What Year 4 Maths students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 4 Maths standard sentences this code builds towards:
- They recognise equivalent fractions and make connections between fraction and decimal notations.
- Students order events or the outcomes of chance experiments in terms of likelihood and identify whether events are independent or dependent.
- They use mathematical modelling to solve financial and other practical problems, formulating the problem using number sentences, solving the problem choosing efficient strategies and interpreting results in terms of the situation.
- They find unknown values in numerical equations involving addition and subtraction.
- Students use the properties of odd and even numbers.
- They choose rounding and estimation strategies to determine whether results of calculations are reasonable.
The Algebra progression either side of AC9M4A01
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 3
- AC9M3A01recognise and explain the connection between addition and subtraction as inverse operations, apply to partition numbers and find unknown values in number sentences
- AC9M3A02extend and apply knowledge of addition and subtraction facts to 20 to develop efficient mental strategies for computation with larger numbers without a calculator
- AC9M3A03recall and demonstrate proficiency with multiplication facts for 3, 4, 5 and 10; extend and apply facts to develop the related division facts
Builds towards · Year 5
