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.

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 2026-11-12 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)?”
