Taught alongside it

The rest of Measurement in Year 3.

AC9M3M01

identify which metric units are used to measure everyday items; use measurements of familiar items and known units to make estimates

AC9M3M02

measure and compare objects using familiar metric units of length, mass and capacity, and instruments with labelled markings

AC9M3M03

recognise and use the relationship between formal units of time including days, hours, minutes and seconds to estimate and compare the duration of events

AC9M3M04

describe the relationship between the hours and minutes on analog and digital clocks, and read the time to the nearest minute

AC9M3M06

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

The same idea, year by year

Where AC9M3M05 comes from and where it goes, for a student working below or above Year 3.

  1. Year 2AC9M2M01measure and compare objects based on length, capacity and mass using appropriate uniform informal units and smaller units for accuracy when necessary
  2. Year 2AC9M2M02identify common uses and represent halves, quarters and eighths in relation to shapes, objects and events
  3. Year 2AC9M2M03identify the date and determine the number of days between events using calendars
  4. Year 2AC9M2M04recognise and read the time represented on an analog clock to the hour, half-hour and quarter-hour
  5. Year 2AC9M2M05identify, describe and demonstrate quarter, half, three-quarter and full measures of turn in everyday situations
  6. Year 4AC9M4M01interpret unmarked and partial units when measuring and comparing attributes of length, mass, capacity, duration and temperature, using scaled and digital instruments and appropriate units
  7. Year 4AC9M4M02recognise ways of measuring and approximating the perimeter and area of shapes and enclosed spaces, using appropriate formal and informal units
  8. Year 4AC9M4M03solve problems involving the duration of time including situations involving “am” and “pm” and conversions between units of time
  9. Year 4AC9M4M04estimate and compare angles using angle names including acute, obtuse, straight angle, reflex and revolution, and recognise their relationship to a right angle
