What Year 7 Maths students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 7 Maths standard sentences this code builds towards:
- Students classify polygons according to their features and create an algorithm designed to sort and classify shapes.
- They represent objects two-dimensionally in different ways, describing the usefulness of these representations.
- Students choose between equivalent representations of rational numbers and percentages to assist in calculations.
- Students interpret data in terms of the shape of distribution and summary statistics, identifying possible outliers.
- Students solve problems involving addition and subtraction of integers.
- They solve linear equations with natural number solutions.

A class can only meet this descriptor if they were taught the one before it. If yours hasn't, that's where the lesson starts — not here.
Taught before · Year 6
- AC9M6N01recognise situations, including financial contexts, that use integers; locate and represent integers on a number line and as coordinates on the Cartesian plane
- AC9M6N02identify and describe the properties of prime, composite and square numbers and use these properties to solve problems and simplify calculations
- AC9M6N03apply knowledge of equivalence to compare, order and represent common fractions including halves, thirds and quarters on the same number line and justify their order
Builds towards · Year 8
- AC9M8N01recognise irrational numbers in applied contexts, including square roots and π
- AC9M8N02establish and apply the exponent laws with positive integer exponents and the zero-exponent, using exponent notation with numbers
- AC9M8N03recognise terminating and recurring decimals, using digital tools as appropriate
Other Year 7 Number codes
- AC9M7N01describe the relationship between perfect square numbers and square roots, and use squares of numbers and square roots of perfect square numbers to solve problems
- AC9M7N02represent natural numbers as products of powers of prime numbers using exponent notation
- AC9M7N03represent natural numbers in expanded notation using place value and powers of 10
- AC9M7N05round decimals to a given accuracy appropriate to the context and use appropriate rounding and estimation to check the reasonableness of solutions
- AC9M7N06use the 4 operations with positive rational numbers including fractions, decimals and percentages to solve problems using efficient calculation strategies
- AC9M7N07compare, order and solve problems involving addition and subtraction of integers
- AC9M7N08recognise, represent and solve problems involving ratios
- AC9M7N09use mathematical modelling to solve practical problems, involving rational numbers and percentages, including financial contexts; formulate problems, choosing representations and efficient calculation strategies, using digital tools as appropriate; interpret and communicate solutions in terms of the situation, justifying choices made about the representation
