Year 4: Australian Curriculum v9

Listed Mathematics content descriptions at Year 4, in the words of the Australian Curriculum, Assessment and Reporting Authority (ACARA), with the practice on this site that covers it. Checked against the source on 4 September 2026.

Taught as published in South Australia, and as the Australian Curriculum in Queensland (ACiQ). The Northern Territory, the ACT and Tasmania also teach it directly. Content descriptions are verbatim from ACARA's curriculum workbook.

Coverage is the percentage of listed content descriptions with at least one linked practice skill; it does not measure how fully every part of an entry is practised. A skill can practise more than one content description, so some appear more than once below.

Number

  1. AC9M4N01recognise and extend the application of place value to tenths and hundredths and use the conventions of decimal notation to name and represent decimals

  2. AC9M4N02explain and use the properties of odd and even numbers

  3. AC9M4N03find equivalent representations of fractions using related denominators and make connections between fractions and decimal notation

  4. AC9M4N04count by fractions including mixed numerals; locate and represent these fractions as numbers on number lines

  5. AC9M4N05solve problems involving multiplying or dividing natural numbers by multiples and powers of 10 without a calculator, using the multiplicative relationship between the place value of digits

  6. AC9M4N06develop efficient strategies and use appropriate digital tools for solving problems involving addition and subtraction, and multiplication and division where there is no remainder

  7. AC9M4N07choose and use estimation and rounding to check and explain the reasonableness of calculations including the results of financial transactions

  8. AC9M4N08use mathematical modelling to solve practical problems involving additive and multiplicative situations including financial contexts; formulate the problems using number sentences and choose efficient calculation strategies, using digital tools where appropriate; interpret and communicate solutions in terms of the situation

  9. AC9M4N09follow and create algorithms involving a sequence of steps and decisions that use addition or multiplication to generate sets of numbers; identify and describe any emerging patterns

Algebra

  1. AC9M4A01find unknown values in numerical equations involving addition and subtraction, using the properties of numbers and operations

  2. AC9M4A02recall and demonstrate proficiency with multiplication facts up to 10 x 10 and related division facts; extend and apply facts to develop efficient mental strategies for computation with larger numbers without a calculator

Measurement

  1. AC9M4M01interpret unmarked and partial units when measuring and comparing attributes of length, mass, capacity, duration and temperature, using scaled and digital instruments and appropriate units

  2. AC9M4M02recognise ways of measuring and approximating the perimeter and area of shapes and enclosed spaces, using appropriate formal and informal units

  3. AC9M4M03solve problems involving the duration of time including situations involving “am” and “pm” and conversions between units of time

  4. AC9M4M04estimate and compare angles using angle names including acute, obtuse, straight angle, reflex and revolution, and recognise their relationship to a right angle

Space

  1. AC9M4SP01represent and approximate composite shapes and objects in the environment, using combinations of familiar shapes and objects

  2. AC9M4SP02create and interpret grid reference systems using grid references and directions to locate and describe positions and pathways

  3. AC9M4SP03recognise line and rotational symmetry of shapes and create symmetrical patterns and pictures, using dynamic geometric software where appropriate

Statistics

  1. AC9M4ST01acquire data for categorical and discrete numerical variables to address a question of interest or purpose, using digital tools; represent data using many-to-one pictographs, column graphs and other displays or visualisations; interpret and discuss the information that has been created

  2. AC9M4ST02analyse the effectiveness of different displays or visualisations in illustrating and comparing data distributions, then discuss the shape of distributions and the variation in the data

  3. AC9M4ST03conduct statistical investigations, collecting data through survey responses and other methods; record and display data using digital tools; interpret the data and communicate the results

Probability

  1. AC9M4P01describe possible everyday events and the possible outcomes of chance experiments and order outcomes or events based on their likelihood of occurring; identify independent or dependent events

  2. AC9M4P02conduct repeated chance experiments to observe relationships between outcomes; identify and describe the variation in results
