Writing numbers looks simple until you watch a five-year-old try: a 3 facing the wrong way, a 5 built from three separate bits, an 8 made of two stacked circles. That’s all normal. Here’s how to teach number formation from 0 to 9, with a short rhyme and a starting point for each number, why numbers get turned around, and a calm routine for practising at home.
When do children learn to write numbers?
Children start in their first year of school. In the Australian Curriculum, Foundation (Prep) children learn to “name, represent and order numbers including zero to at least 20, using physical and virtual materials and numerals” (AC9MFN01). One of its examples is “writing a numeral on a container as a label to show how many objects it contains”. The Victorian Curriculum 2.0 has the same goal for Prep (VC2MFN01), and in NSW, Kindergarten children read “numerals to at least 20, including zero”.
So the first year of school is when children learn to read and write numbers to 20. Expect those numbers to wobble, lean or face the wrong way now and then while they’re learning.
Why writing numbers is tricky
Tasmania’s Department of Education handwriting guidelines put it plainly: “Numerals are complex to write and learners will need plenty of practice to refine them and develop automaticity.” A few numbers need more than one direction in a single movement, and some look like mirror images of letters. Starting in the right place makes the biggest difference. For 5, the guidelines say to “emphasise correct starting point to prevent breakdown at speed”.
Number formation rhymes, 0 to 9
Rhymes are a home trick, not part of any curriculum, but they help children remember where to start and which way to go. These are our own, written to match how KidStudy’s Trace page draws each number in Victorian Modern Cursive. If your child’s school teaches a different start or order, follow the school.
| Number | Where to start | Say it as you write |
|---|---|---|
| 0 | Near the top, on the right | “Round we go, back to the start: zero.” |
| 1 | At the top | “Straight down we run, that makes one.” |
| 2 | Near the top, on the left | “Round the top, slide down, along the ground: two.” |
| 3 | Near the top, on the left | “Round to the middle, round again: three.” |
| 4 | At the top | “Down and across, lift, then down the middle: four.” |
| 5 | At the top, on the right | “A hat on top, down the neck, round the big tummy: five.” |
| 6 | At the top | “Curve down low and round the loop: six.” |
| 7 | At the top, on the left | “Across the sky and down the slope: seven.” |
| 8 | At the top, on the right | “Make an s, then climb back up: eight.” |
| 9 | At the top, on the right | “Round to make a ball, then down the stick: nine.” |
Notice that every number starts at or near the top. That’s the single most useful habit to build. A 5 is a good example: some styles put the hat on first, as KidStudy’s Trace page does, and others add it last, so check what your child’s class does.
A calm routine for practising numbers
- Watch it move. Tasmania’s guidelines list “teacher demonstration – that is, viewing a moving model” as a strategy. Write the number slowly while your child watches, saying the rhyme, or let them watch it on the Trace page.
- Go big first. Trace the number in the air, in a tray of sand, or with a finger on the table. Big movements help the shape stick.
- Trace on paper. Use a sheet with a start dot and dotted numbers, starting at the dot each time.
- Copy from a model. Put a written model beside your child, on the table, so they can look across at it while they write.
- Use it for real. Label containers with how many things are inside, write the date, number the pages of a little book, or keep score in a game.
Five minutes is plenty. One or two numbers a day, done well, beats a whole row done in a hurry.
Why does my child write numbers backwards?
Turning numbers and letters around is very common while children are learning to write. The official guidance we found talks about letters rather than numbers, but the same ideas apply. Tasmania’s guidelines say: “Letter reversals are a normal occurrence for some children between the ages of five and eight ... Given time and adequate support they generally self-correct.”
Numbers face one way or the other, and to a young child the direction can seem not to matter much: a toy car is still a car whichever way it points. What helps most is the same thing that helps with letters:
- The right starting point, every time. When the start is fixed, the direction usually follows.
- The movement, said out loud. The rhyme gives your child words for which way to go.
- A model to check against. A number line on the wall or the fridge lets your child check for themselves.
- Gentle correction. Point to the model and say “Let’s start at the dot” rather than “That’s wrong”.
Our post on why children write letters backwards explains more, including the b and d mix-up.
How big should numbers be?
Different styles answer this differently. Tasmania’s guidelines say: “In handwriting, numerals are often shorter – about the height of a lower case ‘t’”, and that “the relative size of numerals and letters is less important than the accurate, efficient and legible formation.” All numerals “are written with a slight slope and sit on the line” in the Tasmanian style. Follow your child’s school for size; what matters most is that each number sits on the line and is easy to read.
When to ask for help
Most children sort out their numbers with time and a little practice. The Raising Children Network lists “writing in a messy way – this might look like reversed letters, letters not correctly closed, inconsistent letter size” among the early signs of handwriting difficulty. If you notice several of these together, or your child is upset by writing, it suggests talking “with your child’s preschool or school teacher or your GP”. You don’t need a GP referral to see an occupational therapist. If pencil control seems to be the problem, our guide to pencil grip by age shows what’s typical.

Questions parents ask
How do I teach my child to write numbers?
Show one number at a time, slowly, starting at the top and saying the movement out loud. Let your child trace it big, then trace a dotted number from a start dot, then copy it beside a model. A few minutes a day is plenty.
What are number formation rhymes?
Short sayings that describe how to write each number, such as “Straight down we run, that makes one”. They’re a home and classroom trick for remembering where to start and which way to go, not part of the curriculum.
Is it normal for a 5-year-old to write numbers backwards?
Yes, it’s very common. Official guidance describes letter reversals as normal for some children between five and eight, and numbers get turned around for the same reasons. A fixed starting point and a model to check against help most.
When should my child be able to write numbers to 20?
Children work on this in their first year of school. In the Australian Curriculum, Foundation children learn to name, represent and order numbers to at least 20, including writing numerals, for example to label how many things are in a container.
Should numbers be as tall as capital letters?
It depends on the handwriting style. Tasmania’s guidelines say handwritten numerals are often about the height of a lower-case t, and that clear, efficient formation matters more than exact size. Follow your child’s school.
When should I worry about number reversals?
Reversals are common up to about age eight and usually fade with practice. If they’re frequent alongside other handwriting difficulties, or writing upsets your child, talk to the teacher or your GP.
