2-D faces on 3-D shapes
Identify 2-D shapes on the surface of 3-D shapes (e.g. a circle on a cylinder, a triangle on a pyramid)

Teaching Table
Set out your lesson
Identify flat circular and triangular faces on solids and distinguish curved surfaces.
Recognise circle, triangle and square as flat shapes; handle safe solid objects or use the supplied diagrams.
Directed source edges are preserved, not assumed completed. If the readiness probe is difficult, model with support and record supported practice instead of independent evidence.
Use the supplied stage-specific structured materials. Plain paper and pencil; screen viewing is optional.
Show, guided, put teaching sheet aside, then task sheets in order; adult keys remain private.
No printing or cutting is required unless explicitly choosing a physical construction. Exact paper alternatives are in each material; adaptations change the evidence mode as stated.
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: Identify 2-D shapes on the surface of 3-D shapes (e.g. a circle on a cylinder, a triangle on a pyramid)
Source assessment's rectangle-wrapped-side wording clarified: unwrapped surface versus flat face. Real handling conditional; perspective descriptors may supply face identity and are not equivalent visual evidence. This is a bounded task opportunity, not established attainment or automatic use across contexts.
- partial: Point out a circular face on a cylinder or cone
Mapped task(s) offer this clause only within the supplied examples. Source assessment's rectangle-wrapped-side wording clarified: unwrapped surface versus flat face. Real handling conditional; perspective descriptors may supply face identity and are not equivalent visual evidence. No attainment or automatic/general performance is claimed.
- partial: Identify triangular faces on a pyramid
Mapped task(s) offer this clause only within the supplied examples. Source assessment's rectangle-wrapped-side wording clarified: unwrapped surface versus flat face. Real handling conditional; perspective descriptors may supply face identity and are not equivalent visual evidence. No attainment or automatic/general performance is claimed.
- partial: Recognise that the faces of 3-D shapes are 2-D shapes
Mapped task(s) offer this clause only within the supplied examples. Source assessment's rectangle-wrapped-side wording clarified: unwrapped surface versus flat face. Real handling conditional; perspective descriptors may supply face identity and are not equivalent visual evidence. No attainment or automatic/general performance is claimed.
- partial: Can {{name}} look at a 3-D shape and name the 2-D shapes on its faces — for example, saying a cylinder has circles on the ends and a rectangle wrapped round the side?
