 3.  Lesson 1 of 10

Imagine you have 4 bags with 3 apples in each bag. How many apples do you have? 
You could count every apple, or add 3 + 3 + 3 + 3. But there is a faster way: **
multiplication**. Multiplication is a quick way to add **equal groups**. In this
lesson you will learn what multiplication means and how to write it.

## Equal groups

Groups are **equal** when each group has the same number of things.

  |  Situation |  Equal groups? |  
   |  3 plates with 4 cookies each |  Yes |  
 |  2 boxes with 6 pencils each |  Yes |  
 |  1 bag with 2 marbles and 1 bag with 5 marbles |  No |

We can only multiply when the groups are equal.

### Describing equal groups

We describe equal groups like this: “**4 groups of 3**“. The first number tells 
how many groups. The second number tells how many are in each group.

## Writing multiplication

“4 groups of 3” is written as a **multiplication sentence**:

**4 × 3 = 12**

 * The symbol **×** means “times” or “groups of”.
 * 4 and 3 are called **factors**.
 * 12, the answer, is called the **product**.

### Repeated addition

Multiplication is the same as adding the same number again and again:

  |  Repeated addition |  Multiplication |  Product |  
   |  3 + 3 + 3 + 3 |  4 × 3 |  12 |  
 |  5 + 5 |  2 × 5 |  10 |  
 |  2 + 2 + 2 + 2 + 2 + 2 |  6 × 2 |  12 |

When there are many groups, multiplication is much faster than writing out all the
additions.

## Multiplication in real life

We use multiplication all the time, even if we do not notice it:

 * There are 7 days in a week. How many days are in 3 weeks? 3 × 7 = 21.
 * A spider has 8 legs. How many legs do 2 spiders have? 2 × 8 = 16.
 * Eggs often come in boxes of 6. How many eggs are in 4 boxes? 4 × 6 = 24.

### Example

Ms Lee is setting up for art class. She puts 5 tables in the room and places 4 paintbrushes
on each table. How many paintbrushes does she need?

There are 5 equal groups of 4. We write **5 × 4**. Adding, 4 + 4 + 4 + 4 + 4 = 20.
So 5 × 4 = **20** paintbrushes.

> Tip: When you see the words “each”, “every” or “per” in a problem, think about
> equal groups. Multiplication might be the tool you need.

### Drawing equal groups

You can always draw a picture to help. Draw a circle for each group, then put the
same number of dots in each circle. Count the dots to find the product. Pictures
are a great way to check your thinking.

## Key takeaways

 * Multiplication is a fast way to add equal groups.
 * “4 groups of 3” is written 4 × 3.
 * The numbers we multiply are factors; the answer is the product.
 * Words like “each” and “every” often signal multiplication.

## Practice

Write a multiplication sentence and find the product:

 1. 3 groups of 5
 2. 6 + 6 + 6 + 6
 3. 2 cars with 4 wheels each

Answers: 1 is 3 × 5 = 15. 2 is 4 × 6 = 24. 3 is 2 × 4 = 8 wheels.
