By Year 5 the numbers in NAPLAN numeracy reach the tens of thousands, decimals arrive in hundredths, and many questions take two or three steps. The test runs 50 minutes, online. This page compares what ACARA says a Year 5 student at the Developing and Strong levels can do, because the gap between those two levels explains where most effort pays off. Then it teaches compensation, the habit of rounding to a friendly number, calculating, and correcting the difference, with practice questions we wrote. We teach numeracy only, not the literacy tests, and we promise no level.
Year 5 facts from ACARA · Questions written by us · Numeracy only
In short
Year 5 NAPLAN numeracy runs for 50 minutes online. Students sit it straight after conventions of language, on a day their school picks inside the national window, 10 to 22 March in 2027. For the Strong level, ACARA's Year 5 description lists comparing numbers beyond 10 000, representing hundredths as decimals, spotting equivalent fractions and solving simple multi-step problems.

Year 5 is the first NAPLAN in which every test is done online, including writing. For numeracy that means tailored testlets: each student starts on the same first set of questions, and the next set depends on how the first went. A careless error early on matters more than a slow answer.
Five extra minutes compared with Year 3 does not mean five extra minutes of rest. Questions now chain operations together, so reading carefully and checking each step is where time goes.
ACARA notes that a few questions reach content from the year of testing and the year after. For Year 5 that can include ideas many classes finish in Year 6, such as adding fractions with the same denominator.
Its advice on preparation is short: teach the curriculum. The practice on this page follows that advice. It is one strategy, taught properly, rather than a pile of mock tests.

Reading the Year 5 descriptions
Quoted from ACARA's Year 5 numeracy descriptions. The pairing of lines is our own, to show the step.
| Idea | Developing: the student can | Strong: the student can |
|---|---|---|
| Size of numbers | compare, order and represent numbers to 10 000 | compare, order and represent numbers beyond 10 000 |
| Decimals | represent tenths as decimal numbers | represent hundredths as decimals |
| Fractions | compare fractions and identify the fraction to complete a whole | identify equivalent fractions |
| Operations | solve single-step problems with operations including division, where there are no remainders | solve simple multi-step problems with operations |
| Patterns | continue number patterns using addition or multiplication with whole numbers | continue number patterns using addition and multiplication with whole numbers, simple fractions and decimals |
| Time | determine and order the duration of an event using clocks and calendars | calculate duration including am/pm notation and conversion between units |
Two words carry most of the step: hundredths and multi-step. A Developing student handles one operation on whole numbers; a Strong student strings operations together and works in decimals to two places.
At the Exceeding level ACARA adds skills such as "add and subtract decimals and fractions with the same denominator", "calculate areas and perimeters of rectangles" and "interpret timetables in context". Each of those is a multi-step task in disguise.
Compensation helps with both words. It turns an awkward number into a friendly one, so a two-step problem becomes two easy steps, and it works the same way for 3.99 as for 399.
It also builds the checking habit. The correction at the end forces a child to ask what they changed, and by how much, which is the reasoning a multi-step question demands.

