Dividing by 3

Do you remember what it means to divide? 🤔

That’s right!

**Division** means breaking a bigger number into smaller, equal groups.

In the last lesson, you learned how to divide numbers by 2.

Now, let’s learn how to divide numbers by 3. 😎

👉 There are **3 methods **to divide a number by 3.

1. Division by **grouping.**

2. Division by **repeated subtraction.**

3. Division by** multiplication.**

You can use any of these methods! 🤗

👉 Let's look at an example.

9 ÷3= ?

Let's solve this equation.

To divide a number by 3 using grouping, just **split it into 3 equal groups. **The number in each group is the answer.

Let's try!

✅ Here, we need to **split the number 9 into 3 equal groups.**

So, what answer did you get?

Very good! 👍 **3.**

9 ÷3=3

To divide a number by 3 using repeated subtraction, **subtract 3 from it over and over again**, till you reach 0. The number of times you subtract is the answer to the division problem.

Let's try this method, too!

9 ÷3= ?

✅ Let's **start at 9 and subtract 3** over and over again.

How many times did you subtract? 🤓

Very good! 👍 **3 times.**

So,

9 ÷3=3

Nice job! 👏

If you see a division problem like 9 ÷ 3 = **?**, you can rewrite it as a multiplication problem:

3 x?= 9

Can you think of what number times 3 equals 9?

Yes! 3 x **3** equals 9.

👉 Let's try another equation.

27 ÷3= ?

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

What answer did you get? 🤓

Great work! 👍 **9**.

27 ÷3=9

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

What answer did you get this time? 😃

Correct! **9** again.

27 ÷3=9

Awesome! 😎

To solve 27 ÷ 3 = ?, just rewrite is as a multiplication problem:

3 x ? = 27

Do you know what number times 3 equals 27?

Yes, 3 x 9 is 27.

So 27 ÷ 3 = 9! 🎉

It might help to memorize these!

3 ÷ 1 = 1

6 ÷ 3 = 2

9 ÷ 3 = 3

12 ÷ 3 = 4

15 ÷ 3 = 5

18 ÷ 3 = 6

21 ÷ 3 = 7

24 ÷ 3 = 8

27 ÷ 3 = 9

30 ÷ 3 = 10

Great job! Now, you know how to divide by 3!
