## Title

A three-digit gallery

## Time

15–30 adjustable minutes or several short offers; optional project, not required homework.

## Purpose

Make something a willing reader could actually use: a replayable paper route guide or a complete quantity/order card with a checking reason.

## Complete launch source

Fictional quantity cards: Maker-label cards. First 105 labels; second 150 labels; third 501 labels. Each number counts the same kind of label, not prices or observed stock. A hundred has the value of ten tens; a ten has the value of ten ones. Represent whole quantities, compare their places and explain an order.

## Launch invitation

Make a useful quantity guide: show each whole value, choose an order and explain a check. Keep zero places labelled.

## Own first

- Choose one job and explain who might use the guide. A fictional reader or solo rehearsal is fine.

- Receive own source-specific route or representation before adult worked support.

- Build/dictate a complete guide with a legend, full quantities or directions and one checking reason.

- Use the stated source to replay/check. If a willing real reader tries it, record their actual words/actions with permission; otherwise keep it as a proposed test.

- Change one explained feature and keep both chosen versions manually. Recheck the full source after any change.

## After own model

105 = 1 hundred + 0 tens + 5 ones = 100 + 0 + 5. 150 = 1 hundred + 5 tens + 0 ones = 100 + 50 + 0. 501 = 5 hundreds + 0 tens + 1 one = 500 + 0 + 1. Least to greatest: 105, 150, 501. Compare from the highest differing place; a last digit alone cannot override an earlier place.

## Complete different guided source

Fictional quantity cards: Maker-label cards — separate later cards. First 206 labels; second 260 labels; third 602 labels. Each number counts the same kind of label, not prices or observed stock. A hundred has the value of ten tens; a ten has the value of ten ones. Represent whole quantities, compare their places and explain an order.

## Guided offer

Make a useful quantity guide: show each whole value, choose an order and explain a check. Keep zero places labelled.

## Guided staff possible

206 = 2 hundreds + 0 tens + 6 ones = 200 + 0 + 6. 260 = 2 hundreds + 6 tens + 0 ones = 200 + 60 + 0. 602 = 6 hundreds + 0 tens + 2 ones = 600 + 0 + 2. Least to greatest: 206, 260, 602. Compare from the highest differing place; a last digit alone cannot override an earlier place.

## Make it yours

- Swap the story purpose while preserving source quantities/positions, or declare/recheck a complete new source.

- Use marks, oral directions, sign/AAC or a tactile model. No polished handwriting or digital art criterion.

- Make a larger paper guide, a quiet one-card version or an optional new challenge with explicitly new values.

## Review

A useful product has complete known source information, a supported route/value/check and truthful open reader outcomes. Quality of drawing or public sharing is not mathematical evidence.
