How to prepare for Year 5 NAPLAN Maths: Topics, Practice & Questions

NAPLAN Year 5 Maths, officially called the Numeracy test, is a 50-minute online assessment covering number, algebra, measurement, space, statistics and probability. Students complete a short non-calculator section first, and an on-screen calculator unlocks only for the second half of the test. This guide sets out every topic tested, walks through real practice questions with worked answers, and shares practical, evidence-based tips to help Year 5 students walk into the test room with confidence rather than anxiety.

Maths Topics Covered in NAPLAN Year 5

NAPLAN Year 5 Numeracy draws directly from the Australian Curriculum v9.0 maths content for Years 4 and 5. Broadly, the test questions fall into three groups.

Number and Algebra

• Place value of whole numbers up to millions
• Addition, subtraction, multiplication and division, including multi-digit problems
• Multiplication facts to 10 x 10, plus related factors and multiples
• Equivalent fractions, comparing fractions, and adding or subtracting fractions with the same denominator
• Decimal place value, and converting simple fractions to decimals
• Introductory percentages, including finding simple percentages of a quantity
• Number patterns, missing number problems, and simple algebraic reasoning

Measurement and Space

• Converting units of length, mass and capacity, such as millimetres to centimetres or grams to kilograms
• Calculating the perimeter and area of rectangles and simple composite shapes
• Reading and calculating time, including the 24 hour clock, timetables and elapsed time
• Identifying and measuring angles, including acute, obtuse, right and reflex angles
• Properties of 2D shapes and 3D objects
• Symmetry, and transformations such as reflection, rotation and translation
• Using grid references and simple coordinates to describe location

Statistics and Probability

• Reading and interpreting column graphs, line graphs and picture graphs
• Collecting, organising and displaying data
• Answering questions that require comparing or combining data from a graph or table
• Using probability language such as likely, unlikely, certain and impossible
• Expressing simple probabilities as fractions

NAPLAN Year 5 Maths Practice Questions

Practising a mix of question types is one of the most effective ways to build familiarity with the test format. Here are five sample questions in the style of NAPLAN Year 5 Numeracy, with worked answers.

1. Number: Addition

Question: 3,482 + 4,769 = ?

Answer: 8,251. Line up the digits by place value and add from the ones column, carrying over where needed.

2. Fractions

Question: 3/8 + 2/8 = ?

Answer: 5/8. When denominators match, simply add the numerators and keep the denominator the same.

3. Measurement: Perimeter

Question: A rectangle is 12 cm long and 7 cm wide. What is its perimeter?

Answer: 38 cm. Perimeter equals two times the length plus two times the width, so 2 x 12 plus 2 x 7 equals 38 cm.

4. Time

Question: A train departs at 14:35 and the trip takes 55 minutes. What time does it arrive, using the 24 hour clock?

Answer: 15:30. Add 55 minutes to 14:35, carrying the extra hour once the minutes pass 60.

5. Statistics

Question: A column graph shows that 18 students chose soccer and 12 students chose netball as their favourite sport. How many more students chose soccer than netball?

Answer: 6 students. Subtract the smaller value from the larger value, 18 minus 12 equals 6.

Tips to Prepare for NAPLAN Year 5 Maths

Official guidance from education authorities is clear that students should not be pushed into intensive cramming for NAPLAN. That said, steady, low-pressure practice throughout the year genuinely helps students feel calm and capable on test day.

• Practise mental maths for ten to fifteen minutes a few times a week, rather than long cramming sessions
• Work through official released NAPLAN past papers to get used to the question style and online format
• Practise on a device with a timer, since the real test is online and timed
• Identify weak topics early using practice questions, then spend extra time on those specific areas
• Build familiarity with key maths vocabulary, since NAPLAN questions are often worded differently to classroom worksheets
• Keep a consistent sleep routine and a good breakfast in the lead up to test week
• Reassure your child that NAPLAN is one snapshot of learning, not a measure of their overall ability
