Subitising to 5
Recognise and name the number of objects in a collection of up to 5 instantly, without counting one by one (subitising), using dot patterns, dice faces, fingers and small groups of objects
Lesson
Set out your lesson
“Subitising to 5 means knowing how many at a glance up to 5—dice faces, fingers, small piles—without counting one by one. We will flash patterns, name amounts, then check a fresh flash.”
Bring to the table
- Dice or dot cards 1–5
- 5 large counters (parent keeps tiny pieces away from mouths)
Extra for the adult
Worked example. A standard dice 5 can be named at a glance as five without counting each pip.
Optional challenge. For Subitising to 5, flash two groups and say which is more without counting. Optional: child flashes cards for you.
What to notice. Keep one parent note: patterns; glance vs count; support used. This session samples subitising, not mastery of every pattern to 5.

Subitising to 5 means knowing how many at a glance up to 5—dice faces, fingers, small piles—without counting one by one. We will flash patterns, name amounts, then check a fresh flash.
Spend about 10 minutes subitising collections to 5 with quick flashes, then checking a new pattern.

Public Illustrative Mathematics task page. The .html address responds HTTP 308 to this URL. An anonymous GET of this URL on 2026-11-12 returned HTTP 200 with no login or payment prompt. Where a teacher solution is present, it is on the same page as the student task; this check did not find a separate locked student view. An adult can use the student view section and should not read a solution aloud. Advertising was not observed in the fetched HTML text; that is not a browser, device, or ad-free guarantee. This is a paper or discussion task, not an automatically marked interactive game. Opening the link does not save practice or assess mastery. Diagrams on the page use missing or filename-only alt text, so they are not an accessible image equivalent. Accessibility still depends on an adult describing the picture.

Check understanding
- Say how many dots are on a dice face showing 4 after a one-second glimpse, without counting
- Show 3 fingers quickly without counting them up one at a time
- Name the number in a flashed group of 2 or 5 counters arranged in different layouts
“When your child rolls a dice in a board game, can they say how many dots there are straight away — without counting each dot?”
