What Year 8 Maths students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 8 Maths standard sentences this code builds towards:
- By the end of Year 8, students recognise irrational numbers and terminating or recurring decimals.
- Students use mathematical modelling to solve problems using linear relations, interpreting and reviewing the model in context.
- They conduct statistical investigations and explain the implications of obtaining data through sampling.
- Students use 3 dimensions to locate and describe position.
- They use Pythagoras’ theorem to solve measurement problems involving unknown lengths of right-angle triangles.
- They apply the exponent laws to calculations with numbers involving positive integer exponents.

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 7
- 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
Other Year 8 Number codes
- 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
- AC9M8N05use mathematical modelling to solve practical problems involving rational numbers and percentages, including financial contexts; formulate problems, choosing efficient calculation strategies and using digital tools where appropriate; interpret and communicate solutions in terms of the situation, reviewing the appropriateness of the model
