Prepare the specific original source pair, one learner choice card, and the public teacher-targeted key. Each day totals 4 + 5 + 7 + 11 + 5 + 3 = 35 minutes. The shared evidence target is (1) exact text maker/audience and one foregrounding or cropping choice, (2) correct model with unit and base, and (3) a revised public sentence that does not turn the model into a real-world recommendation. Choose A/B/C for the 11-minute response; all routes target the same reasoning and may be switched. Keep English text reasoning and General Mathematics reasoning visible separately. Neither the source pair nor its public check is a QCAA assessment instrument.
Day 21 · The extra hours did not make the whole shift
0–4 launch: Display only the Clockwork Museum caption and ask what two late hours foregrounds. 4–9 source: Attribute the fictional editor, describe the gloved-hand crop, then reveal the separate gross-pay note; no real worker is pictured. 9–16 model: Build three labelled layers on the wage mat: regular 7×$26, additional 2×(1.5×$26), once-only $15. Explain why a rate multiplier applies to its hour band, not all pay. 16–27 independent route: Learners choose a ledger, layered tactile cards or an editorial voice script and give a corrected caption. 27–32 peer/source check: Require $275 gross model total, exact layer values, and a statement that neither take-home pay nor display authorship is known. 32–35 exit: What part of the sentence can remain true, and what must change?
Day 22 · Once means once
0–4 launch: Have the class predict the effect of adding $10 once versus three times; do not show the total yet. 4–9 source: Read the Gym Index staff card and desk note, making the picture's three boxes distinct from evidence that the allowance repeats. 9–16 model: Regular 4×$30=$120; extra rate 1.25×$30=$37.50/hour. Put an allowance card outside the three-hour row. 16–27 independent route: A/B/C computes additional pay and total, then rewrites the card so an adult applicant can see the once-only condition. 27–32 audit: Compare the incorrect $262.50 obtained by repeating $10 for three hours with the correct $242.50. 32–35 exit: Name which unit $10 belongs to: per shift.
Day 23 · One dollar gap, two percentage bases
0–4 launch: Read 25% margin and ask what denominator it implies to a buyer. 4–9 source: Label the cycling clue-badge publisher's claim and the separate $56/$70 note; do not endorse an actual cycle route. 9–16 model: On the base comparison mat, calculate $14 difference, $14÷$56=25% mark-up and $14÷$70=20% gross price margin. 16–27 independent route: Learners annotate a catalogue, use cost/sale bars or dictate a source-bound correction. 27–32 audit: A peer circles the denominator under each percentage and strikes quarter of each $70 sale. 32–35 exit: Give a two-line correction that avoids claiming net profit or an actual beneficiary allocation.
Day 24 · The return percentage changes base
0–4 launch: Show the team's two imagined cropped price cards with 25% up, 25% down. 4–9 source: Reveal $96 and $120, and ask what the crop does not show about product quality or access. 9–16 model: Mark $24 rise as 24/96=25%; to return, $24 decrease is 24/120=20%. Put both bases on the change ladder. 16–27 independent route: Learners produce a two-step receipt, tactile ladder or private spoken/AAC explanation; the optional offline change-base lab follows a prediction and has a paper route. 27–32 audit: Pair checks whether a second 25% cut would reach $90, not $96. 32–35 exit: Replace the cancellation claim with an exact conditional return statement.
Day 25 · A crop cannot allocate every dollar
0–4 launch: Read the maker-fair summary and ask whether a close-cropped hand image proves how all $320 was distributed. 4–9 source: Distinguish gross receipts from three stated costs; no real fundraiser or maker is shown. 9–16 model: Verify 40×$8=$320, then sort $125, $45, $100 into cost categories; subtract to $50 known remainder before other unknowns. 16–27 independent route: A/B/C prepares a ledger-backed supporter line with a stated limit; do not invent where the remainder went. 27–32 audit: Another learner points to the exact every dollar overclaim and checks the sum $270. 32–35 exit: Collect “$50 remains after three stated costs, before other costs” plus one unanswered allocation question. Use separate fresh Check A in a later approved slot if it is new to that learner.
Day 26 · The photograph shows a label, not a reverse rule
0–4 launch: Read the mobile science-display caption with only the described $48 crop; ask what earlier value a viewer cannot see. 4–9 source: Reveal the $60 starting price and 20% decrease; the picture is an invented description, not a scientific record. 9–16 model: $60×0.20=$12, so $48; returning needs $12÷$48=25% increase. 16–27 independent route: Learners use a change ladder, proportional strips or a private explanatory script. 27–32 audit: Test the wrong repeated 20% of $48 = $9.60, giving $57.60, and explain why the crop makes the first base easy to miss. 32–35 exit: Give a claim naming both starting amounts and percentages.
Day 27 · Currency symbols are units
0–4 launch: Put USD $84 beside AUD $84 in matching type and ask why visual symmetry is not numerical equivalence. 4–9 source: State the animation club's rate is invented, not a current exchange quote; fees/spread absent by assumption. 9–16 model: On the direction mat, AUD 240 × 0.70 = USD 168; reverse USD 84 ÷ 0.70 = AUD 120. Check by multiplying AUD120 by0.70. 16–27 independent route: Learners annotate arrows, move labelled currency tokens or record a private brochure correction. 27–32 audit: Require both currency symbols beside every result and an unknown-real-rate warning. 32–35 exit: Give one correct conversion and reject “swap the sign, keep the number.”
Day 28 · One stipulated year is not forever
0–4 launch: Read Kite Ledger's promise and forever before showing its small-print model. 4–9 source: Distinguish a fictional one-year dividend from future payments; use the linked ASIC boundary without discussing personal investments. 9–16 model: $0.90/share ×40 shares=$36 in the stipulated year; $0.90÷$30×100=3% model dividend yield. Use the share measures mat. 16–27 independent route: A/B/C makes a one-year numerical correction and names what future information is absent. 27–32 audit: A peer distinguishes $0.90 per share from $36 for 40 shares, then removes guarantee language. 32–35 exit: State which part is computed and which part cannot be inferred.
Day 29 · A shorter bar cannot rank a company
0–4 launch: Display the imaginary $36 versus $48 bars and ask what the chart includes and omits. 4–9 source: Reveal $3 and $4 annual earnings per share from the separate note; all company data are invented. 9–16 model: 36÷3=12 and 48÷4=12; P/E is a ratio, not a percent or a prediction. 16–27 independent route: A/B/C calculates both, then rewrites the chart caption without investment ranking. 27–32 audit: A classmate points to an omitted factor such as future earnings or risk and refuses better-value as a proven conclusion. 32–35 exit: Say “same model P/E 12” and one thing it cannot decide.
Day 30 · Ten is not ten percent
0–4 launch: Show Soundwheel's ten-segment ring and ask why a picture might invite a unit shortcut. 4–9 source: Label the editor's ratio/percent conflation and three different desk-note quantities. 9–16 model: P/E=$20÷$2=10 as a ratio; yield=$0.60÷$20×100=3% for one stipulated year. Put labels on share measures before numbers. 16–27 independent route: Learners create a two-panel correction using equations, tactile cards or a private audio/AAC script. 27–32 audit: Partner checks that P/E is not a cash dividend, and future payments remain unknown. 32–35 exit: Collect ratio, yield, exact faulty word/visual choice and a source-bound correction. Give separate fresh Check B in an approved slot if its case is new to the learner.
Evidence log: day | source maker/audience and exact choice | model with unit/base | bounded revision | route and source access | content help | next move. Store only in a school-approved system; shared examples contain no real child data. QCAA mapping is partial; unit sequence and school instruments remain local decisions.
