Integers on Number Lines and the Cartesian Plane
Use zero as a reference point to interpret positive and negative integers in finance, position, coordinates, movement and temperature
ExampleDuring a class investigation, a student reasons, “−8 is greater than −3 because 8 is greater than 3”. Which response corrects the error?
Official curriculum wording
recognise situations, including financial contexts, that use integers; locate and represent integers on a number line and as coordinates on the Cartesian plane
Prime, Composite and Square Numbers
Use factor structure to classify numbers and simplify calculations
ExampleWhich number is a prime number?
Official curriculum wording
identify and describe the properties of prime, composite and square numbers and use these properties to solve problems and simplify calculations
Equivalent Fractions on a Common Number Line
Compare halves, thirds, quarters and related fractions and justify their order
ExampleDuring a class investigation, a student reasons, “Larger denominator means larger value”. Which response corrects the error?
Official curriculum wording
apply knowledge of equivalence to compare, order and represent common fractions including halves, thirds and quarters on the same number line and justify their order
Adding and Subtracting Decimals
Use place value, efficient strategies, estimation and digital verification
ExampleDuring a class investigation, a student reasons, “Decimal points not aligned”. Which response corrects the error?
Official curriculum wording
apply knowledge of place value to add and subtract decimals, using digital tools where appropriate; use estimation and rounding to check the reasonableness of answers
Adding and Subtracting Fractions
Use equivalent fractions, benchmarks and mixed-number interpretation
ExampleDuring a class investigation, a student reasons, “Numerators and denominators both added”. Which response corrects the error?
Official curriculum wording
solve problems involving addition and subtraction of fractions using knowledge of equivalent fractions
Multiplying and Dividing Decimals by Powers of 10
Track changing digit value and factor multiples of ten
ExampleDuring a class investigation, a student reasons, “Add zeros rule used with decimals”. Which response corrects the error?
Official curriculum wording
multiply and divide decimals by multiples of powers of 10 without a calculator, applying knowledge of place value and proficiency with multiplication facts; using estimation and rounding to check the reasonableness of answers
Fractions, Decimals and Percentages of Quantities
Find familiar parts, discounts and remaining amounts efficiently
ExampleDuring a class investigation, a student reasons, “Discount amount reported as final price”. Which response corrects the error?
Official curriculum wording
solve problems that require finding a familiar fraction, decimal or percentage of a quantity, including percentage discounts, choosing efficient calculation strategies and using digital tools where appropriate
Estimating with Rational Numbers and Percentages
Choose bounds, compatible numbers and safe financial estimates
ExampleDuring a class investigation, a student reasons, “Nearest rounding used automatically”. Which response corrects the error?
Official curriculum wording
approximate numerical solutions to problems involving rational numbers and percentages, including financial contexts, using appropriate estimation strategies
Mathematical Modelling with Rational Numbers and Percentages
Formulate, solve, validate and justify practical and financial decisions
ExampleDuring a class investigation, a student reasons, “Every number in the context used”. Which response corrects the error?
Official curriculum wording
use mathematical modelling to solve practical problems involving natural and rational numbers and percentages, including in financial contexts; formulate the problems, choosing operations and efficient calculation strategies, and using digital tools where appropriate; interpret and communicate solutions in terms of the situation, justifying the choices made
