3-D shapes
Recognise and name common 3-D shapes (cubes, cuboids, pyramids, spheres, cylinders, cones)
Lesson
Set out your lesson
“A 3-D or solid shape has length, width, and height. A sphere is shaped like a ball. A cylinder is shaped like an unopened can. A cone has one circular base and narrows to a point. A cube has six equal square faces and is a special cuboid. A non-cube cuboid has six rectangular faces that are not all equal and can look like a book or box. A square-based pyramid has one square base and four triangular faces meeting at a point.”
Bring to the table
- Ball or orange for a sphere
- Adult-handled unopened food can for a cylinder
- Large cube-shaped box or block too large to fit in the child’s mouth
- Book or non-cube rectangular box for a cuboid
- Party hat or paper rolled by the parent for a cone
- Large physical square-based pyramid model prepared by the adult from cereal-box cardboard and tape
- Ruler or measuring tape
- Pencil or marker
- Adult scissors used only before the child joins
Extra for the adult
Worked example. A ball is a sphere because it is round in every direction. An unopened can is a cylinder because it has two flat circular ends and one curved surface. A cone has one circular base and one point; a square-based pyramid has triangular faces meeting at a point.
Optional challenge. Sort the shapes by whether they can roll, stack, or do both, then explain why a cylinder can roll on its curved surface and stack on a flat face.
What to notice. Save a short parent note recording correct identifications of cube, sphere, cylinder, cone, cuboid, and the physical pyramid model plus at least four object-to-shape matches. A photo may show the objects only. Use no small loose pieces or choking hazards; the adult handles the unopened can.

Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
A 3-D or solid shape has length, width, and height. A sphere is shaped like a ball. A cylinder is shaped like an unopened can. A cone has one circular base and narrows to a point. A cube has six equal square faces and is a special cuboid. A non-cube cuboid has six rectangular faces that are not all equal and can look like a book or box. A square-based pyramid has one square base and four triangular faces meeting at a point.
Spend 10–12 minutes naming the six supplied solid shapes, matching five of them to safe household objects, and recognising the pyramid among the set.

Shape Hunt Part 2
Before you open · source notes
A second shape hunt supports noticing 3-D shapes around the room. Not every net-folding project.
Free, no sign-in. A teacher solution is on the same page, so use the student view with your child.
Before you openAsk the learner to find two 3-D shapes and name them.

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
- Name a cube, sphere, cylinder, and cone when shown them
- Identify 3-D shapes in the environment (e.g. a tin is a cylinder)
- Recognise a cuboid and a pyramid among a set of solid shapes
“Can your child name common 3-D shapes they find around them — like a tin of beans (cylinder), a ball (sphere), or a dice (cube)?”
