Everything the Year 5 NAPLAN Numeracy test covers, and how to practise it
By Year 5, most students have sat NAPLAN Numeracy once before, but the questions ask more of them than they did in Year 3. A single question now often chains two or three steps together instead of one, fractions and percentages start carrying real weight, and the reading load inside each question goes up.
There is still no calculator at this year level, so everything has to be worked out by hand or in your child's head. That single fact is the thing families most often assume has changed by Year 5 and it has not.
What does Year 5 NAPLAN Numeracy cover?
| Topic | What it looks like at this year level |
|---|---|
| Number | Fractions, decimals and percentages start doing real work, alongside multi-step word problems with whole numbers. |
| Measurement | Area and perimeter of rectangles, unit conversions like grams to kilograms, and working out elapsed time. |
| Algebra | Extending a number pattern with a bigger jump between terms, and solving a number sentence that now takes more than one step. |
| Space | Properties of 2D and 3D shapes, including lines of symmetry and simple turns. |
| Statistics | Working out the mean or median of a small data set and reading a graph with a scaled axis or a symbol key. |
| Probability | Listing every possible outcome of a simple chance experiment, and saying whether those outcomes are equally likely. |
Like every online NAPLAN test, Year 5 Numeracy is adaptive: a strong run of answers moves your child onto harder questions, and that is the test working as intended, not a sign of trouble. The real step up from Year 3 is that a single question now often needs two or three operations chained together rather than one, and there is still no calculator at this year level, so the working has to happen on paper or in your child's head.

Get startedSample Year 5 NAPLAN Numeracy questions
These are original questions written in the style of NAPLAN. Real test questions are ACARA copyright and are not published for practice use.
Number
A jumper costs $60. In a sale the price is reduced by 25%. What is the sale price?
Answer: $45, from 25% of $60 being $15, then $60 minus $15
The most common wrong answer here is $15, the discount itself, mistaken for the price.
Measurement
A rectangular pool is 12 m long and 5 m wide. What is its perimeter, in metres?
Answer: 34 m, from 12 + 5 + 12 + 5
Perimeter and area get mixed up constantly at this year level; the giveaway word here is around, not the area formula.
Statistics
Five students scored 14, 14, 9, 20 and 18 out of 20. What is the median score?
Answer: 14, the middle value once the scores are ordered: 9, 14, 14, 18, 20
Finding the median without ordering the data first is one of the most common slips at Year 5.
Probability
A fair six-sided die is rolled once. What is the probability of rolling a number greater than 4?
Answer: 2/6, which simplifies to 1/3
Only 5 and 6 satisfy greater than 4, so the total number of possible outcomes matters as much as the two that work.
Common Numeracy mistakes at Year 5
Adds the denominators when adding fractions
When adding fractions, adds the numerators and the denominators separately, so 1/2 + 1/3 is answered as 2/5.
Fix
Re-teach with area models that show why unlike-sized parts cannot be counted together, and practise finding a common denominator as its own step before any addition.
Mixes up perimeter and area
Multiplies the side lengths when asked for the perimeter, or adds them when asked for the area.
Fix
Tie each word to an action: perimeter is walking the fence, area is covering the floor with squares. Ask your child to name which action the question wants before any calculation.
Muddles a pattern's position and its value
When asked for, say, the tenth term of a pattern, applies the rule from the wrong starting point and counts one step too many or too few.
Fix
Set out a two-row table of position and value and find the rule connecting the rows, so the position number becomes an input to the rule rather than something to count towards.
Ignores the key on a scaled graph
Counts every symbol or every step on the axis as worth one, so a pictograph where each symbol stands for five is read at only a fifth of its real value.
Fix
Make reading the key the compulsory first step on any graph, and write the multiplier next to it before reading a single value off.
How to practise for Year 5 Numeracy
The step up at Year 5 is chaining steps, so a good habit is having your child write down each step of a word problem separately rather than trying to do it all in their head. The most common way marks are lost is stopping after the first correct step and reporting that as the answer.
Fractions, decimals and percentages start doing real work in Year 5 questions, so practice that moves between the three forms of the same amount, one half, 0.5, 50 percent, pays off more than practising each form in isolation.
There is still no calculator, so mental strategies for percentages, finding 10% first and building the target percentage from it, are worth more time than long written methods.
When is the Year 5 NAPLAN in 2027?
The 2027 window is Wednesday 10 March to Monday 22 March 2027. Schools schedule the four tests inside that window, and Writing has to be scheduled for the first day. Most schools finish in the first week, so confirm the exact days with your school rather than a national site.
On the day, Numeracy at Year 5 runs for 50 minutes.
Test structure, marking and reporting facts on this page come from ACARA's public NAPLAN documentation, checked against nap.edu.au in August 2026.
Find the Year 5 Numeracy gaps now, not on test day
Year 5 Numeracy rewards a child who can chain two steps together without losing the first one, and that is a skill practice actually builds.
