What Year 3 Maths students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 3 Maths standard sentences this code builds towards:
- 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.
The Measurement progression either side of AC9M3M03
A class can only meet this descriptor if they were taught the one before it. If yours hasn't, that's where the lesson starts — not here.
Taught before · Year 2
- AC9M2M01measure and compare objects based on length, capacity and mass using appropriate uniform informal units and smaller units for accuracy when necessary
- AC9M2M02identify common uses and represent halves, quarters and eighths in relation to shapes, objects and events
- AC9M2M03identify the date and determine the number of days between events using calendars
Builds towards · Year 4
- 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
- AC9M4M02recognise ways of measuring and approximating the perimeter and area of shapes and enclosed spaces, using appropriate formal and informal units
- AC9M4M03solve problems involving the duration of time including situations involving “am” and “pm” and conversions between units of time
Other Year 3 Measurement codes
- 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
- 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
