Classification Keys

Explore and use classification keys to identify, group, and name living things in local and wider environments

Lesson

Set out your lesson

Practise the bounded task in Classification Keys; see exact limits before inferring broader coverage.

Before teaching

Use this short check, then start teaching.

Activity

Follow yes/no instructions using visible traits.

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

Follow a branching classification key to identify an unknown organism
Create a simple yes/no classification key for a set of 6-8 organisms
Use a key to identify organisms in the local environment during a field activity

“Can your child use a simple yes/no key chart to work out the name of an insect or plant they've found outside?”
