When **rounding** numbers to any multiple of 10 (10, 100, 1000, etc), we look at the digit in the column to the **right of the number we are rounding to.**

Rounding to **10** - look at the **ones **column 1**6**

Rounding to **100 **- look at the **tens** column 2**6**1

Rounding to **1,000** - look at the** hundreds** column 5,**6**23

If the digit we are looking at is either **0 1 2 3 4** we round **down.**

If the digit is either **5 6 7 8 9** we round **up**.

Let's have a look at a few examples before you try some.

Round these numbers to the nearest **10**

1**5** - the digit to the right of the tens column is a **5** so we **round up to 20.**

1**2 ** - the digit to the right of the tens column is a** 2 **so we** round down to 10.**

Round these numbers to the nearest **100**

2**7**2 - the digit to the right of the hundreds column is a **7 **so we **round up to 300**

6**4**9 - the digit to the right of the hundreds column is a** 4 **so we** round down to 600**

Round these numbers to the nearest **1,000**

9,**9**99 - the digit to the right of the thousands column is a **9 **so we **round up to 10,000**

6,**4**97 - the digit to the right of the thousands column is a** 4 **so we** round down to 6,000**

Round this number to the nearest 1,000

2**1**99

Even though the tens and ones columns are 9s, we still round down because the hundreds digit is a 1

Now, why don't you have a go at rounding some numbers!
