What Year 3 Maths students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 3 Maths standard sentences this code builds towards:
- Students conduct guided statistical investigations involving categorical and discrete numerical data, and interpret their results in terms of the context.
- They use mathematical modelling to solve practical problems involving single-digit multiplication and division, recalling multiplication facts for twos, threes, fours, fives and tens, and using a range of strategies.
- They create algorithms to investigate numbers and explore simple patterns.
- Students represent unit fractions and their multiples in different ways.
- Students use familiar metric units when estimating, comparing and measuring the attributes of objects and events.
- By the end of Year 3, students order and represent natural numbers beyond 10 000.

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 2
- AC9M2N01recognise, represent and order numbers to at least 1000 using physical and virtual materials, numerals and number lines
- AC9M2N02partition, rearrange, regroup and rename two- and three-digit numbers using standard and non-standard groupings; recognise the role of a zero digit in place value notation
- AC9M2N03recognise and describe one-half as one of 2 equal parts of a whole and connect halves, quarters and eighths through repeated halving
Builds towards · 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
Other Year 3 Number codes
- AC9M3N01recognise, represent and order natural numbers using naming and writing conventions for numerals beyond 10 000
- AC9M3N02recognise and represent unit fractions including 1/2, 1/3, 1/4, 1/5 and 1/10 and their multiples in different ways; combine fractions with the same denominator to complete the whole
- AC9M3N03add and subtract two- and three-digit numbers using place value to partition, rearrange and regroup numbers to assist in calculations without a calculator
- AC9M3N04multiply and divide one- and two-digit numbers, representing problems using number sentences, diagrams and arrays, and using a variety of calculation strategies
- AC9M3N05estimate the quantity of objects in collections and make estimates when solving problems to determine the reasonableness of calculations
- AC9M3N07follow and create algorithms involving a sequence of steps and decisions to investigate numbers; describe any emerging patterns
