At the supermarket checkout, the total comes up as $17.60 and your child is the one holding the $20 note. Before the cashier counts out the change, you can ask them how much should come back, then listen to how they get there. They might count up to $18 and then to $20, or take $17.60 away from $20 in their head.
That's the kind of maths your child meets in Year 5, and plenty of the year's maths turns up in ordinary moments like this one. Practising at home can be a few of those moments in a week, with your child doing the working out and you listening.
Five everyday places Year 5 maths turns up
Victorian government and Catholic schools teach maths from the Victorian Curriculum, which sets out what students learn in levels. The levels describe what a student can do rather than their year at school, so teachers plan from where each child is. The ideas below each connect to Level 5, and your child may meet some of them a little earlier or later than others in their class.
Money at the shops
Before the checkout, you can ask your child roughly what the shopping will cost. In Level 5, students check whether an answer is reasonable by estimating, and money is one of the places the curriculum names. You can also hand them a budget, such as whether $20 covers the four things on the list, which is the simple financial planning Level 5 includes.
Times tables, with their division partners
Learning the multiplication facts up to belongs to Level 4. In Level 5, your child uses those facts to multiply larger numbers and to divide, and learns that multiplication and division undo each other, so comes with and . In the car, you can ask for a fact and then one of its division partners. A timer isn't needed. What's worth noticing is which facts come straight away and which ones your child builds from a fact they know, like from and one more 6.
Fractions in a recipe
Level 5 students add and subtract fractions whose denominators, the bottom numbers, are the same or related, such as halves, quarters and eighths. This doubled recipe gives a mixed numeral (a whole number and a fraction together), also in Level 5. Your child can check by pouring with measuring cups.
Double the flour
24-hour times on a timetable
Train and bus timetables show times like 16:45, and converting between 24-hour and 12-hour time is part of Level 5 measurement. When you're heading out, you can ask your child which service to catch and what its time would be on the kitchen clock.
The temperature graph in a weather app
Many weather apps show the temperature across a day or a week as a line graph. Reading a line graph that shows change over time is part of Level 5 statistics, so asking when it will be warmest, or how far it drops overnight, is a question about the graph your child can answer from the screen.
The rest of Level 5 maths, in plain words
- Factors and multiples, and whether one number divides evenly into another
- Percentages as part of a whole, linked to fractions and decimals, such as 50% being a half or 0.5
- Finding a missing number in a multiplication or division, such as
- Decimals with more than two decimal places, ordered on a number line
- Length, mass and capacity in metric units, and the perimeter (distance around) and area (space inside) of shapes
- Measuring and drawing angles in degrees with a protractor
- Nets: the flat shapes that fold up into a box or another solid
- Grid coordinates and directions to describe where something is and how it moves
- Sliding, flipping and turning shapes, and spotting symmetry
- Following and writing step-by-step instructions to explore patterns in numbers
- Collecting data, finding the most common value (the mode) and running chance experiments, like rolling a dice many times
Letting your child do the working out
You can try a few of these across a week, whenever one comes up.

The way your child has learnt at school may look different from the way you learnt, and Level 5 asks students to choose between mental and written methods, so there's often more than one sensible route to an answer. You don't need to know their method to follow it.
“How did you work that out?” can get them explaining. While they talk, you can notice whether they estimate before they calculate, which number facts they reach for and where they stop. When they pause, you can give them a moment rather than the next step, since deciding what to do next is part of the maths.
Who to tell about what you notice
When the same thing keeps coming up across a few weeks, like a fraction step that stalls each time or a set of facts your child still has to build every time, their classroom teacher is the person to tell. They can say whether it's something the class is still working on and what would help at home. You can also ask the school library which maths books or games your child can borrow.
If you'd like regular one-to-one practice alongside school, our primary maths tutors work in person across metropolitan Melbourne or online. You can bring a current task or teacher feedback, so sessions can focus on what your child is learning now.
Your next trip to the shops is a place to start: one question at the checkout, then listen.
Other questions about Year 5 maths
Is it okay for my child to use a calculator?
Yes, at times. Level 5 includes calculators and other digital tools where they suit the problem, alongside mental and written methods, and asks students to check that their answers are reasonable either way.
What if my child finds these too easy?
You can make the same moments harder by asking for the change before the total appears, tripling a recipe instead of doubling it, or planning a bigger shop against a budget.
What about Year 5 NAPLAN?
Year 5 students sit NAPLAN, which includes a numeracy test. ACARA, which runs NAPLAN, says students are not expected to study for it. Our guide to Year 5 NAPLAN explains the tests and the report.
When the report comes home, the NAPLAN results explained tool walks you through what each part means.
