What children learn in Level 10
- 48,312 fans came to a game. To the nearest ten thousand, that's between 40,000 and 50,000.
- 48,312 is past the halfway point, 45,000, so it rounds to 50,000. About 50,000 fans!
- To the nearest hundred thousand, find the two hundred thousands. 352,817 is between 300,000 and 400,000.
- The halfway point is 350,000, and 352,817 is just past it. So it rounds up to 400,000.
- The same number can round differently: 352,817 is about 350,000 to the nearest ten thousand, but about 400,000 to the nearest hundred thousand.
