Teaching Table
Set out your lesson
Identify solid shapes from nets and line drawings while checking hidden structure.
Ask for an example of one prerequisite idea; revisit if needed. Historical graph coverage does not establish this learner’s readiness.
Use actual net and wireframe coordinate data; small SVGs supplied. No cutting needed. An optional paper cube net can be folded only after drawing/copying; screen measurements are not calibrated.
Use supplied stage sheets on screen or scrap paper; keep adult keys separate.
Use the fictional scenarios. Passing is allowed. Do not ask for private money amounts, account details, family conflict, identity or health information. Keep only minimal local learning notes.
Supplied data are explicitly practice data, not observations. Record only what is actually attempted; absent equipment, consent, partner or repeated observations means that part remains pending.
Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view. Retain an earlier model only when the current step supplies it as context.
Teaching limits and safe use
These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.
Bounded nets/wireframes; one perspective drawing, not comprehensive isometric interpretation or actual folded-object evidence.

Check understanding
- Identify a cuboid from its net
- Name the 3-D shape shown in an isometric drawing
- Match 2-D representations to the correct 3-D shape
“If you show your child a flat architect's sketch of a box or a pyramid, can they tell you the name of the 3-D shape it represents?”
