Teaching Table

Set out your lesson

Practise the bounded task in Patterns & Codes for Information; see exact limits before inferring broader coverage.

Activity

Copy short patterns and agree on a shared meaning.

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.

Real Morse/semaphore systems not taught; partner communication conditional, no device, flashing light or security claim.

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.

Check understanding

Describe at least two systems that use patterns of light or sound to transfer information (e.g. Morse code, semaphore, drum signals)
Design a simple code using light or sound patterns to send a message
Compare the advantages and disadvantages of different information transfer methods

“Can your child come up with different ways to send a secret message using patterns of light or sound, like Morse code or drum beats?”
