What Year 5 Maths students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 5 Maths standard sentences this code builds towards:
- They choose and use appropriate metric units to measure the attributes of length, mass and capacity, and to solve problems involving perimeter and area.
- They represent common percentages and connect them to their fraction and decimal equivalents.
- They estimate, construct and measure angles in degrees.
- Students perform and describe the results of transformations and identify any symmetries.
- Students convert between 12- and 24-hour time.
- By the end of Year 5, students use place value to write and order decimals including decimals greater than one.

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 4
- AC9M4N01recognise and extend the application of place value to tenths and hundredths and use the conventions of decimal notation to name and represent decimals
- AC9M4N02explain and use the properties of odd and even numbers
- AC9M4N03find equivalent representations of fractions using related denominators and make connections between fractions and decimal notation
Builds towards · 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
Other Year 5 Number codes
- AC9M5N010create and use algorithms involving a sequence of steps and decisions and digital tools to experiment with factors, multiples and divisibility; identify, interpret and describe emerging patterns
- AC9M5N02express natural numbers as products of their factors, recognise multiples and determine if one number is divisible by another
- AC9M5N03compare and order fractions with the same and related denominators including mixed numerals, applying knowledge of factors and multiples; represent these fractions on a number line
- AC9M5N04recognise that 100% represents the complete whole and use percentages to describe, represent and compare relative size; connect familiar percentages to their decimal and fraction equivalents
- AC9M5N05solve problems involving addition and subtraction of fractions with the same or related denominators, using different strategies
- AC9M5N06solve problems involving multiplication of larger numbers by one- or two-digit numbers, choosing efficient calculation strategies and using digital tools where appropriate; check the reasonableness of answers
- AC9M5N07solve problems involving division, choosing efficient strategies and using digital tools where appropriate; interpret any remainder according to the context and express results as a whole number, decimal or fraction
- AC9M5N08check and explain the reasonableness of solutions to problems including financial contexts using estimation strategies appropriate to the context
