Year 4 Maths in Australia: What Your Child Learns

Year 4 is the year maths starts to feel "bigger." Numbers stretch past 10,000, multiplication and division become everyday tools, and fractions step beyond simple halves and quarters. It can look like a big jump from Year 3 — but it is really the same ideas, used with more confidence.

This guide explains what your child learns in Year 4 maths under the Australian Curriculum, the skills to watch for, where children commonly get stuck, and simple ways you can help at home. No jargon, no curriculum codes — just a clear picture. Browse and download free Year 4 maths worksheets here.

What your child learns in Year 4

Australian maths is organised into six areas. Here is what each one looks like in Year 4.

Number

Children read, write and order numbers beyond 10,000, and begin working with simple fractions and decimals. They recall multiplication facts up to 10 × 10 and use them to multiply and divide larger numbers.

Algebra

This is the start of "thinking like a mathematician" — spotting and continuing number patterns, and understanding that addition and multiplication can be done in any order.

Measurement

Students measure length, mass, capacity and temperature using proper units (centimetres, grams, litres), tell time to the minute, and work with am/pm and calendars.

Space

Children describe and compare 2D shapes and 3D objects, learn about angles, and use simple maps, grids and directions.

Statistics

Students collect data and show it in tables and graphs — and, importantly, begin to *interpret* what a graph is telling them.

Probability

Year 4 introduces the language of chance — describing how likely an everyday event is, and ordering outcomes from "impossible" to "certain".

💡 Parent tip: Knowing the names just helps you follow your child's school reports and ask better questions — "What are you doing in measurement at the moment?"

What is new compared to Year 3

Most of Year 4 builds directly on Year 3 — here is what actually steps up.

Real-life maths in Year 4

Maths in Year 4 shows up all over the house:

• Fractions when sharing a pizza or cutting a cake into equal pieces.
• Multiplication when working out how many cupcakes are in 6 boxes of 8.
• Measurement when following a recipe or checking how much someone has grown.
• Money when counting change or comparing prices at the shops.

Pointing these out turns everyday moments into quiet practice — no worksheet required.

Skills to look for by the end of Year 4

By the end of the year, most students can:

• Read, write and order numbers beyond 10,000
• Recall multiplication facts up to 10 × 10
• Multiply and divide two- and three-digit numbers
• Compare and count by simple fractions
• Tell time to the minute and use am/pm
• Read and interpret simple graphs and tables
• Describe the chance of everyday events

If a few of these feel shaky near the end of the year, that is useful to know — it points to where a little extra practice helps. It is a guide, not a pass-or-fail test.

Where Year 4 students often struggle

A few sticking points are very common — and completely normal.

• Times tables. Multiplication and division both rely on quick recall. Children who have not locked in their tables find much of Year 4 maths slow and tiring.
• Fractions becoming abstract. A fraction stops being "a slice of pizza" and becomes a number in its own right. That shift confuses many children.
• Multi-step word problems. Knowing *which* operation to use is often harder than the calculation itself.

💡 Parent tip: If your child is finding Year 4 maths hard, check the times tables first. Shaky recall is the single most common cause.

How you can help at home

You do not need to be "good at maths" to help. Small and regular beats long and stressful.

• Times-table practice — five minutes a day, in the car or at dinner.
• Cook together — halving and doubling a recipe is real fraction work.
• Shop together — let your child estimate the total and count the change.
• Play games — dice and card games quietly build number sense.
• Talk through mistakes — ask "how did you get that?" rather than just marking it wrong.

Try a few Year 4 questions

See how your child goes with these:

1. What is 7 × 8?
2. Which is larger: ¾ or ½?
3. A box holds 6 pencils. How many pencils are in 9 boxes?
4. What is 4,250 + 1,300?

Does this change by state?

Mostly, no. Year 4 maths is very similar across Australia — Western Australia, Queensland, South Australia, Tasmania, the NT and the ACT all follow the national curriculum closely. New South Wales and Victoria use their own versions, but the Year 4 content is broadly the same. The topics above are a reliable picture wherever you live.

Year 4 is a confidence year. Lock in the times tables, keep fractions hands-on, and most of the rest falls into place.
