What it is

Subitise: To recognise a small number of things at a glance, without counting them one by one. You do it every time you read the spots on a dice.
Conceptual subitising: Seeing a bigger number as smaller groups you can each subitise: "three here and three here, so there must be six".
Composition of a number: The smaller numbers that make it up. 5 is made of 4 and 1, or 3 and 2.
Five frame and ten frame: A row of 5 boxes, or two rows of 5, that counters go in. They make small numbers easy to see at a glance.

Subitising isn't a trick or a speed test. It shows your child has a picture of what "three" or "four" looks like, which is the start of really understanding numbers rather than just saying them in order.

Counting is still important. For bigger groups, your child needs to count accurately: one number word for each object, and knowing that the last number they say tells them how many there are altogether.

Subitising also leads into early adding. A child who can see 4 dots as 2 and 2, or 5 as 4 and 1, is already noticing the parts inside a number. Those parts are the start of number bonds.

How it's taught at school

The EYFS statutory framework sets out early learning goals: the level children are expected to reach by the end of Reception. The maths goal for number says children will:

have a deep understanding of numbers to 10, including how each number is made up
subitise (recognise quantities without counting) up to 5
automatically recall number bonds up to 5, and some number bonds to 10, including doubles

Development Matters, the DfE's non-statutory guidance for early years, describes ways to build this up. Before Reception, 3 and 4-year-olds start with fast recognition of up to 3 objects. In Reception, the guidance suggests showing small numbers in familiar patterns, like dice, and in random arrangements too.

It also suggests games where objects are quickly shown and then hidden, putting counters into five frames and then ten frames, and asking children to show a number of fingers all at once without counting. With groups of up to 4 or 5, children are encouraged to subitise first and then count to check.

Your child will also link numbers to their written numerals, for example matching the numeral 4 to a card with 4 dots. Development Matters suggests card games such as snap or matching pairs for this.

In the summer term of Reception, by 30 June, your child's teacher completes the EYFS Profile. This isn't a test: the teacher makes an overall judgement about each early learning goal from what they have seen your child do during the year.

Tip
Ask "How did you know?" after your child answers. Hearing "because it's 2 and 2" tells you they are subitising, not guessing, and it helps them notice the parts inside a number.

Common mistakes (and how to help)

Counting every object one by one, even in a group of 3: That's fine, and counting is a skill they need. Try the guidance's approach: "I don't think we need to count those. They're in a square shape, so there must be 4." Then count together to check.
Recognising dice patterns but not the same number arranged differently: Mix it up. Put 3 buttons in a line, then in a triangle, then scattered. Ask "Is it still 3?" each time, so your child learns that the number stays the same however the objects are arranged.
Losing track when counting a bigger group, or counting the same thing twice: Move each object across as it's counted, or touch each one. Then ask "So how many are there?" and praise the last number. It shows the last number said is the total.
Seeing 4 dots but not linking them to the numeral 4: Play matching games with dots and numerals. Write the numerals 1 to 5 on scraps of paper and ask your child to put the right number of objects next to each one.

Three quick activities at home

Peek and hide

About 5 minutes · You need: A tea towel and up to 5 small things, such as pasta pieces or toy cars

Under the tea towel, set out between 1 and 5 objects.
Lift the tea towel for about two seconds, then cover them again.
Ask your child how many they saw, and how they knew. Lift the towel and count together to check.
Take turns, so your child hides some for you.

Finger flash

About 3 minutes · You need: Nothing: this works well in a queue or on a walk

Say a number up to 5, and ask your child to show that many fingers all at once, without counting them up one by one.
Now you flash some fingers, and your child says how many.
For a challenge, use two hands, such as 3 and 2, and ask how many altogether.

Spot snap

About 10 minutes · You need: A pack of playing cards, using only the aces to 5s

Shuffle the cards and split them between you.
Take turns to turn a card over onto a pile. Your child says how many spots are in the middle of the card, without counting if they can. An ace has 1.
When two cards in a row have the same number, the first to say "snap" wins the pile.

Questions parents ask

Will my child be tested on subitising?

Not with a test. Subitising up to 5 is part of an early learning goal, and your child's teacher decides whether your child has met it from what they see in class during Reception. The school must share the results of the EYFS Profile with you, and explain when you can talk them through with the teacher.

My child always counts instead. Is that a problem?

No. Counting is an important skill in its own right. Subitising develops with lots of quick looks at small groups, so keep the games light and let your child count to check whenever they want to.

Should I teach subitising beyond 5?

The early learning goal stops at 5. For bigger numbers, help your child see them as groups they know, such as 6 as 3 and 3. That's the start of conceptual subitising.
