Taught alongside it

The rest of Measurement in Year 5.

AC9M5M01

choose appropriate metric units when measuring the length, mass and capacity of objects; use smaller units or a combination of units to obtain a more accurate measure

AC9M5M02

solve practical problems involving the perimeter and area of regular and irregular shapes using appropriate metric units

AC9M5M03

compare 12- and 24-hour time systems and solve practical problems involving the conversion between them

The same idea, year by year

Where AC9M5M04 comes from and where it goes, for a student working below or above Year 5.

  1. 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
  2. Year 4AC9M4M02recognise ways of measuring and approximating the perimeter and area of shapes and enclosed spaces, using appropriate formal and informal units
  3. Year 4AC9M4M03solve problems involving the duration of time including situations involving “am” and “pm” and conversions between units of time
  4. Year 4AC9M4M04estimate and compare angles using angle names including acute, obtuse, straight angle, reflex and revolution, and recognise their relationship to a right angle
  5. Year 6AC9M6M01convert between common metric units of length, mass and capacity; choose and use decimal representations of metric measurements relevant to the context of a problem
  6. Year 6AC9M6M02establish the formula for the area of a rectangle and use it to solve practical problems
  7. Year 6AC9M6M03interpret and use timetables and itineraries to plan activities and determine the duration of events and journeys
  8. Year 6AC9M6M04identify the relationships between angles on a straight line, angles at a point and vertically opposite angles; use these to determine unknown angles, communicating reasoning
