Year 6 maths in Queensland, before high school.

All 24 things the Australian Curriculum sets out for Year 6 maths, the ideas that matter most before Year 7, and simple ways to help at home.

Updated 19 October 2026. Written by the Study Compass team from official sources, listed at the end.

Year 6 is the last year of primary maths in the Australian Curriculum, which Queensland state schools teach.[2] It has 24 content descriptions in six strands: Number, Algebra, Measurement, Space, Statistics and Probability.[1]

A lot of Year 6 is about using what your child already knows with more confidence: fractions with any denominator, percentages of amounts, and decimals without a calculator. These are the ideas Year 7 maths is built on.

The big ideas in Year 6

  • Negative numbers. Integers on a number line and on all four quarters of a coordinate grid.
  • Fractions, decimals and percentages together. Equivalent fractions, adding and subtracting any fractions, and finding a percentage of an amount.
  • Area by formula. Why the area of a rectangle is length times width.
  • Angle facts. Using angles on a straight line and around a point to find a missing angle.
  • Thinking about data. Comparing two data sets and questioning statistics in the news.

All 24 Year 6 maths topics, explained

The descriptions below are in our words. ACARA publishes the official wording.[1]

Number

CodeWhat your child learns
AC9M6N01Use negative numbers (integers) in real situations, including money, and place them on a number line and a coordinate grid.
AC9M6N02Recognise prime, composite and square numbers and use their properties to solve problems and simplify calculations.
AC9M6N03Compare and order common fractions, such as halves, thirds and quarters, on one number line, and explain the order.
AC9M6N04Add and subtract decimals using place value, and check with estimation and rounding.
AC9M6N05Add and subtract fractions by first making equivalent fractions.
AC9M6N06Multiply and divide decimals by 10, 100, 1000 and their multiples without a calculator.
AC9M6N07Find a fraction, decimal or percentage of an amount, including percentage discounts.
AC9M6N08Estimate answers to problems with fractions, decimals and percentages, including money problems.
AC9M6N09Use maths to model and solve real problems with fractions, decimals and percentages, including money, and justify the choices made.

Algebra

CodeWhat your child learns
AC9M6A01Find and use the rule behind growing patterns, including number patterns with fractions and decimals.
AC9M6A02Find unknown values in equations with brackets and more than one operation.
AC9M6A03Design step-by-step algorithms that use a rule to make a set of numbers, and explain the pattern.

Measurement

CodeWhat your child learns
AC9M6M01Convert between metric units of length, mass and capacity, using decimals (1.25 kg is 1250 g).
AC9M6M02Work out why the area of a rectangle is length × width, and use it to solve practical problems.
AC9M6M03Read timetables and itineraries to plan activities and work out how long events and journeys take.
AC9M6M04Use angle facts (angles on a straight line, angles at a point, vertically opposite angles) to find unknown angles.

Space

CodeWhat your child learns
AC9M6SP01Compare the cross-sections of objects and connect them to right prisms.
AC9M6SP02Plot points in all four quadrants of a coordinate grid, and describe how coordinates change when a point moves.
AC9M6SP03Combine slides, flips and turns to make tessellations and other patterns.

Statistics

CodeWhat your child learns
AC9M6ST01Compare two sets of data side by side using mode, range and shape.
AC9M6ST02Spot arguments in the media that use statistics, and question how the data was collected and shown.
AC9M6ST03Plan and run a statistical investigation, refining the question as they go, and report the findings.

Probability

CodeWhat your child learns
AC9M6P01Describe probability as a number from 0 to 1 (or 0% to 100%), and estimate how likely everyday events are.
AC9M6P02Run chance experiments and simulations with more and more trials, and compare the results with what they expected.

Where children often get stuck

  • Unlike denominators. 1/3 + 1/4 isn't 2/7. Both have to become twelfths first. If your child adds the bottoms, go back to drawing the fractions.
  • Moving the decimal point. Multiplying by 10 moves the digits, not the point. Saying "the digits get ten times bigger" works better than "add a zero", which breaks with decimals.
  • Percentage of an amount. 25% of 80 is a quarter of 80. Linking common percentages back to fractions makes most Year 6 percentage questions mental maths.
  • Negative numbers. −8 is smaller than −3. A thermometer or a bank balance helps.

How to help at home

  • Shop the sales. Work out what "30% off" saves on something your child wants.
  • Plan a trip. Use a real timetable to work out leaving times and how long the trip takes. That's AC9M6M03.
  • Talk about the news. When a headline quotes a statistic, ask "How do they know that?"
  • Cook with decimals. A recipe that needs 1.5 kg of flour or 250 mL of milk is unit conversion practice.

Ready for Year 7

Study Compass finds the gaps that make Year 7 maths harder, then plans short daily lessons to close them. Every lesson carries its Australian Curriculum code.
