- Determine the two consecutive multiples of 10 that bracket 821
- 821 is between 820 and 830
- 825 is the midpoint between 820 and 830
- As illustrated on the number line, 821 is less than the midpoint (825)
- Therefore, 821 rounded to the nearest ten = 820
821 rounded to the nearest ten with a number line
