Rounding Worksheets: Nearest Ten and Hundred
Rounding chooses a nearby multiple. Read whether the question asks for tens or hundreds before deciding.
Find the two nearby multiples
To round 347 to the nearest ten, compare 340 and 350. The distances are seven and three. Since 350 is closer, 347 rounds to 350.
Nearest ten: 347 is between 340 and 350; choose 350.
Nearest hundred: 347 is between 300 and 400; choose 300.
The requested place changes the answer
The same number can round differently when the question changes. For hundreds, compare neighboring hundreds directly. Do not first round to tens and then round that result to hundreds: 349 rounds directly to 300, but rounding it to 350 first would lead to 400.
What happens exactly halfway?
345 is halfway between 340 and 350. In this activity, choose the greater multiple, 350. Likewise, 350 rounds to 400 when the question asks for the nearest hundred.
Zero and one thousand can be correct
24 is closer to 0 than to 100, so it rounds to 0 to the nearest hundred. For 980, compare 900 and 1,000; it rounds to 1,000. The rounded answer can have fewer or more digits than the original number.
An exact multiple stays the same
340 is already a multiple of ten, so it rounds to 340 to the nearest ten. A number does not need to change merely because the instruction says to round.
Connect distance to the digit shortcut
For the nearest ten, the ones digit shows whether the number is below, at, or above the midpoint. For the nearest hundred, the last two digits show the distance from the lower hundred. Explain that distance first, then use the familiar digit rule.
About this practice
Each set contains six distinct number-and-place questions from the original bank. Numbers range from 10 through 989, with requests for the nearest 10 or 100. The key gives the rounded value. Write neighboring multiples or a short distance comparison in the working space.
Sets do not guarantee both rounding places, a halfway case, or a boundary answer. Decimal rounding and rounding to thousands are not included. A hand-drawn number line can support the reasoning; these printable questions do not include pre-drawn number lines.

After the practice
Choose one number and round it to both tens and hundreds. Ask why the two answers can differ and verify each with nearby multiples.
