Quick Query

- How many relatives do you have?

Maybe a sister or brother, cousins, aunts, uncles, grandparents, and don't forget a mom or a dad! You might even have step-parents, second cousins, or great aunties.

Numbers have relatives too. However, their family trees look a lot different.

- For example, how are 9, 1, and 10 related?

They are not cousins. Instead, those numbers are related by addition and subtraction operations!

9 + 1 = 10

1 + 9 = 10

10 - 1 = 9

10 - 9 = 1

- Can you think of any other ways numbers can be related?

Numbers can also be related through multiplication and division!

Let's look at the numbers in the multiplication equation below:

- Notice how each number has an important name?

Much like in your family, these titles matter and help to describe the relationships.

**Factors** are numbers that, when multiplied, make up a **product**. The product is the answer in a multiplication equation.

You can display this multiplication equation with equal groups or an array:

- How are the numbers in this multiplication equation related to division?

Let's look at the product from the equation.

The product is 6. There were 6 total dots in our equal groups drawing.

In a division equation, the product becomes the dividend. The **dividend** is the total amount to be divided or split up.

In this case, the total is 6:

The **divisor** is how many groups the total will be split into. In this case, the dividend will be split into 2 groups:

To find the **quotient** or the answer of a division equation, you will need to divide the 6 total dots into 2 equal groups. Then, count how many dots are in each group!

- Does anything look familiar?

Compare this equal group drawing to the one above. They are the same!

- What about the numbers and the equations? What is similar about them?

- Do you see the relation?

There are two more equations that complete this family.

- Do you know what they are?

Yes! We use the commutative property of multiplication to find these equations in our fact family.
