Achievement standard (what coverage means)
- •Students conduct guided statistical investigations involving categorical and discrete numerical data, and interpret their results in terms of the context.
- •They use mathematical modelling to solve practical problems involving single-digit multiplication and division, recalling multiplication facts for twos, threes, fours, fives and tens, and using a range of strategies.
- •They create algorithms to investigate numbers and explore simple patterns.
- •Students represent unit fractions and their multiples in different ways.
- •Students use familiar metric units when estimating, comparing and measuring the attributes of objects and events.
- •By the end of Year 3, students order and represent natural numbers beyond 10 000.
- •They represent money values in different ways.
- •Students extend and use single-digit addition and related subtraction facts and apply additive strategies to model and solve problems involving two- and three-digit numbers.
- •Students make, compare and classify objects using key features.
- •Students find unknown values in number sentences involving addition and subtraction.
- •Students estimate and compare measures of duration using formal units of time.
- •They conduct repeated chance experiments and discuss variation in results.
- •They make estimates and determine the reasonableness of financial and other calculations.
- •They partition, rearrange and regroup two- and three-digit numbers in different ways to assist in calculations.
- •Students use practical activities, observation or experiment to identify and describe outcomes and the likelihood of everyday events explaining reasoning.
- •They interpret and create two-dimensional representations of familiar environments.
- •They identify angles as measures of turn and compare them to right angles.
- •They record, represent and compare data they have collected.
- 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
- 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
- AC9M3N01recognise, represent and order natural numbers using naming and writing conventions for numerals beyond 10 000
- AC9M3N02recognise 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
- 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
- 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
- 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
