30–50 monthsNumerical PatternsShape, Space and Measure (no distinct 2021 ELG)
Beginning to talk about the shapes of everyday objects, e.g. ‘round’ and ‘tall’.
Observe whether the child: beginning to talk about the shapes of everyday objects, e.g. ‘round’ and ‘tall’.
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
Uses one or two everyday shape descriptors (e.g., “round,” “tall,” “long”) inconsistently, often copying an adult. Overgeneralises (e.g., calls many things “round”) or uses words without clear meaning.
What you might see
When asked “Which one is round?” cannot choose between a ball and a cube and looks to the adult for help.
Does not use any shape words during play even when an adult labels shapes (e.g., “round,” “tall”).
Describes objects only by colour or name (e.g., “red one,” “cup”) and not by shape.
Says “round” when an adult points to a ball, but then calls a cube “round” as well.
Repeats “tall” after an adult says it, without clearly linking it to the object’s shape/size.
Uses a single descriptor (“big”) for different shape ideas (round/long/tall).
Expected
On track
Describes the shapes of common objects using everyday language in familiar contexts (e.g., ball is round, bottle is tall). Begins to compare objects using simple shape descriptors with some accuracy.
What you might see
Says “The ball is round” during play and picks up the ball while saying it.
Describes a bottle or tower as “tall” and compares it to a shorter one after prompting.
Points to a plate/coin and says “round” without needing an adult cue.
Exceeding
Going further
Uses everyday shape talk spontaneously across contexts, linking objects to descriptors and noticing simple features (e.g., “pointy,” “corner,” “flat”). Uses descriptors mostly accurately even when objects vary in size or orientation.
What you might see
Describes different everyday objects using shape words (e.g., “round” for wheel, “long” for a stick) in the same play session.
Uses an additional informal feature word (e.g., “pointy,” “corner,” “flat”) when talking about an object.
Corrects their own description after checking (e.g., “It’s not round—it’s long”).
Explains a similarity (e.g., “The clock is round like the plate”) without being asked.
Begins to connect to formal names (e.g., “It’s round—like a circle”) while pointing at the object.
Helps a peer choose an object by descriptor (e.g., “Use the tall one for the tower, not the short one”).
Try this at home
Small everyday moments where you can notice this behaviour without setting up anything special.
Mealtime chat: During snack, ask, “Is this plate round or tall?” then “What else is round in our kitchen?” Notice whether your child uses shape words independently.
Bath time: Use cups/containers and ask, “Which one is tall? Which one is short?” Watch whether your child compares and uses the words meaningfully.
Outdoor hunt: On a walk, do a “shape hunt” for round things (wheels, manholes) and tall things (posts). Listen for your child’s own shape descriptions.
Story/picture talk: In a picture book, ask, “Which things are round? Which things are tall?” Notice whether your child explains or just points.
Toy sorting: Put out a ball, a box, a tube, and a flat book and ask, “Can you group the round ones together?” Watch for correct grouping and talk.

Not Yet
Does not describe the shapes of everyday objects and does not respond meaningfully to shape words like “round” or “tall.” Uses unrelated descriptors or relies on pointing only.
When asked “Which one is round?” cannot choose between a ball and a cube and looks to the adult for help.
Does not use any shape words during play even when an adult labels shapes (e.g., “round,” “tall”).
Describes objects only by colour or name (e.g., “red one,” “cup”) and not by shape.

Secure
Uses everyday shape talk spontaneously across contexts, linking objects to descriptors and noticing simple features (e.g., “pointy,” “corner,” “flat”). Uses descriptors mostly accurately even when objects vary in size or orientation.
Describes different everyday objects using shape words (e.g., “round” for wheel, “long” for a stick) in the same play session.

Corrects their own description after checking (e.g., “It’s not round—it’s long”).
Reflexive
Uses shape descriptors flexibly and begins to connect everyday words to more formal shape ideas (e.g., “round like a circle”). Explains similarities/differences in shape to peers and generalises across new objects.
Explains a similarity (e.g., “The clock is round like the plate”) without being asked.
Begins to connect to formal names (e.g., “It’s round—like a circle”) while pointing at the object.
Helps a peer choose an object by descriptor (e.g., “Use the tall one for the tower, not the short one”).
