Recognising and drawing shapes by attributes

Recognise and draw shapes having specified attributes (e.g. a given number of angles or equal faces); identify triangles, quadrilaterals, pentagons, hexagons, and cubes

Lesson

Set out your lesson

Classify polygons by sides and angles, not appearance.

Before teaching

Activity

Ask the learner to explain one prerequisite idea before starting. If uncertain, revisit it; graph order is not learner readiness.

Policy

Check readiness rather than assuming source graph order establishes attainment.

Printer, credit, and teaching notes

Instructions

Use polygon SVG and scrap paper. Do not infer that this title requires triangle angle sums; the canonical contract asks shape attributes.

No Printer

Use the supplied stage cards on screen or scrap paper; adult key stays separate.

Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.

What this lesson covers and its limits

These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.

partial: Recognise and draw shapes having specified attributes (e.g. a given number of angles or equal faces); identify triangles, quadrilaterals, pentagons, hexagons, and cubes
Bounded objective: Classify polygons by sides and angles, not appearance. Polygon subset only; cube/equal-face part of description not assessed here.
partial: Draw a shape with exactly 5 sides (pentagon)
Five-sided drawing opportunity with simple closed-boundary criterion.
partial: Identify all quadrilaterals in a set of mixed shapes
Quadrilaterals identified from supplied outlines, finite set only.
partial: Name and draw a hexagon, explaining it has 6 sides and 6 angles
Hexagon drawing plus six-side/six-angle explanation required.
partial: If {{name}} is given instructions like "draw a shape with 5 sides" or "draw a shape with all equal angles," can they draw it correctly?
Try offers new-visual-and-drawing-application for the bounded objective; it does not establish every part of the source assessment. Polygon subset only; cube/equal-face part of description not assessed here.

Before you open · source notes

Shapes are sorted and drawn by side and angle attributes of polygons. Use it to name defining attributes, not every 3-D solid.

Free, no sign-in. A teacher solution is on the same page, so use the student view with your child.

Before you open

Ask the learner to draw or point to a polygon and say how many sides it has. Naming one shape does not cover every polygon family.

Source, access and review notes

Public Illustrative Mathematics task page. The .html address responds HTTP 308 to this URL. An anonymous GET of this URL on 2026-11-11 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.
