GUIDED PRACTICES
Rounding to the nearest tens the number in the ones place let you know if you round up or down.
Example: 43 → 40
Rounding to the nearest hundreds the number in the tens place let you know if you round up or down
Example: 650 → 700
Rounding to the nearest thousands place the number in the hundreds let you know if you round up or down
Example: 2399 → 2000
