Developing understanding of simple concepts (e.g. big/little).
Observe whether the child: developing understanding of simple concepts (e.g. big/little).
What it looks like
Three ways this behaviour shows up as a child grows. Each level includes everyday moments to watch for.
Emerging
Just starting
The child sometimes shows understanding of big/little with strong cues (pointing, exaggerated gesture) or in one familiar routine, but is inconsistent. They may use the words without matching the concept accurately.
What you might see
With a big spoon and a little spoon offered, when asked “Give me the big spoon,” the child hands either one without looking.
When asked “Where’s the little teddy?” the child grabs the nearest toy regardless of size.
When the adult points at the big cup and asks “Give me the big one,” the child chooses correctly, but chooses wrongly when the point is removed.
The child says “big!” for many items (including small ones) and does not adjust the label based on size.
Expected
On track
The child usually understands big/little when given two clear choices in familiar contexts (e.g., picking the big ball vs. little ball), sometimes needing the instruction repeated. They are beginning to use the words more accurately in play.
What you might see
With two cars (clearly different sizes), when asked “Show me the little car,” the child points correctly after a brief pause.
During tidy-up, when asked “Put the big blocks in the box,” the child sorts some correctly but mixes in a few small ones.
Exceeding
Going further
The child consistently understands and uses simple concepts like big/little across daily contexts without gesture support (books, play, getting dressed). They can follow instructions containing the concept and can identify the correct option among several.
What you might see
Among three toys, when asked “Find the biggest one,” the child selects the largest and then finds the smallest when asked next.
In a picture book, when asked “Which one is little?” the child points to the small object without the adult pointing first.
The child says “That one’s bigger” while choosing a larger container for toys, then switches to a smaller one for a small item.
When the adult mislabels (“This is the little ball” while holding the big ball), the child laughs or corrects with “No, big!”
Try this at home
Small everyday moments where you can notice this behaviour without setting up anything special.
Mealtime: put a big cup and a little cup on the table and ask “Which one is the little cup?” and notice whether your child points/chooses correctly without you pointing first.
Bath time: offer two towels (big and small) and say “Can you bring the big towel?” and watch whether your child selects the right one.
Play: use toy animals or cars in two sizes and ask “Where’s the little one?” then “Where’s the big one?” and notice consistency.
Story time: while looking at pictures with obvious size differences, ask “Which one is big?” and see if your child can answer across pages.
Getting dressed: show two items (big hat vs. tiny sock) and use big/little language naturally (“tiny sock”) and observe whether your child starts to use or respond to the concept.
Where this comes from
The framework source and supporting developmental research.
Framework source
DfE (2012). Development Matters in the Early Years Foundation Stage (EYFS).
Defines the age-banded progression for early understanding of basic concepts such as big/little.
Developmental research
Vygotsky, L. S. (1978). Mind in Society: The Development of Higher Psychological Processes. Harvard University Press.
Supports concept learning as developing through language-mediated interaction and guided comparison in everyday activities.

Not Yet
The child does not show understanding of simple contrasting concepts like big/little and responds randomly or only copies actions. They may not notice size differences when asked to choose.
With a big spoon and a little spoon offered, when asked “Give me the big spoon,” the child hands either one without looking.
When asked “Where’s the little teddy?” the child grabs the nearest toy regardless of size.

Secure
The child consistently understands and uses simple concepts like big/little across daily contexts without gesture support (books, play, getting dressed). They can follow instructions containing the concept and can identify the correct option among several.
Among three toys, when asked “Find the biggest one,” the child selects the largest and then finds the smallest when asked next.
In a picture book, when asked “Which one is little?” the child points to the small object without the adult pointing first.
Reflexive
The child applies the concept flexibly and can compare or explain (e.g., “this one big, that one little”), generalising to new objects and related contrasts (bigger/smaller). They may correct themselves or others during play.
The child says “That one’s bigger” while choosing a larger container for toys, then switches to a smaller one for a small item.
When the adult mislabels (“This is the little ball” while holding the big ball), the child laughs or corrects with “No, big!”
