Multiplying by 4

Let's review. 🤓

What is multiplication?

Multiplicationis repeated addition.

It's important to remember this because you'll be doing a lot of multiplication in 3rd grade!

When we **multiply a number by 4,** it's like **adding **equal groups **four times.**

For example:

4 x 4=?

... is the same as:

4 + 4 + 4 + 4=?

Let's draw 4 groups, with 4 stars in each group.

If we count the stars altogether, we'll have 16 stars.

So we see that 4 x 4 is 16!

Do you know what 8 x 4 is?

If you don't, just skip count by one of the numbers to find out. Then memorize it!

We can skip count by either factor. Let's pick 8, and skip count by 8, four times:

8, 16, 24, 32

So 8 x 4 = 32!

You can use skip counting to solve any multiplication problem you don't know, but then it's really important to memorize the answers!

**Multiplication tables **shows what different numbers multiplied together equal.

Here's the multiplication table for 4.

👇 **Memorize these numbers!**

4 x 1 = 4

4 x 2 = 8

4 x 3 = 12

4 x 4 = 16

4 x 5 = 20

4 x 6 = 24

4 x 7 = 28

4 x 8 = 32

4 x 9 = 36

4 x 10 = 40

4 x 11 = 44

4 x 12 = 48

Great work! 👏

🤓 **Tip: **multiplying a number by 4 always gives you an **even **number.

Now, you can move on to practice! 💪
