Rounding numbers is the process of making a number simpler but keeping its value close to what it was. The result is an estimated value (not the exact or actual) and is easier to understand but less accurate.
We are rounding numbers is in our everyday lives without even realizing it. For example, your friend asks you how many pages of worksheets were you able to finish last week? You might say that you finished about 20 pages. It may be 15 or 22, but you know you finished about 20 pages, so you round to the nearest ten.
Is 12 closer to 10 or 20?
Number 12 is between 10 and 20 on the number line. As you can see, 12 is closer because it is only 2 steps away from 10 and 8 steps away from 20. So, we round down 12 to 10.
Step 1: Identify and underline the rounding digit (tens digit) to avoid confusion when rounding large numbers.
Step 2: Look at the digit in the one’s place.
Step 3: Follow the rounding rules.
- If the digit in the ones place is 0, 1, 2, 3, or 4, you need to round down the number. To do it, copy the rounding digit.
- If the digit in the ones place is 5, 6, 7, 8, or 9, you need to round up the number. To do it, add 1 to the rounding digit.
Step 4: Change all the digit/s to its right to zero.
Step 5: All the digit/s to the left remain the same.
