When you round numbers to the nearest 10, 100 or 1,000, you need to consider whether your number is closer to e.g. 30 or 40, 300 or 400, 3,000 or 4,000.

For example, you might be asked to round 3,457 to the nearest 100.

If you counted **up,** the first number in the 100 times table would be 3,500

If you counted **down**, the first number in the 100 times table would be 3,400

3,457 is between 3,400 and 3,500

But it is closer to 3,500

The digit in the** tens** column is **5**, so the number rounds** up to 3,500 **to the nearest 100.

**Examples**

359 is closer to 400 than 300.

The digit in the** tens** column is **5,** so it rounds **up** to 400 to the nearest 100.

75 is halfway between 70 and 80.

In this case, we round **up** to 80 because the digit in the **ones column **is **5.**

3,499 is nearer to 3,000 than to 4,000.

The digit in the **hundreds column** is **4**, so we round **down** to 3,000 to the nearest 1,000.

It's all about the digit in the column to the right!

Let's have a go at the questions..
