Rounding chart — nearest ten and hundred
One page with the rounding rule, two number lines and a table of worked examples, for rounding whole numbers to the nearest ten and the nearest hundred.
How to round a number
- Find the place you are rounding to (tens or hundreds) and underline that digit.
- Look at the digit just to its right.
- If it is 0, 1, 2, 3 or 4, keep the underlined digit. If it is 5, 6, 7, 8 or 9, add 1 to it.
- Change every digit to the right of the underlined place to 0.
The number line shows why: 34 is closer to 30 than to 40, and 37 is closer to 40. A number exactly halfway, like 35 or 250, rounds up.
