NAPLAN Numeracy is designed to assess how students apply mathematics knowledge, skills, procedures and processes in different contexts. The assessment is aligned with the Australian Curriculum.
Year 5 students may encounter questions involving:
- Number and algebra
- Measurement and geometry
- Statistics and probability
- Mathematical reasoning
- Problem solving
- Interpreting tables, graphs, diagrams and other representations
NAPLAN is not a pass or fail test. Student performance is reported across four proficiency levels: Exceeding, Strong, Developing and Needs additional support.
The assessment is one source of information about a student’s learning. It should be considered alongside classroom assessment, teacher feedback and other evidence of progress.
NAPLAN Year 5 Maths Topics
Understanding the major content areas gives students a useful starting point for preparation.
1. Number and Algebra
Number and algebra form a major part of Year 5 Numeracy. Students need to be comfortable working with whole numbers, fractions, decimals, operations and patterns.
Important skills include:
- Reading, comparing and ordering numbers
- Addition and subtraction
- Multiplication and division
- Multiplication facts
- Fractions and equivalent fractions
- Decimals, including tenths
- Number patterns
- Number sentences
- Unknown values
- Odd and even numbers
- Using mathematical relationships to solve problems
Students should also understand which operation is appropriate for a particular problem.
For example, a question may describe a real life situation rather than simply asking students to calculate 36 × 4. The student must first understand what the question is asking and then select the correct operation.
2. Measurement
Measurement questions can involve everyday situations and require students to select appropriate units or calculate measurements.
Students should practise:
- Length
- Mass
- Capacity
- Area
- Perimeter
- Time
- Duration
- Metric units
- Reading scales
- Converting between common units
Students should know when to use units such as millimetres, centimetres, metres, grams, kilograms, millilitres and litres.
Time is also important. Students should be able to read analogue and digital clocks, compare times and calculate elapsed time.
3. Geometry and Space
Geometry questions test how well students understand shapes, angles, position and movement.
Key areas include:
- 2D shapes
- 3D objects
- Properties of shapes
- Angles
- Symmetry
- Maps
- Grid references
- Directions
- Position and movement
- Pathways
- Representations of 3D objects
Students should become familiar with mathematical language such as parallel, perpendicular, symmetry, angle, vertex and face.
NAPLAN proficiency descriptions show that stronger Year 5 students may be expected to interpret angles, describe pathways, identify lines of symmetry and interpret 2D representations of 3D objects.
4. Statistics and Data
Year 5 students need to understand how information is represented and how to use data to answer questions.
Common areas include:
- Tables
- Tally charts
- Column graphs
- Picture graphs
- Two way tables
- Comparing data
- Finding patterns in data
- Making predictions
- Checking statements against data
A question may provide a graph and ask students to determine which statement is correct. The challenge is often understanding the information before performing any calculation.
5. Chance and Probability
Chance questions focus on the likelihood of different outcomes.
Students should understand terms such as:
- Certain
- Likely
- Unlikely
- Impossible
- Equally likely
They may need to compare events or determine the possible outcomes of a simple chance experiment.
6. Problem Solving and Reasoning
NAPLAN Numeracy is not only about performing calculations. Students also need to apply mathematics to problems and explain or identify appropriate reasoning.
A student may need to:
- Identify relevant information
- Decide which operation to use
- Interpret a diagram
- Recognise a pattern
- Compare different possibilities
- Work through more than one step
- Check whether an answer makes sense
The current NAPLAN assessment framework places emphasis on fluency, understanding, problem solving and reasoning.

How to Prepare for NAPLAN Year 5 Maths
Effective preparation should focus on understanding rather than simply completing questions quickly.
Review Core Maths Skills
Start with the areas your child finds difficult.
Review:
- Multiplication and division facts
- Fractions
- Decimals
- Measurement
- Time
- Geometry
- Data
- Probability
- Number patterns
- Word problems
A short diagnostic quiz can help identify gaps before creating a study plan.
Practise Word Problems
Many students can perform calculations but struggle when mathematics is presented as a written problem.
Encourage your child to ask:
- What information is given?
- What do I need to find?
- Which operation should I use?
- Is there more than one step?
- Does my answer make sense?
This approach helps students become more independent problem solvers.
Practise Different Question Formats
NAPLAN Numeracy can include multiple choice, text entry and technology enhanced questions such as drag and drop and hot spot questions.
Students should therefore practise more than traditional worksheet questions.
The official NAPLAN public demonstration site is useful for familiarising students with question types and online features.
Build Mental Maths Skills
Encourage students to calculate simple problems mentally before reaching for a written method.
Useful skills include:
- Multiplication facts
- Division facts
- Number bonds
- Place value
- Estimation
- Mental addition
- Mental subtraction
- Fraction relationships
Strong mental maths skills can help students work more efficiently.
Teach Students to Check Their Answers
An incorrect answer is not always caused by a lack of mathematical knowledge.
Students can make mistakes because they:
- Read the question too quickly
- Choose the wrong operation
- Misread a graph
- Forget a unit
- Make a calculation error
- Miss an important piece of information
Teach your child to pause and check whether the answer is reasonable.
NAPLAN Year 5 Maths Tips for Students
Read Every Question Carefully
Do not rush to calculate. First understand what the question is asking.
Look at Units
Pay attention to words such as metres, centimetres, kilograms, litres, dollars and minutes.
Use Estimation
If the exact answer is not obvious, estimate first. This can help identify an unreasonable answer.
Draw a Diagram
For geometry, measurement and some word problems, a simple drawing can make the problem easier to understand.
Look for Patterns
When numbers repeat or change in a particular way, look for the mathematical rule before selecting an answer.
Do Not Spend Too Long on One Question
If a question is difficult, use the available information and your best strategy. Avoid allowing one question to affect your confidence with the rest of the assessment.
How Parents Can Support Year 5 NAPLAN Maths Preparation
Parents do not need to turn home study into a second classroom.
Small, regular practice sessions can be more useful than long study sessions.
Try using everyday activities such as:
- Comparing prices while shopping
- Calculating change
- Reading timetables
- Measuring ingredients
- Comparing distances
- Looking at sports statistics
- Reading charts and graphs
- Estimating quantities
These activities show children that mathematics is useful outside school.
If your child repeatedly struggles with the same concept, targeted support can be more effective than simply giving them additional worksheets.
One to one online maths tutoring can provide personalised explanations, guided practice and feedback based on the student’s individual needs.
