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
Full guide and materials
- 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
- Step 1. Before the child joins, make the large physical pyramid. Use the ruler and pencil to draw an 8 cm square on cereal-box cardboard. Mark the midpoint of each side, measure 8 cm straight outward perpendicular to the side from each midpoint, and mark an apex. Connect each apex to that side’s two corners to make four congruent isosceles triangles. Cut around the outside, lightly score or crease the four square edges, fold the triangles up, tape adjoining edges, and put the scissors away.
- Step 2. Place the ball, adult-handled can, large cube object, non-cube rectangular box or book, cone object, and physical pyramid model where your child can see them. The adult keeps control of the can.
- Step 3. Name sphere, cylinder, cube, cuboid, cone, and pyramid together while pointing to each matching object or model.
- Step 4. Mix the positions and ask your child to find each named 3-D shape. Compare cube with cuboid and cone with pyramid so the similar-looking pairs stay distinct.
- Step 5. Ask for an environment match: ball–sphere, can–cylinder, large block–cube, book or box–cuboid, and party hat–cone. Then ask your child to identify the physical pyramid model among all six solids.
- Quick check. Reorder the six physical items. Success means your child names the cube, sphere, cylinder, cone, cuboid, and pyramid; matches the five household objects to their 3-D shape names; and picks the physical pyramid model from the mixed set of solids.
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.

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)?”
