Teaching Table

Set out your lesson

Practise the bounded task in Measuring & Plotting Lengths; see exact limits before inferring broader coverage.

Activity

Can read a centimetre ruler; measurements must be actual if described as observed.

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
Optional centimetre ruler and five paper strips; otherwise the explicitly labelled supplied practice data.

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.

Actual measurement conditional on equipment/performance; five objects rather than the source's ten-leaf assessment.

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

Measure the lengths of several objects and record the data
Create a line plot with a horizontal scale marked in whole-number units
Interpret a line plot to answer questions about the data

“If your child measures the length of ten leaves to the nearest cm and records the results, can they display the data on a simple number-line plot — grouping leaves of the same length?”
