Sarah wants to know whether the sum of 242+771 is less than 1,000. She rounds both numbers to the nearest 10 and uses the rounded numbers to estimate the sum. 

Owen wants to know the same thing, but he rounds the numbers to the nearest 100 to estimate the sum. 

Calculate their estimates, then say which method you would use to figure out whether the sum is less than 1000.

Sarah: 690+230=920

Owen: 700+200=900

Rounding to the nearest 10 gets you a closer estimate!
