Teaching Table

Set out your lesson

Practise the bounded task in How fossils form; see exact limits before inferring broader coverage.

Activity

Use above/below and earlier/later.

Policy

Exact directed source edges retained; earlier authorship is not learner attainment.

Materials

These supplied stage cards
Scrap paper and pencil; oral/pointing response where appropriate

Sequence

Read readiness and decide on support without treating prerequisite authoring as learner readiness.
Open Show first and explain its model.
Use Guided Try with support and its separate adult key.
Close Show and guided keys before Try, unless this Try is explicitly supported.
Reflect on an actual attempt, including help used.

No Printer

Use the supplied screen cards; copying the exact task to paper is optional, not required.

Privacy

Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

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.

Paper inference only; no field observation, dating technique or universal layer rule verified.

Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

The teaching approach appears above.

Check understanding

Explain that rock layers (strata) form over time, with the oldest at the bottom
Describe how fossils in different layers provide evidence of organisms that lived at different times
Use patterns in rock formations to explain how a landscape has changed over millions of years

“If your child sees layers of rock in a cliff face, can they explain that the bottom layers are oldest and any fossils tell us what lived there long ago?”
