Year 6 to Year 7 maths: what changes and how to prepare
Year 7 maths adds integers, algebra and ratios. What changes after Year 6, what Term 4 orientation involves, and how to help your child prepare.
Read the guideKey points
Year 7 maths adds integers, index notation, ratios and formal algebra to the arithmetic your child met in Year 6.
Victorian government secondary schools hold Orientation Day on Tuesday 8 December 2026. In New South Wales public schools, Year 7 placement was confirmed in September 2026, with orientation activities in December.
Australian research links the move to secondary school with a small dip in maths performance that does not appear when students change primary schools.
The Year 6 skills that carry the most weight in Year 7 are fractions, decimals, percentages and factors, so short, regular practice across Term 4 is more useful than a rush in January.
Where Year 6 families are up to right now
Term 4 is the last term of primary school for this year's Year 6 students. In Victoria, Term 4 runs from Monday 5 October to Friday 18 December 2026 [1]. In New South Wales, Term 4 runs from Tuesday 13 October to Thursday 17 December 2026, with the summer holidays starting on Friday 18 December [2].
Placement for 2027 is already settled in both systems. Under the Victorian statewide timeline, secondary schools notified families of 2027 placement outcomes on 24 June 2026, acceptance was due on 11 August, and Orientation Day for Year 6 students is Tuesday 8 December 2026 [3].
In New South Wales public schools, expressions of interest were due in March 2026, the enrolling high school confirmed placement in September 2026, and students attend orientation activities at their new school in December 2026 before Year 7 starts in February 2027 [4].
That leaves most of a term in which the subject matter is still primary maths, while the expectations your child will meet are about to change.
What is new in Year 7 maths?
Year 7 is the first year of the secondary maths curriculum. Under version 9 of the Australian Curriculum, the genuinely new ground includes the following.
Integers. In Year 6, students recognise situations involving positive and negative numbers and locate them on a number line and in the coordinate plane. In Year 7, they compare, order, add and subtract integers and solve problems with them [5][6].
Index notation, squares and roots. Year 7 students write natural numbers as products of prime factors using exponents, and solve problems involving perfect squares and square roots [6].
Algebra. Year 7 introduces variables in everyday formulas, building expressions with constants, variables, operations and brackets, solving one-variable linear equations with natural-number solutions, and creating tables of values to plot on the Cartesian plane [6].
Ratios. Students recognise, represent and solve problems involving ratios, and model practical problems using rational numbers, percentages and ratios [6].
All four operations with fractions. Year 6 covers adding and subtracting fractions using equivalent fractions, along with the four operations with decimals. Year 7 extends this to multiplying and dividing positive fractions as well [5][6].
Measurement formulas. Areas of triangles and parallelograms, volumes of right prisms, the relationship between a circle's radius, diameter and circumference, and angle relationships involving parallel lines [6].
Statistics with summary measures. Year 7 students calculate summary statistics, identify outliers and justify their choice of a measure of central tendency [6].
Which Year 6 skills matter most in Year 7?
Four areas do the heaviest lifting.
Fractions. Ordering common fractions, using equivalent fractions, and adding and subtracting fractions with related denominators are Year 6 content and are assumed when Year 7 moves to multiplying and dividing fractions [5][6]. Printable fractions worksheets (/worksheets/maths/topic/fractions) are a straightforward way to keep this current, and there is more detail in our guide on helping your child with fractions at home (/learn/help-your-child-with-fractions-at-home).
Decimals and percentages. Year 6 includes finding a familiar fraction, decimal or percentage of a quantity, including percentage discounts, and all four operations with decimals [5]. Year 7 then asks students to move between equivalent forms of rational numbers and percentages [6]. See the decimals and percentages worksheets (/worksheets/maths/topic/decimals-and-percentages).
Number properties. Describing prime, composite and square numbers in Year 6 is the direct foundation for writing numbers as products of prime factors in Year 7 [5][6]. The number properties worksheets (/worksheets/maths/topic/number-properties) cover factors, multiples and primes.
Multiplication and division facts. Quick recall underpins almost everything above, including prime factorisation and work with ratios. The multiplication and division worksheets (/worksheets/maths/topic/multiplication-and-division) give short, repeatable practice.
If you are not sure where your child sits, is my child on track (/learn/is-my-child-on-track) sets out what the Australian Curriculum expects at each primary year level.
Does maths achievement dip after primary school?
There is Australian evidence that it can. A 2015 study in the Australian Journal of Educational and Developmental Psychology used differences in state school structures together with data from the Longitudinal Study of Australian Children to estimate the effect of the secondary transition on maths performance. It found a small decline associated with the transition, which held after controlling for known predictors of maths performance, and which did not appear when students moved between primary schools [7].
A 2021 report prepared by the Australian Council for Educational Research for Life Education Australia asked students directly. Researchers ran 82 forums with 444 students from 15 schools across New South Wales, Queensland, South Australia and Western Australia, mostly Year 6 students before the move and Year 7 students after it [8]. Academic expectations, meaning both the level of work and the amount of it, were among the most common sources of strong feeling, positive and negative. The report's literature review cites an earlier Australian study in which up to a third of students reported a difficult or somewhat difficult transition, and research describing social support from family, friends and school as a major protective factor against depression during that period [8].
The practical reading is that the expectations change faster than the mathematics does. A student who can still handle Year 6 content confidently in February has one less thing to manage.
What can you do in Term 4?
Keep practice short and regular. Ten focused minutes most days is easier to sustain through a busy final term than a long weekend session, and it keeps skills available rather than half-remembered.
Work on named skills, not year levels. "Equivalent fractions" or "percentage of an amount" gives you something to practise and something to check. "Year 6 maths" does not.
Use the orientation day. It is the one point before February where you can ask the secondary school directly about maths.
Treat January as maintenance. Six weeks is long enough for recall to fade. A few short sessions a week on facts, fractions and decimals is enough.
Check the equipment list early. Many secondary schools expect a particular calculator, geometry set or workbook from the first week.
What to ask at the orientation day
How are Year 7 maths classes grouped, and when is that decided?
Is there a maths assessment in the first few weeks, and what does it cover?
What calculator and equipment are expected?
How and when will we hear if our child is finding maths difficult?

Common questions
What new maths topics does Year 7 introduce?
Year 7 adds integer addition and subtraction, index notation with prime factors, squares and square roots, ratios, and formal algebra: variables in formulas, building expressions, solving linear equations and plotting tables of values on the Cartesian plane.
Which Year 6 maths skills matter most for Year 7?
Equivalent fractions and adding or subtracting fractions with related denominators, the four operations with decimals, finding a fraction, decimal or percentage of a quantity, and prime, composite and square numbers. Quick recall of multiplication facts supports all of them.
Does maths achievement drop in the first year of high school?
Australian research using longitudinal data found the move to secondary school was associated with a small decline in maths performance. The same effect did not appear when students changed primary schools, which points to the transition itself rather than the move alone.
