Teaching Table

Set out your lesson

Predict how a flat net can form a triangular prism, then test if materials allow.

Activity

Comfort with the particular task and communication mode; optional oral/scribed work is recorded separately.

Policy

Check the learner can access these words/materials and prerequisite ideas; historical authorship is not readiness or mastery. If not, demonstrate briefly or revisit the named prerequisite.

Use the supplied measured net. Paper, ruler and optional adult-supervised scissors/tape are needed for physical folding; no-printer route is to draw the stated lengths. Do not claim a fold if only viewing. No printer: view only the active learner card on screen, or an adult copies its exact prompts onto plain paper without answers. Oral pointing/dictation is an access option; record it as adapted/supported and do not claim handwriting from it. Keep adult keys/scripts separate; supply only the current stage.

Use fictional cases and invented identifiers; never record personal conflicts, health, bank details or family spending. Adult prompts/keys are private companion files, never learner links.

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.

Physical folding and alternative-net identification remain conditional/partial. Supplied net is a new original diagram; browser/print dimensional fidelity is not yet tested.

Use fictional cases and invented identifiers; never record personal conflicts, health, bank details or family spending. Adult prompts/keys are private companion files, never learner links.

Check understanding

Identify which net will fold into a given 3-D shape
Construct the net of a triangular prism and fold it to verify
Describe a 3-D shape by naming its faces, edges, and vertices

“If your child is given a flat cross-shaped piece of card (a net), can they predict what 3-D shape it will make when folded up — and then fold it to check?”
