Algebra

• AC9M3A01Recognise and explain the connection between addition and subtraction as inverse operations, apply to partition numbers and find unknown values in number sentences
• AC9M3A02Extend and apply knowledge of addition and subtraction facts to 20 to develop efficient mental strategies for computation with larger numbers without a calculator
• AC9M3A03Recall and demonstrate proficiency with multiplication facts for \(3, 4, 5\) and \(10\); extend and apply facts to develop the related division facts

Measurement

• AC9M3M01Identify which metric units are used to measure everyday items; use measurements of familiar items and known units to make estimates
• AC9M3M02Measure and compare objects using familiar metric units of length, mass and capacity, and instruments with labelled markings
• AC9M3M03Recognise and use the relationship between formal units of time including days, hours, minutes and seconds to estimate and compare the duration of events
• AC9M3M04Describe the relationship between the hours and minutes on analog and digital clocks, and read the time to the nearest minute
• AC9M3M05Identify angles as measures of turn and compare angles with right angles in everyday situations
• AC9M3M06Recognise the relationships between dollars and cents and represent money values in different ways

Number

• AC9M3N01Recognise, represent and order natural numbers using naming and writing conventions for numerals beyond 10 000
• AC9M3N02Recognise and represent unit fractions including \(\frac12\), \(\frac13\), \(\frac14\), \(\frac15\) and \(\frac1{10}\) and their multiples in different ways; combine fractions with the same denominator to complete the whole
• AC9M3N03Add and subtract two- and three-digit numbers using place value to partition, rearrange and regroup numbers to assist in calculations without a calculator
• AC9M3N04Multiply and divide one- and two-digit numbers, representing problems using number sentences, diagrams and arrays, and using a variety of calculation strategies
• AC9M3N05Estimate the quantity of objects in collections and make estimates when solving problems to determine the reasonableness of calculations
• AC9M3N06Use mathematical modelling to solve practical problems involving additive and multiplicative situations including financial contexts; formulate problems using number sentences and choose calculation strategies, using digital tools where appropriate; interpret and communicate solutions in terms of the situation
• AC9M3N07Follow and create algorithms involving a sequence of steps and decisions to investigate numbers; describe any emerging patterns

Probability

• AC9M3P01Identify practical activities and everyday events involving chance; describe possible outcomes and events as ‘likely’ or ‘unlikely’ and identify some events as ‘certain’ or ‘impossible’ explaining reasoning
• AC9M3P02Conduct repeated chance experiments; identify and describe possible outcomes, record the results, recognise and discuss the variation

Space

• AC9M3SP01Make, compare and classify objects, identifying key features and explaining why these features make them suited to their uses
• AC9M3SP02Interpret and create two-dimensional representations of familiar environments, locating key landmarks and objects relative to each other

Statistics

• AC9M3ST01Acquire data for categorical and discrete numerical variables to address a question of interest or purpose by observing, collecting and accessing data sets; record the data using appropriate methods including frequency tables and spreadsheets
• AC9M3ST02Create and compare different graphical representations of data sets including using software where appropriate; interpret the data in terms of the context
• AC9M3ST03Conduct guided statistical investigations involving the collection, representation and interpretation of data for categorical and discrete numerical variables with respect to questions of interest
