# Learner cards · choose a route, keep the evidence target

Read or hear the matching [fictional public text and desk note](SOURCE-CARDS.md). Every A/B/C choice produces the same three-part response: **(1)** identify maker, audience and one exact foregrounding, crop or wording choice; **(2)** show the arithmetic with its units and correct rate/base/direction; **(3)** give a useful revised public line and an unknown. These are switchable access and exploration routes, **not fixed learning-style labels**. Use paper, calculator, large print, Braille, labelled tactile pieces, sign, AAC, typing or a directed scribe. Say what support you used; a read-aloud does not by itself demonstrate independent reading. You will never be asked for a real payslip, family finances, current exchange quote, share ownership, disability, identity or public recording.

## Day 21 · Clockwork Museum

- **A · Caption and ledger:** Cross out the claim that late hours built the *whole* display; itemise 7 regular hours, 2 additional hours and the once-only allowance before drafting a new caption.
- **B · Three pay layers:** Build labelled REGULAR, ADDITIONAL and ONCE cards; direct a partner to place them under the cropped-hand description, then explain what the crop cannot identify.
- **C · Reader's voice note:** Privately dictate the three gross-pay layers, calculate the `$275` model total and record a correction for fictional newsletter readers with one authorship unknown.

**Optional extra / paper home:** What if the additional-hours multiplier were an invented `1.25` instead? Change that layer only and keep all real pay-rule claims out.

## Day 22 · Gym equipment index

- **A · Error audit:** Show the wrong sum that counts `$10` three times, correct it with the note's **one shift** unit, then rewrite the staff card.
- **B · Hour-band strip:** Place four regular-hour tokens, three extra-hour tokens and a single allowance token; attach the rate to the relevant band and explain why the drawing is not a pay rule.
- **C · Adult-applicant script:** Ask how often the allowance applies, compute the model answer and dictate an accurate shift summary without claiming take-home pay.

**Optional extra / paper home:** Try one invented additional hour rather than three; the allowance still appears once. No real worker information is needed.

## Day 23 · Cycling clue badges

- **A · Catalogue editor:** Annotate the `$56` cost and `$70` sale with the `$14` gap, then label 25% **mark-up on cost** and 20% **gross margin on sale** in a replacement line.
- **B · Base bars:** Make one 56-unit COST bar and one 70-unit SALE bar; place the same 14-unit gap against each full bar and explain the changed percentage denominator.
- **C · Publisher dialogue:** In a private script, ask what *quarter of each sale* means; show why `$14` is a fifth of `$70`, not a quarter, and name expenses still unknown.

**Optional extra / paper home:** If a fictional second badge costs `$28` and sells for `$35`, compare the two percentages without saying anything about real profit.

## Day 24 · Quiet-space paper panels

- **A · Two-base receipt:** Show `$96 → $120 → $96` with `$24` on each arrow, then write the percentage under its own starting amount and edit *cancel*.
- **B · Change ladder:** Arrange BASE 1 `$96`, HIGH `$120` and RETURN `$96` cards; use the [A4 ladder](print/change-ladder.pdf) or text route to explain the different 25% and 20% steps.
- **C · Predict/test/explain:** Predict whether another 25% decrease works, then use the [offline base lab](interactive/change-base-lab.html) or [paper equivalent](interactive/TEXT-ROUTE.md); publish a cautious correction.

**Optional extra / paper home:** Test a rise from `$40` to `$50` and find the decrease needed to return. No actual price search is required.

## Day 25 · Tabletop maker fair

- **A · Supporter note:** Annotate *every dollar* and the cropped hands; show `$320` receipts, `$270` stated costs and `$50` remainder before rewriting the summary.
- **B · Cost pockets:** Put 40 `$8` receipts in a GROSS pocket and `$125`, `$45`, `$100` in three COST pockets; name what the imagined crop omits and keep the allocation unknown.
- **C · Editor interview:** Privately ask the organiser where the remainder went, answer “the source does not say”, and dictate a supported line for supporters with the arithmetic.

**Optional extra / paper home:** Add an invented `$20` cost and recalculate a new what-if remainder; do not portray it as an actual expense.

## Day 26 · Mobile science-display board

- **A · Crop annotation:** Describe what the `$48` image includes and excludes; show `$60 → $48 → $60` with 20% down and 25% up.
- **B · Proportional strips:** Remove a `$12` strip from `$60`, then compare that same `$12` with the new `$48` base; label why the return percentage is bigger.
- **C · Fact-check script:** Predict a 20% increase on `$48`, compute `$57.60`, then dictate a correction that does not call the fictional image a real observation.

**Optional extra / paper home:** Try a `$100` starting value with a 10% cut, then calculate the exact percentage rise needed to return, to a sensible decimal place.

## Day 27 · Animation sound-cue licence

- **A · Brochure markup:** Draw `AUD→USD` and `USD→AUD` arrows and place `$168 USD` and `$120 AUD` beside the correct givens before rewriting the brochure.
- **B · Currency tiles:** Move 240 AUD-labelled tokens through groups of `0.70 USD per AUD`; reverse-check 84 USD by locating the AUD amount that produces it. Keep symbols on every card.
- **C · Two-reader explanation:** Privately explain to fictional AUD and USD readers why matching typography is not matching value, then give both model conversions and a no-real-quote limit.

**Optional extra / paper home:** Choose a different invented rate, such as `0.50 USD per AUD`, for a what-if; never present it as a live quote or conversion instruction.

## Day 28 · Kite Ledger flyer

- **A · Flyer correction:** Identify *forever* and *promise*, then calculate `$0.90/share × 40` and `$0.90 ÷ $30 ×100%` for one stipulated year.
- **B · Share stacks:** Make forty cards labelled ONE SHARE, each with model `$0.90` one-year dividend, and one `$30/share` price card; distinguish portfolio dollars from per-share yield.
- **C · Cautious explainer:** Dictate an imagined reader's question about next year, answer “unknown”, then privately record the one-year `$36`/3% calculation and a safer sentence.

**Optional extra / paper home:** Suppose the fictional dividend were `$0.60/share` in a different year; recalculate the model yield while saying the new value is invented.

## Day 29 · Tinpath and Hearthtile

- **A · Chart editor:** Put `$3 EPS` beneath Tinpath's `$36` bar and `$4 EPS` beneath Hearthtile's `$48` bar; calculate both P/E ratios and revise *better value*.
- **B · Ratio cards:** Group 36 price units in sets of 3 earnings units and 48 in sets of 4; both form 12, then name one factor the bars never showed.
- **C · Magazine response:** Privately dictate a note to the fictional editor: the lower nominal share price is visible, both model P/E ratios match, and no investment rank follows.

**Optional extra / paper home:** Invent a third company with a different price/EPS pair but the same P/E 12; do not use a real company.

## Day 30 · Soundwheel Papers

- **A · Two-panel infographic:** In one panel compute P/E `20÷2=10`; in another compute dividend yield `0.60÷20×100=3%`. Caption the two units separately.
- **B · Measure tokens:** Use labelled PRICE, EARNINGS and DIVIDEND cards; build the two quotients on separate rows and explain why the ten-segment ring conflates them.
- **C · Reader correction:** In a private spoken/AAC script, name the editor's *ten is ten* shortcut, give ratio 10 and one-year yield 3%, and reject future-cash inference.

**Optional extra / paper home:** Change the fictional dividend to `$0.40/share` while leaving price and earnings unchanged; note which measure changes. The [new-case Check B](STUDENT-CHECKS.md) and [public key](teacher/KEY-AND-NEXT.md) are available by URL, so the check is formative, not a secure exam.
