Teaching Table

Set out your lesson

Use proportional reasoning to estimate miles and kilometres in both directions.

Activity

Check mt_p6MhZJYYPN and equivalent-ratio reasoning. A source record alone does not prove either skill.

Policy

Check learner readiness directly; prerequisite availability is not attainment.

Materials

Pencil and plain paper, or this screen and an oral explanation. No purchases, food, scissors, weighing or real journey needed.

Procedure

Choose one short sitting or stop after Together and return later. Read the model aloud, invite the learner to try, then put Show and Together aside for Try. Keep adult keys closed and out of view.

Access

No printer: show only the active learner sheet; copy the supplied grid/table or draw on plain paper. An adult may read exact prompts or scribe the learner’s own words without adding a method; record that support. Oral work is mathematical evidence, not handwriting evidence.

Privacy

Use fictional quantities. No names, addresses, body measurements, accounts, family records or purchases are required. A learner can pause or decline a context.

Teaching Procedure

Ask what stays the same, which unit is being counted, and what operation fits. Let the learner explain before helping. If stuck, return to the worked model, then retry; record the help rather than calling it independent.

Use fictional quantities. No names, addresses, body measurements, accounts, family records or purchases are required. A learner can pause or decline a context.

Record actual responses, access mode and assistance; never invent observations or infer mastery.

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.

Finite task opportunities do not establish general mastery. Exact canonical examples are rehearsal when previously modeled. No timed testing or forced personal disclosure.

Convert 40 miles to approximately 64 km
Explain why the conversion factor between miles and km is approximately 1.6
Use the miles↔km relationship to compare a 10 km race with a 6-mile run

“If your child is driving 40 miles to a theme park, can they use the rule that 5 miles ≈ 8 km to estimate roughly how many kilometres that is?”
