Taught alongside it

The rest of Algebra in Year 3.

AC9M3A01

recognise and explain the connection between addition and subtraction as inverse operations, apply to partition numbers and find unknown values in number sentences

AC9M3A03

recall and demonstrate proficiency with multiplication facts for \(3, 4, 5\) and \(10\); extend and apply facts to develop the related division facts

The same idea, year by year

Where AC9M3A02 comes from and where it goes, for a student working below or above Year 3.

  1. Year 2AC9M2A01recognise, 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
  2. Year 2AC9M2A02recall and demonstrate proficiency with addition facts to 20; extend and apply facts to develop related subtraction facts
  3. Year 2AC9M2A03recall and demonstrate proficiency with multiplication facts for twos; extend and apply facts to develop the related division facts using doubling and halving
  4. Year 4AC9M4A01find unknown values in numerical equations involving addition and subtraction, using the properties of numbers and operations
  5. Year 4AC9M4A02recall and demonstrate proficiency with multiplication facts up to 10 x 10 and related division facts; extend and apply facts to develop efficient mental strategies for computation with larger numbers without a calculator
