In this activity,we will be rounding numbers to the nearest 10, 100, or 1,000.

Rounding numbers means adjusting the numbers (either up or down) to make rough calculations simpler.

**Rounding numbers to the nearest 10:**

If the **ones **digit of the number is **less than 5**, **round** the number **down.**

If the **ones** digit of the number is 5** or more**, **round** the number **up.**

__Example:__ round 32 to the nearest 10:

**30 **<- - -**32** - - - - - - ->** 40**

It is closer to 30, so 32 rounds **down** to 30

__Example__:** round 36 to the nearest 10**:

**30** <- - - - - - **36**- - -> **40**

36 is closer to 40, so 36 rounds **up** to 40.

**Rounding numbers to the nearest 100:**

This time, look at the **tens** digit, if it is** less than 50**,** round down**.

If the tens digit is **50 or more**, **round up**.

__ Example__: round 834 to the nearest 100.

**800** < - - - - **834** - - - - - - - - - - - - >**900**

It is closer to 800, so 834 rounded to the nearest 100 is **800.** It rounds **down.**

**Rounding numbers to the nearest 1,000:**

When rounding to the nearest 1,000, count in 1,000s on either side of your number and choose the closest one.

__ Example:__ round 2,839 to the nearest 1,000

**2,000** <- - - - - - - - - - - - - - - -**2,839** - - - - >** 3,000**

It's closer to 3,000, so 2,839 rounded to the nearest 1,000 is 3,000.
