Number and Algebra
Number and place value (F-8)
Recall addition facts for single-digit numbers and related subtraction facts to develop increasingly efficient mental strategies for computation (ACMNA055)
  • recognising that certain single-digit number combinations always result in the same answer for addition and subtraction, and using this knowledge for addition and subtraction of larger numbers
  • combining knowledge of addition and subtraction facts and partitioning to aid computation (for example 57 + 19 = 57 + 20 – 1)

Number and Algebra
Fractions and Decimals (1-6)
Model and represent unit fractions including 1/2, 1/4, 1/3, 1/5 and their multiples to a complete whole (ACMNA058)
  • partitioning areas, lengths and collections to create halves, thirds, quarters and fifths, such as folding the same sized sheets of paper to illustrate different unit fractions and comparing the number of parts with their sizes
  • locating unit fractions on a number line
  • recognising that in English the term ‘one third’ is used (order: numerator, denominator) but that in other languages this concept may be expressed as ‘three parts, one of them’ (order: denominator, numerator) for example Japanese

Number and Algebra
Money and financial Maths (1-10)
Represent money values in multiple ways and count the change required for simple transactions to the nearest five cents (ACMNA059)
  • recognising the relationship between dollars and cents, and that not all countries use these denominations and divisions (for example Japanese Yen)

  • recognising and using centimetres and metres, grams and kilograms, and millilitres and litres
  • recognising the importance of using common units of measurement
  • recognising that metric units are not the only units used throughout the world, for example measuring the area of floor space using tatami mats (Japan), using squares for room and house area (Australia) and miles for distance (Britain, USA)
