Set out your lesson

Read minute marks and compare durations in a common unit.

Activity

Inferred, not a taxonomy edge: learner can access the supplied prompt with agreed support and can explain or mark a response. If earlier skills are unfamiliar, use the prerequisite topic for teaching; an authored prerequisite is not proof this learner is ready.

Sequence

Keep the two adult-only cards off the learner screen. Have a pencil and scrap paper if useful; oral pointing/typing/AAC can replace handwriting unless spelling or composition is the target. No printing, cutting, account or purchase is required.
Open Show first, read the explanation together, and pause to check the central idea. Then do Guided Try together.
For Try, close earlier models and the adult keys unless the task explicitly supplies a reference. Record any hints, read-aloud help or model reopening; do not call supported work independent.
Use only the active learner card. Keep the private key closed until an attempt is recorded. Stop or take a break on request; practical claims stay not observed unless actually done.

No Printer

Use on screen; read aloud or recreate a tactile model only with declared support. No printer or purchased kit.

Privacy

Never display adult keys or dictation spellings with a learner task; no family financial, identity or conflict disclosure.

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.

This lesson concerns estimating time. Actual timing requires a clock or timer.
These bounded examples do not establish independent performance in other situations. Record the support used.
Clock reading and given-time duration calculations are separate evidence components. Guided is supported; Try is a fresh finite opportunity only if prior models and adult keys are put aside. Verbal hand-position access is adapted evidence, not unaided visual reading.

Never display adult keys or dictation spellings with a learner task; no family financial, identity or conflict disclosure.

Check understanding

Read an analogue clock to the nearest minute
Estimate how long an activity takes in minutes or seconds
Compare two durations and determine which is longer

“If a TV show starts at 5:17 p.m. and ends at 5:43 p.m., can your child work out how long it lasted — and express that in minutes?”
