Round large whole numbers accurately by checking the place to the right of the one being rounded.
Lesson overview
Number - number and place value
Rounding means finding a nearby number that is easier to use. First decide which place you are rounding to. Then check the place to the right. It tells you whether to round down or round up.
Round to the nearest 10,000
671,800 rounds to 670,000 because it is less than 675,000.
The halfway point decides whether you go up or down.
Round to the nearest 100,000
549,999 rounds to 500,000 because it is below 550,000.
For large numbers, focus on the target place and the halfway point.
