- Determine the two consecutive multiples of 10 that bracket 321
- 321 is between 320 and 330
- 325 is the midpoint between 320 and 330
- As illustrated on the number line, 321 is less than the midpoint (325)
- Therefore, 321 rounded to the nearest ten = 320
321 rounded to the nearest ten with a number line
