### QUESTION 1 of 10

In this activity, you will be challenged to round numbers to the nearest 1000, 10,000 and decimal place.

Let's recap the rules:

Rounding to the nearest 1000

When rounding to the nearest 1000, count in 1000s either side of your number and choose the nearest.

82345 is between 82000 and 83000

82000 < -----82345 ----------------> 83000

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.

• Question 1

Can you round 98,456 to the nearest 1000?

98000
EDDIE SAYS
98,456 is between 98,000 and 99,000, it closest to 98,000 so is rounded down to the nearest 1000. That's a good effort, now let's practise more...
• Question 2

Can you round 66,321 to the nearest 10,000?

70000
EDDIE SAYS
How did you find rounding to the nearest 10,000? 66,321 is between 60,000 and 70,000, it's closest to 70,000 so is rounded up to the nearest 10,000.
• Question 3

Can you round 7.54 to one decimal place?

7.5
EDDIE SAYS
So this time we're looking at a decimal number. Remember to look at the second digit after the decimal point. In this case, it was 4 so we left the digit to the left of it the same (5) and reached the answer 7.5.
• Question 4

The numbers have been rounded to the nearest 10,000.

Can you match each number correctly once it has been rounded?

## Column B

457,216
460,000
111,301
110,000
969,001
970,000
822,464
820,000
EDDIE SAYS
Remember, when we round to the nearest 10,000, we count in 10,000s either side of the number and select the nearest.
• Question 5

The numbers have been rounded to one decimal place.

Can you match each number correctly once it has been rounded?

## Column B

12.42
12.4
38.89
38.9
111.13
111.1
87.85
87.9
EDDIE SAYS
When we round to one decimal place, we must look at the second digit after the decimal point and then round accordingly. You're getting good at this! You're halfway through.
• Question 6

The numbers have been rounded to two decimal places.

Can you match each number correctly once it has been rounded?

## Column B

3.928
3.93
18.111
18.11
264.478
264.48
910.269
910.27
EDDIE SAYS
This time the rule changed. When we round to two decimal places, we must look at the third digit after the decimal point and round accordingly.
• Question 7

Can you complete the blank space by rounding 987,669 to the nearest 10,000?

EDDIE SAYS
How did you find this one? 987,669 is between 980,000 and 990,000 but it is nearest to 990,000.
• Question 8

Can you complete the blank space by rounding 564.368 to two decimal places?

EDDIE SAYS
Here we were asked to round to two decimal places. To do this, we must look at the third digit after the decimal point (8) and then round up to 564.37.
• Question 9

Can you round 995,678 to the nearest 10,000?

1,000,000
1000000
EDDIE SAYS
995,678 is between 990,000 and 1,000,000 but it is closest to 1,000,000. Therefore, we round up to 1,000,000 or 1 million.
• Question 10

Can you round 28,924.643 to two decimal places?

28,924.64
28924.64
EDDIE SAYS
Did you remember to look at the third digit after the decimal point? Because it's a 3, we leave the 4 to the left of it the same, making the answer 28,924.64. Great work, you’ve completed another activity!
