Dividing by 4

**Division** means splitting a number into equal groups.

In the last lesson, you learned how to divide numbers by 3.

Now, let’s learn how to divide numbers by 4. 😎

👉 There are **3 ways **to divide by 4:

1. Divide by **grouping.**

2. Divide by **repeated subtraction.**

3. Divide by **multiplying.**

You can use any of these methods! 🤗

👉 Let's look at an example.

16 ÷4= ?

To divide a number by 4 using grouping, just **split it into 4 equal groups**. The number in each group is the answer.

Let's try!

✅ Here, we need to **split the number 16 into 4 equal groups**.

So, what answer did you get?

Very good! 👍 **4.**

16 ÷4=4

To divide a number by 4 using repeated subtraction, **subtract 4 from it over and over again**, till you reach 0. The number of subtractions is the answer to the division problem.

Let's try this method too!

16 ÷4= ?

✅ Let's **start at 16 and subtract 4** over and over again.

How many times did you subtract? 🤓

Very good! 👍 **4 times.**

So,

16 ÷4=4

Nice job! 😺

**Secret trick:** Turn any division equation into a **related **multiplication equation!

If you see **16 ÷ 4 = ****?** , think about it's whole-part diagram:

Are you missing a part or the whole? We're missing a part.

We can rewrite that same whole-part diagram as a multiplication equation:

4 x?= 16

Do you know what number times 4 equals 16?

Yes, 4 x 4 is 16.

So we know that **16 ÷ 4 = ****4**! 🎉

**Remember**: Division is the opposite of multiplication. If you know your multiplication tables, then you already know your division, too!

**Tip**: Try to get really fast at division, just like you did with multiplication. Memorize all of the answers so you **just know **them.

👉 Let's try another equation.

28 ÷4= ?

First, let's find the answer using **grouping**.

What answer did you get?

Great work! 👍 **7.**

28 ÷4=7

Now, let's find the answer using **repeated subtraction.**

What answer did you get this time?

Correct! **7** again.

28 ÷4=7

Awesome!

**Secret trick:** Turn **28 ÷ 4 = ? **into a multiplication problem in your head quickly.

Just think about the whole part diagram. Are you missing a part or the whole?

You're missing a part. Let's write a multiplication problem with a missing part:

4 x ? = 28

**Remember:** Multiplication and division are **related**. The same whole-part diagram can make both a division and a multiplication equation!

So what number times 4 equals 28?

4 x 7 = 28!

So we know that **28 ÷ 4 = 7**! 🎉

Memorize these: 😺

4 ÷ 4 = 1

8 ÷ 4 = 2

12 ÷ 4 = 3

16 ÷ 4 = 4

20 ÷ 4 = 5

24 ÷ 4 = 6

28 ÷ 4 = 7

32 ÷ 4 = 8

36 ÷ 4 = 9

40 ÷ 4 = 10

Great job! Now try the practice.
