Recognise and represent unit fractions including 1/2, 1/3, 1/4, 1/5 and 1/10 and their multiples in different ways; combine fractions with the same denominator to complete the whole AC9M3N02

Use 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 AC9M3N06

Follow and create algorithms involving a sequence of steps and decisions to investigate numbers; describe any emerging patterns AC9M3N07

Recognise and explain the connection between addition and subtraction as inverse operations, apply to partition numbers and find unknown values in number sentences AC9M3A01 Extend and apply knowledge of addition and subtraction facts to 20 to develop efficient mental strategies for computation with larger numbers without a calculator AC9M3A02 Recall and demonstrate proficiency with multiplication facts for 3, 4, 5 and 10; extend and apply facts to develop the related division facts AC9M3A03

Identify which metric units are used to measure everyday items; use measurements of familiar items and known units to make estimates AC9M3M01 Measure and compare objects using familiar metric units of length, mass and capacity, and instruments with labelled markings AC9M3M02 Recognise and use the relationship between formal units of time including days, hours, minutes and seconds to estimate and compare the duration of events AC9M3M03 Describe the relationship between the hours and minutes on analog and digital clocks, and read the time to the nearest minute AC9M3M04

Identify angles as measures of turn and compare angles with right angles in everyday situations AC9M3M05

Recognise the relationships between dollars and cents and represent money values in different ways AC9M3M06

Make, compare and classify objects, identifying key features and explaining why these features make them suited to their uses AC9M3SP01

Interpret and create two-dimensional representations of familiar environments, locating key landmarks and objects relative to each other AC9M3SP02

Acquire 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 AC9M3ST01 Create and compare different graphical representations of data sets including using software where appropriate; interpret the data in terms of the context AC9M3ST02 Conduct guided statistical investigations involving the collection, representation and interpretation of data for categorical and discrete numerical variables with respect to questions of interest AC9M3ST03

Identify 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 AC9M3P01 Conduct repeated chance experiments; identify and describe possible outcomes, record the results, recognise and discuss the variation AC9M3P02