Practice we wrote
Change one number to something easy, do the easy calculation, then undo the change. The method is the same for whole numbers, decimals, multiplication and time.
299 + 146: add 300 instead, giving 446, then take back the extra 1. The answer is 445.
504 minus 198: subtract 200 to get 304, then give back the 2 you over-subtracted. The answer is 306.
6 times 49: 6 times 50 is 300, but that counts one extra 6, so subtract 6. The answer is 294.
| Question | Friendly version | Correction | Answer |
|---|---|---|---|
| A school prints 299 newsletters on Monday and 146 on Tuesday. How many in total? | 300 + 146 = 446 | Used 1 too many, so subtract 1 | 445 |
| A tank holds 504 litres. 198 litres are drained. How much is left? | 504 minus 200 = 304 | Took 2 too many, so add 2 | 306 litres |
| Each of 6 teams runs 49 laps. How many laps altogether? | 6 times 50 = 300 | Counted 6 extra laps, so subtract 6 | 294 laps |
| A ribbon of 3.99 m is joined to one of 2.45 m. Total length? | 4 + 2.45 = 6.45 | Added 0.01 too much, so subtract 0.01 | 6.44 m |
| A garden bed is 19 m by 6 m. What is its area? | 20 times 6 = 120 | One extra strip of 6 square metres, so subtract 6 | 114 square metres |
| How far is 637 from 1 000? | 999 minus 637 = 362, with no regrouping | 999 is 1 short of 1 000, so add 1 | 363 |
| A train leaves at 9:52 am and arrives at 11:17 am. How long is the trip? | 9:52 to 10:00 is 8 minutes; 10:00 to 11:17 is 1 hour 17 minutes | Add the two parts | 1 hour 25 minutes |
The sixth question is a favourite of teachers because it removes the regrouping that causes so many slips. Subtracting from 999 never needs borrowing, and the correction of one is easy to remember. The last question is compensation with time: instead of counting minutes across the hour, a student rounds to 10:00 first, which is the timetable skill ACARA lists at the Exceeding level.
Every answer also comes with a free check. If 6 times 49 came out larger than 300, something went wrong, because 49 is smaller than 50. Estimation and compensation are two sides of the same idea.
Where Year 5 marks slip away
From our own teaching, not from NAPLAN data.
Correcting in the wrong direction: rounding 198 up to 200 when subtracting, then subtracting the extra 2 instead of adding it back.
Lining up decimals by the last digit, so 3.99 + 2.4 is treated as 3.99 + 0.24.
Answering the first step of a two-step question and stopping there.
Reading 9:52 to 11:17 as 1 hour 65 minutes, by subtracting the clock digits separately.
Say the change out loud: "I took away 2 too many." The sentence tells you which way to correct.
Write whole numbers with a decimal point and zeros, so 2.4 becomes 2.40 before adding.
Before answering, reread the question and circle what it asks for.
Bridge to the next whole hour first, then count the rest, exactly as in the timetable question above.
Calculation, flexibly
A child climbs these at their own pace; the year level is only a rough guide.
| Rung | In practice | Ready to move on when |
|---|---|---|
| 1. Partitioning | Splits numbers into hundreds, tens and ones | Add 346 and 238 in their head, place by place |
| 2. Compensation | Rounds, calculates, corrects | Explain why 504 minus 198 means adding 2 back |
| 3. Decimals | Uses the same moves with tenths and hundredths | Add 3.99 and 2.45 without a written method |
| 4. Multi-step | Chains operations and checks each one | Solve the garden-bed area and its perimeter in one go |
By Year 5 some children have decided they are "not a maths person". Small wins with a reliable strategy change that story faster than extra homework.
Praise the explanation, not just the answer.
Year 7 adds the non-calculator section and proportional reasoning; our Year 7 numeracy page continues the story.

Questions about Year 5 NAPLAN numeracy
50 minutes, taken after the conventions of language test within the national window.
Inside the national window of 10 to 22 March 2027. Your school chooses the day.
Yes. From Year 5 every NAPLAN test is online, writing included; only Year 3 writes on paper. Numeracy uses item types such as drag-and-drop and hot-spot.
ACARA describes the non-calculator section and online calculator for Years 7 and 9 only; it describes no calculator for Year 5.
A mental strategy: change a number to a friendly one, calculate with it, then correct for the change. For example, 299 + 146 becomes 300 + 146, then subtract 1, giving 445.
Among other skills, ACARA lists comparing numbers beyond 10 000, representing hundredths as decimals, identifying equivalent fractions and solving simple multi-step problems.
In ACARA's wording, Developing students work with numbers to 10 000, tenths and single-step problems; Strong students work beyond 10 000, with hundredths and with simple multi-step problems.
No. We teach mathematics only.
We promise no level or score. We teach the mathematics carefully, and that is what the test asks students to use.
We agree a weekly time after the free trial. Adelaide is five hours ahead of India time during daylight saving, so a 4.30 pm class begins at 11.30 am India time.
