Rounding means changing a number to a nearby number that is easier to work with, while keeping it close in value.
Rounding helps make numbers simpler for estimation, mental math, and problem solving.
When rounding, look at the digit in the place value you are rounding to. Then check the digit to its right to decide whether to round up or keep it the same.
Always check the digit to the right of the place value to know whether to round up or stay the same.
You may be asked to round to the nearest ten, hundred, thousand, ten thousand, or hundred thousand. The process is the same each time.
Each place value builds on the last. Always focus on the place you are rounding to and the digit right next to it.
Rounding helps when estimating costs, distances, or totals quickly without needing the exact number.
Use rounding when you need an estimate, not the exact value.
