The same idea, year by year

Where AC9MFN05 comes from and where it goes, for a student working below or above Foundation Year.

  1. Year 1AC9M1N01recognise, represent and order numbers to at least 120 using physical and virtual materials, numerals, number lines and charts
  2. Year 1AC9M1N02partition one- and two-digit numbers in different ways using physical and virtual materials, including partitioning two-digit numbers into tens and ones
  3. Year 1AC9M1N03quantify sets of objects, to at least 120, by partitioning collections into equal groups using number knowledge and skip counting
  4. Year 1AC9M1N04add and subtract numbers within 20, using physical and virtual materials, part-part-whole knowledge to 10 and a variety of calculation strategies
  5. Year 1AC9M1N05use mathematical modelling to solve practical problems involving additive situations including simple money transactions; represent the situations with diagrams, physical and virtual materials, and use calculation strategies to solve the problem
  6. Year 1AC9M1N06use mathematical modelling to solve practical problems involving equal sharing and grouping; represent the situations with diagrams, physical and virtual materials, and use calculation strategies to solve the problem
