The Australian Curriculum: Mathematics Version 9.0 sets out what students should learn from Foundation through primary school. For teachers, the challenge is seeing that progression clearly enough to plan lessons, identify gaps and choose work at the right level.
Version 9.0 organises Mathematics into six strands: Number, Algebra, Measurement, Space, Statistics and Probability. Understanding, fluency, reasoning and problem-solving are developed through this content.
This guide summarises the main expectations at each primary year level. It is not a substitute for the full achievement standards, but it shows how mathematical knowledge becomes more demanding from Foundation to Year 6.
How maths develops across primary school
Early learning centres on quantities, counting, simple operations, patterns, comparison and familiar shapes. In the middle primary years, students work with larger numbers, multiplication and division, fractions, metric measurement, data and chance. By Years 5 and 6, they connect fractions, decimals and percentages, use more efficient calculations, interpret more complex data and justify mathematical choices.
Teachers can use primary maths resources to reinforce current concepts while revisiting prerequisite knowledge where needed.
Foundation: building number sense
By the end of Foundation, students connect number names, numerals and positions in the sequence from zero to at least 20. They use counting and subitising to quantify collections, compare collections to at least 20, and partition or combine collections up to 10.
They also represent practical situations involving adding, taking away and equal sharing. Beyond number, students compare length, mass, capacity and duration directly, sequence familiar events, sort familiar shapes, describe position and location, and work with simple data.
Year 1: place value and operations take shape
Year 1 extends number knowledge to at least 120. Students partition two-digit numbers, including into tens and ones, and use equal groups and skip counting in twos, fives and tens.
Addition and subtraction move into problems involving numbers to 20. Students also explore practical grouping and sharing, repeating patterns, informal measurement, shapes, directions and categorical data.
Understanding that a number such as 17 can be partitioned in several ways also lays groundwork for later mental computation.
Year 2: extending number to 1,000
By the end of Year 2, students order and represent numbers to at least 1,000 and partition, rearrange and rename two- and three-digit numbers. They use addition and subtraction facts within 20 and recall multiplication facts for twos.
Fractions are more explicit in measurement contexts when broken down into halves, quarters and eighths. Students solve practical additive and multiplicative problems, including money situations. They also read analogue time to the hour, half-hour and quarter-hour, use calendars, measure with uniform informal units, and represent data.
Well-chosen maths worksheets and activities can reinforce these concepts when students must apply knowledge rather than simply repeat a procedure.
Year 3: multiplication, metric units and unit fractions
Year 3 brings a substantial increase in scope. Students order and represent natural numbers beyond 10,000 and use place value to support calculations with two- and three-digit numbers.
They recall multiplication facts for twos, threes, fours, fives and tens and use multiplication and division in practical problems. They represent unit fractions and their multiples, use familiar metric units, compare angles with right angles, work with formal units of time and represent money values.
Students also collect and compare categorical and discrete numerical data. In probability, they conduct repeated chance experiments and discuss variation in results.
Year 4: decimals and equivalent fractions
In Year 4, students represent tenths and hundredths as decimals and connect fraction and decimal notation. They recognise equivalent fractions, place fractions on number lines and use efficient strategies for the four operations.
They use rounding and estimation to judge whether calculations are reasonable. Measurement expands to scaled instruments, perimeter, area, temperature and duration. Students also work with grid references, symmetry, data displays and chance.
A well made Australian Curriculum maths resources can help consolidate skills across number, measurement, statistics and other primary maths content.
Year 5: factors, percentages and more complex calculation
By Year 5, students work with decimals greater than one, factors and multiples, and fractions with the same or related denominators. They add and subtract fractions and connect common percentages with equivalent fractions and decimals.
Students multiply larger numbers by one- and two-digit numbers and divide by single-digit numbers, using estimation to check their answers. They solve practical and financial problems by choosing appropriate operations.
They also solve perimeter and area problems, convert between 12-hour and 24-hour time, measure angles in degrees, use grid coordinates, work with nets and describe transformations. In statistics, they identify the mode and interpret data distributions.
Year 6: connecting the major ideas
Year 6 brings several strands together. Students work with integers, prime, composite and square numbers, common fractions, decimals and percentages. They add and subtract fractions with related denominators, use all four operations with decimals and find fractions, decimals or percentages of quantities.
They interpret timetables, convert common metric units, use the rectangle area formula and solve problems using angle properties. Coordinate work extends to all four quadrants of the Cartesian plane.
Students compare data distributions and consider statistical claims in the media. In probability, they express likelihood using fractions, decimals and percentages and compare expected and observed frequencies.
What changes most from Foundation to Year 6?
The clearest shift is from representing mathematics to using it flexibly. A Foundation student may show addition with objects. A Year 3 student selects strategies for multiplication. A Year 6 student may decide which operations and estimates suit a multi-step financial problem.
Fractions follow the same progression, moving from equal sharing to unit fractions, equivalent fractions, decimals, percentages and calculations with related denominators. Measurement, space, statistics and probability also return at increasing depth, with more precise language and stronger reasoning requirements.
Using the expectations in your planning
Year-level standards are most useful when they guide decisions rather than become a checklist. Start with the knowledge a task requires. If students struggle, identify the earlier concept underneath the difficulty. If they are secure, increase the reasoning or application required instead of simply adding more questions.
