Name the eight planets in order from the Sun (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune), know that Pluto is a dwarf planet, and distinguish rocky inner planets from gas giant outer planets

Lesson

Set out your lesson

Practise the bounded task in The Eight Planets; see exact limits before inferring broader coverage.

Before teaching

Use this short check, then start teaching.

Activity

Can rehearse an ordered sequence; sizes and distances are not represented by spacing.

Policy

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

Printer, credit, and teaching notes

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.

Check understanding

List all eight planets in order from the Sun
State that Pluto was reclassified as a dwarf planet in 2006
Explain that the four inner planets are small and rocky while the four outer planets are large gas giants

“Can your child list all eight planets in order from the Sun — maybe using a memory trick like 'My Very Eager Mother Just Served Us Nachos'?”
