Teaching Table

Set out your lesson

Round positive whole numbers to tens, hundreds and thousands and use rounded values to estimate.

Activity

Learner readiness not observed. Ask for the thousands and hundreds in 4,367. Revisit four-digit place value if either is unclear.

Policy

Check learner readiness separately; the existence of a prerequisite lesson is not evidence of attainment.

Estimated Minutes

20–30; split if useful

Sequence

Use S for the model, G for supported practice and T for a fresh attempt.
Optional pencil and scrap paper only. All scenarios, charts and blanks are supplied.
Put S, G and all adult keys away before T. Open only the T learner sheet.
Discuss the reasoning; use the adult key afterward and record only actual support and responses.

No Printer

No printer, purchases, cutting, login or installation required. Use one sheet on screen at a time; answer aloud or write only responses on scrap paper.

Safety

Pause if tired or frustrated. Fictional contexts need no personal information, travel, measuring equipment or real purchases. Participation is optional.

Access

Read prompts aloud without explaining answers; allow pointing, speech, zoom or adult scribing. Record adaptations separately from independent written evidence.

Record actual responses, assistance and access mode; 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.

No learner results or lesson efficacy have been established.
The canonical word “any” exceeds a short finite sample; coverage is partial. No negative-number rounding is assessed.

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

Check understanding

Round 4,367 to the nearest 10 (4,370), 100 (4,400), and 1000 (4,000)
Explain the rounding rule using a number line (which multiple is closer)
Apply rounding to estimate calculations

“Can your child round a number like 4,738 to the nearest 10 (4,740), 100 (4,700), or 1,000 (5,000) — and explain which digit they look at to decide?”
