Shows interest in shape by sustained construction activity or by talking about shapes or arrangements.
Observe whether the child: shows interest in shape by sustained construction activity or by talking about shapes or arrangements.
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
Shows brief interest in building or arranging, and may notice a shape feature occasionally, usually after an adult prompt. Comments about shapes/arrangements are occasional and not sustained.
What you might see
During block play, stacks one or two pieces and walks away without trying to align edges or balance a structure.
When an adult says “Let’s make a square/triangle,” picks any piece without looking and does not comment on the choice.
Does not use or repeat any shape/arrangement words (e.g., “round,” “corner,” “side,” “next to”) even after an adult models them.
Builds for a short time, then stops; after an adult prompt, rotates a piece once to try to make it fit.
Points to a shape or arrangement and says a single descriptor (e.g., “round”) but does not continue the talk.
Notices when a structure won’t work (“It fell”) but needs adult help to decide what to change.
Expected
On track
Sustains shape-related construction or arrangement in familiar play, sometimes describing what they are making and how pieces go together. Uses simple shape or arrangement language with support.
What you might see
Builds a simple bridge/house for several minutes and says where pieces go (e.g., “on top,” “in the middle”).
Chooses a flatter piece for a base/floor after a reminder and says “this one goes under.”
Talks about what they made using a shape idea with support (e.g., “triangle roof” after an adult models the phrase).
Exceeding
Going further
Regularly sustains construction/arrangement play and independently talks about shapes or how items are arranged to make a structure or pattern. Adjusts choices to make pieces fit and can describe what they changed.
What you might see
Sustains construction play and revises it to make it steadier (adds a wider base) without adult prompting.
Says a shape/arrangement idea spontaneously (e.g., “two squares next to each other,” “a line,” “a circle”).
Searches for a piece by property (e.g., “I need a long one”) and uses it to solve a fit/stability problem.
Describes a plan before building (e.g., “We need four sides and a roof”) and follows through with adjustments.
Generalises shape talk to the environment during play (e.g., “wheels are circles like this”) without prompting.
Helps a peer by describing orientation/fit (e.g., “turn it so the flat side matches, then it will fit”).
Try this at home
Small everyday moments where you can notice this behaviour without setting up anything special.
Construction play: Offer blocks/LEGO and say, “Can you build a home/garage?” Notice whether your child sustains the build and talks about shapes or how pieces are arranged.
Out and about: On a walk, point to windows/tiles and ask, “What shapes can you see? How are they arranged?” Listen for shape words or arrangement talk (rows, lines, next to).
Mealtime patterning: Arrange snacks (e.g., cracker–grape–cracker) and ask your child to copy and tell you what the pattern is. Notice whether they describe the arrangement.
Story time: During a picture book, ask, “Where are the shapes in this picture?” Notice whether your child talks about how parts fit together (roof on top, wheels underneath).
Bath/foam shapes: Provide foam shapes and say, “Can you make a boat/house on the tiles?” Watch for sustained arranging and any shape/space language.

Not Yet
Does not choose shape-based construction play and does not comment on shapes or arrangements, even when an adult models or prompts. Builds or places items without attending to how pieces fit together.

When an adult says “Let’s make a square/triangle,” picks any piece without looking and does not comment on the choice.
Does not use or repeat any shape/arrangement words (e.g., “round,” “corner,” “side,” “next to”) even after an adult models them.

Secure
Regularly sustains construction/arrangement play and independently talks about shapes or how items are arranged to make a structure or pattern. Adjusts choices to make pieces fit and can describe what they changed.
Sustains construction play and revises it to make it steadier (adds a wider base) without adult prompting.

Searches for a piece by property (e.g., “I need a long one”) and uses it to solve a fit/stability problem.
Reflexive
Plans and adapts constructions flexibly, generalising shape ideas across contexts and explaining decisions using shape/arrangement language. Can guide peers by describing how to orient or choose pieces to fit.
Describes a plan before building (e.g., “We need four sides and a roof”) and follows through with adjustments.
Generalises shape talk to the environment during play (e.g., “wheels are circles like this”) without prompting.
Helps a peer by describing orientation/fit (e.g., “turn it so the flat side matches, then it will fit”).
