In this activity, we are going to learn to make the largest and smallest three-digit numbers from three given digits.

Using **only** the digits 5, 4, and 8, we need to create the largest and smallest three-digit numbers possible.

**We can only use each digit once**.

To make the** largest **number:

Start with the** largest** digit in the **hundreds** place.

This is **8.**

Then comes the next largest digit in the **tens** place.

This is **5.**

Lastly, comes the smallest of the three digits in the ones place.

This is **4**.

The largest possible number is **854 **

We read this as** eight hundred and fifty-four.**

To make the** smallest** number:

Start with the **smallest** digit in the **hundreds** place.

This is **4.**

Then comes the next largest digit in the **tens** place.

This is **5.**

Lastly, comes the largest of the three digits in the **ones** place.

This is **8.**

The smallest number is** 458.**

We read this as **four hundred and fifty-eight**.

Now that you've been shown the method to use, let's try an example question together.

**Example**

Use each of the digits **686 **to form the smallest and largest three-digit numbers that you can make.

**Answer**

6 is the smallest digit.

6 is the middle digit even though it is the same as the smallest here.

8 is the largest digit.

The **smallest** number is 668.

We read that as six hundred and sixty-eight.

The **largest **number is 866

We read that as eight hundred and sixty-six.

Let's try some questions now.
