Rounding is not only a rule about five or more. Students need to know which place is being rounded, which digit decides the direction and why the rounded answer is useful.
The Daily Maths Review rounding and estimation app keeps that focus clear. Teachers can choose rounding, estimate sums, money totals or mixed practice, then choose whether students round to 10, 100, 1000, $1 or $10.
Start with the rounding place
Before students answer, ask them to identify the place they are rounding to. The same number can round differently depending on whether the target is tens, hundreds or thousands, so the place needs to be spoken before the rule is applied.
- Use nearest 10 when students are building the basic rounding rule.
- Use nearest 100 or 1000 when place-value thinking is the focus.
- Use estimate sums when students can round each term before adding.
- Use money totals when students are ready to connect estimation to everyday amounts.
Connect rounding to reasonable answers
Estimation helps students check whether an exact answer is plausible. After a few rounding questions, switch to sums or money totals and ask students why the estimate should be close to the exact total.
Run three nearest-10 questions, pause to name the deciding digit, then switch to estimate sums using the same round-to place.
Use answers to choose the next model
If students round from the wrong place, return to a place-value chart. If they forget the deciding digit, mark it. If estimation sums are difficult, model rounding each term before asking students to add.
