What it is

Rounding makes a number simpler by moving it to the nearest ten, hundred, or thousand — or, for a decimal number, to the nearest whole number, tenth, or hundredth.

Why it matters

Rounding powers estimation, a fast sanity check on any calculation and a key real-world skill for budgeting and measurement.

How to do it

Find the place you are rounding to.
Look at the digit just to its right.
If it is 5 or more, round up; if it is 4 or less, round down (then drop everything to the right of the rounding place).

Examples by level

BeginnerRound 31.96 to the nearest tenth =32.0
IntermediateRound 68.63 to the nearest tenth =68.6
AdvancedRound 255.66 to the nearest tenth =255.7

Examples are generated by the same engine as the worksheets, so they're always mathematically correct. Built to avoid repeats, not reshuffle the same handful of questions.

Common mistakes

Looking at the wrong digit to decide rounding.
Rounding up on digits below five.
For whole numbers, forgetting to zero out the digits after the rounding place; for decimals, dropping them instead of zeroing them.

Tips

5 always rounds up.
Only the digit immediately to the right decides.

For parents

Teach the rule 'five or more, round up; four or less, round down' and always identify the deciding digit first.

For teachers

Connect rounding to estimation tasks so it's a tool for checking answers, not an isolated procedure.

Key vocabulary

round up: move to the higher value
round down: move to the lower value
