In this activity, we will have the challenge of rounding numbers to the nearest 1,000, 10,000 and one or two decimal places. So, a right mixture to keep you on your toes!

Let's recap the rules:

**Rounding to the nearest 1,000**

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

**82,345** is between **82,000** and** 83,000**

**82,000** < -----82,345 ----------------> **83,000**

It is closer to **82,000,** so it is rounded down to **82,000.**

**Rounding to the nearest 10,000**

When rounding to the nearest 10,000, count in 10,000s either side of your number and choose the nearest.

**542,356** is between **540,000** and **550,000.**

**540,000** <------542,356 ------------------->** 550,000**

It is closer to **540,000** so it is rounded down to **540,000.**

**Rounding to one decimal place**

Look at the second digit after the decimal point.

So, for** 8.42**, we look at the **2,** it is less than **5 **so we leave the **4** to the left of it the same.

**8.42 **rounded to one decimal place is **8.4****.**

**Rounding to two decimal places**

Look at the third digit after the decimal place.

**3.928**...the third digit is **8** because it is more than** 5**, you round the **2 **to the left of it, up to **3.**

**3.928 **rounded to two decimal places is** 3.93****.**

How do you feel about all that?
