Teaching Table

Set out your lesson

Explain seven dietary components without treating food as one nutrient or prescribing a diet.

Activity

Follow this model in an accessible mode before attempting independent work. Graph ordering is not learner mastery; revisit prerequisites if the guided task still needs full modeling.

Policy

Check readiness rather than assuming source graph order establishes attainment.

Use fictional foods only. No tasting, food weighing, calorie targets or personal meal disclosure. Respect allergies, access, culture and disability. Open Show (S), then Guided (G), then Try (T). Hide earlier work and keys before Try. Use only the supplied stage material; do not invent additional cards. Pause or split the session if needed.

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.
