is called divisible by that number. For example, 21 is divisible by 3!
