What Year 2 Maths students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 2 Maths standard sentences this code builds towards:
- Students recall and demonstrate proficiency with addition and subtraction facts within 20 and multiplication facts for twos.
- Students locate and identify positions of features in two-dimensional representations and move position by following directions and pathways.
- Students identify and represent part-whole relationships of halves, quarters and eighths in measurement contexts.
- They use mathematical modelling to solve practical additive and multiplicative problems, including money transactions, representing the situation and choosing calculation strategies.
- They compare and classify shapes, describing features using formal spatial terms.
- They describe and continue patterns that increase and decrease additively by a constant amount and identify missing elements in the pattern.
The Measurement progression either side of AC9M2M05
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 1
- AC9M1M01compare directly and indirectly and order objects and events using attributes of length, mass, capacity and duration, communicating reasoning
- AC9M1M02measure the length of shapes and objects using informal units, recognising that units need to be uniform and used end-to-end
- AC9M1M03describe the duration and sequence of events using years, months, weeks, days and hours
Builds towards · Year 3
- 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
Other Year 2 Measurement codes
- 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
- AC9M2M04recognise and read the time represented on an analog clock to the hour, half-hour and quarter-hour
