ACMNA149.b applying knowledge of factors to strategies for expressing whole numbers as products of powers of prime factors, such as repeated division by prime factors or creating factor trees
ACMNA149.c solving problems involving lowest common multiples and greatest common divisors (highest common factors) for pairs of whole numbers by comparing their prime factorisation
ACMNA152.a exploring equivalence among families of fractions by using a fraction wall or a number line (for example by using a fraction wall to show that 2/3 is the same as 4/6 and 6/9)
ACMNA153 Solve problems involving addition and subtraction of fractions, including those with unrelated denominators
ACMNA153.a exploring and developing efficient strategies to solve additive problems involving fractions (for example by using fraction walls or rectangular arrays with dimensions equal to the denominators)
ACMNA154 Multiply and divide fractions and decimals using efficient written strategies and digital technologies
ACMNA154.a investigating multiplication of fractions and decimals, using strategies including patterning and multiplication as repeated addition, with both concrete materials and digital technologies, and identifying the processes for division as the inverse of multiplication
ACMNA157 Connect fractions, decimals and percentages and carry out simple conversions
ACMNA157.a justifying choices of written, mental or calculator strategies for solving specific problems including those involving large numbers
ACMNA157.b understanding that quantities can be represented by different number types and calculated using various operations, and that choices need to be made about each
ACMNA157.c calculating the percentage of the total local municipal area set aside for parkland, manufacturing, retail and residential dwellings to compare land use
ACMNA173 Recognise and solve problems involving simple ratios
ACMNA173.a understanding that rate and ratio problems can be solved using fractions or percentages and choosing the most efficient form to solve a particular problem
ACMNA175 Introduce the concept of variables as a way of representing numbers using letters
ACMNA175.a understanding that arithmetic laws are powerful ways of describing and simplifying calculations and that using these laws leads to the generality of algebra
ACMNA177 Extend and apply the laws and properties of arithmetic to algebraic terms and expressions
ACMNA177.a identifying order of operations in contextualised problems, preserving the order by inserting brackets in numerical expressions, then recognising how order is preserved by convention

ACMSP170.a understanding that some data representations are more appropriate than others for particular data sets, and answering questions about those data sets
ACMSP170.b using ordered stem-and-leaf plots to record and display numerical data collected in a class investigation, such as constructing a class plot of height in centimetres on a shared stem-and-leaf plot for which the stems 12, 13, 14, 15, 16 and 17 have been produced
ACMSP171 Calculate mean, median, mode and range for sets of data. Interpret these statistics in the context of data
ACMSP171.a understanding that summarising data by calculating measures of centre and spread can help make sense of the data
