What Year 5 Maths students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 5 Maths standard sentences this code builds towards:
- They choose and use appropriate metric units to measure the attributes of length, mass and capacity, and to solve problems involving perimeter and area.
- They represent common percentages and connect them to their fraction and decimal equivalents.
- They estimate, construct and measure angles in degrees.
- Students perform and describe the results of transformations and identify any symmetries.
- Students convert between 12- and 24-hour time.
- By the end of Year 5, students use place value to write and order decimals including decimals greater than one.
The Measurement progression either side of AC9M5M03
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 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
Builds towards · Year 6
- AC9M6M01convert between common metric units of length, mass and capacity; choose and use decimal representations of metric measurements relevant to the context of a problem
- AC9M6M02establish the formula for the area of a rectangle and use it to solve practical problems
- AC9M6M03interpret and use timetables and itineraries to plan activities and determine the duration of events and journeys
Other Year 5 Measurement codes
- AC9M5M01choose 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
- AC9M5M02solve practical problems involving the perimeter and area of regular and irregular shapes using appropriate metric units
- AC9M5M04estimate, construct and measure angles in degrees, using appropriate tools including a protractor, and relate these measures to angle names
