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 Algebra progression either side of AC9M2A02
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
Builds towards · Year 3
- AC9M3A01recognise and explain the connection between addition and subtraction as inverse operations, apply to partition numbers and find unknown values in number sentences
- AC9M3A02extend and apply knowledge of addition and subtraction facts to 20 to develop efficient mental strategies for computation with larger numbers without a calculator
- AC9M3A03recall and demonstrate proficiency with multiplication facts for 3, 4, 5 and 10; extend and apply facts to develop the related division facts
Other Year 2 Algebra codes
- AC9M2A01recognise, describe and create additive patterns that increase or decrease by a constant amount, using numbers, shapes and objects, and identify missing elements in the pattern
- AC9M2A03recall and demonstrate proficiency with multiplication facts for twos; extend and apply facts to develop the related division facts using doubling and halving
