Large Numbers: Round Numbers to the Nearest

In this worksheet, we will round numbers to the nearest 1000, 10 000, 100 000 and 1 000 000.

 

Rounding to the nearest 1000 (thousand)

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

 

93 235 is between 93 000 and 94 000.

 

93 000 <——93 235——————> 94 000

 

It is closer to 93 000 so...

93 235 is 93 000 rounded to the nearest 1000.

 

 

Rounding to the nearest 10 000 (ten thousand)

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

 

369 594 is between 360 000 and 370 000.

 

360 000 <—————369 594 ———> 370 000

 

It is closer to 370 000 so...

369 594 is 370 000 rounded to the nearest 10 000.

 

 

Rounding to the nearest 100 000 (hundred thousand)

When rounding to the nearest 100 000, count in 100 000s either side of your number and choose the nearest.

 

8 439 798 is between 8 400 000 and 8 500 000.

 

8 400 000 <———8 439 798—————> 8 500 000

 

It is closer to 8 400 000 so...

8 439 798 is 8 400 000 rounded to the nearest 100 000. 

 

 

Rounding to the nearest 1 000 000 (million)

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

 

8 500 000 is between 8 000 000 and 9 000 000.

 

8 000 000 <———8 500 000———> 9 000 000

 

It is halfway, so we round up to 9 000 000 so...

8 500 000 is 9 000 000 rounded to the nearest 1 000 000.
