# HASS · Year 9 · optional Days 11–20

Ten **12-minute** blocks sample Geography, History inquiry, Civics and Citizenship, and Economics and Business. They are not a substitute for the substantial real-source work and local study required in any strand. Imaginary service maps, tallies, archive labels and business choices are identified as **simulations**. In History, a card pretending to be old is **not** a genuine primary source. The [HASS decision mat](print/hass-source-grid.pdf), [learner copy](LEARNER-COPY.md), [public formative checks](ASSESSMENT.md) and [teacher key](teacher/ANSWER-AND-NEXT.md) support the tasks. Consult the [AEC](SOURCE-AND-RIGHTS.md) for the real referendum rule; no fictional vote here describes an actual proposal.

### Day 11 · Travel time is one part of access · AC9HG9K05, AC9HG9S03
**Kit:** invented service map: route A from Stop P to Library L is 12 minutes and has no step-free information; route B is 7 minutes to Stop Q plus 10 minutes onward and is marked step-free in the *fictional* timetable. 0–2: Label both routes hypothetical. 2–4: Predict which is quicker and what access question remains. 4–10: Compare 12 and 17 minutes, then state why the shorter route cannot be called accessible without missing information; choose what should be checked with a real provider. 10–12: Check: A is 5 minutes faster in the stated model, not automatically the better option. **Routes:** order route tiles; trace raised/text map; explain a two-criterion choice. **Response move:** if “fastest” becomes “best for everyone”, add mobility, cost and timetable questions. **Home:** write a respectful transport-information request, no trip required.

### Day 12 · A connection has dependencies · AC9HG9K07, AC9HG9S05
**Kit:** imaginary library repair club obtains blank notebooks from Workshop W, 30 fictional units by route North or 22 by route South, with no reliability or impact data. 0–2: Name the invented trade network and units as planned quantities, not deliveries. 2–4: Predict one dependency if North closes. 4–10: Draw both paths, compare available planned capacity and propose a strategy under environmental, economic and social criteria **without declaring it sustainable**. 10–12: Check: 22 planned units do not prove 22 delivered or a lower environmental impact. **Routes:** connection string board; table comparison; audio/AAC decision memo. **Response move:** if a recommendation ignores unknown cost/emissions, label those as data to seek. **Home:** identify a service dependency in a fictional story, not a household purchase.

### Day 13 · A simulated old card is not an archive · AC9HH9S02, AC9HH9S03
**Kit:** two **newly authored classroom simulations**, not historical evidence: Card A imitates an 1884 workshop note about a broken tool; Card B is a present-day exhibit caption explaining A. Neither was found in an archive. 0–2: State provenance aloud. 2–4: Predict what A *would* be if an authenticated contemporaneous note and what B would be. 4–10: Sort hypothetical primary/secondary status, list three checks before citing a real document (origin, date, context), and refuse to infer 1884 working conditions from these fabricated cards. 10–12: Check: an old-looking font does not authenticate a source. **Routes:** provenance cards; text annotation; curator interview role-play. **Response move:** if learners treat A as a real primary source, show the “authored now” label and ask what archive identifier is absent. **Home:** practise the three provenance questions on a made-up object.

### Day 14 · A referendum needs two majorities · AC9HC9K01
**Kit:** [AEC rule](SOURCE-AND-RIGHTS.md): national yes majority *and* yes majorities in at least four of six states. Invented tally: each of fictional States A–F has 100 votes; yes counts `80, 80, 80, 45, 45, 45`; territories together have 30 yes and 70 no. 0–2: State this is an arithmetic model, not an Australian result. 2–4: Predict whether national yes alone would carry it. 4–10: Calculate national yes `405/700`, no `295/700`; only three states have yes majorities. 10–12: Check: the model fails the state-majority condition despite national yes. **Routes:** six count cards; tactile yes/no piles; spoken two-part explanation. **Response move:** if territories are counted as a state, distinguish their national votes from the six state tests. **Home:** write the two conditions in your own words without political persuasion.

### Day 15 · Fresh HASS check A · AC9HG9K05, AC9HC9K01
**Kit:** new fictional route and referendum tally [H-A](ASSESSMENT.md); prompt and key are public. 0–2: Recall two-criterion decisions and the AEC double-majority rule, not the case values. 2–4: Give access modes; if prior access matters, substitute a locally new but equivalent case. 4–10: Collect a first response. 10–12: Note arithmetic, source status and missing access information separately. **Routes:** count/route tiles; text table; dictated explanation. **Response move:** after collection, reteach a missed condition with different counts. **Home:** make a fictional two-route comparison with one explicit unknown.

### Day 16 · Who is missing from a media claim? · AC9HC9S03
**Kit:** invented social post about a venue survey: “Everyone wants late opening”; fictional attached tally says 18 responses, 12 yes, 6 no, sampling method absent. 0–2: Say no venue or poll is real. 2–4: Predict whether “everyone” is warranted. 4–10: Replace with “12 of 18 recorded responses favoured late opening”; ask who was invited, which views may be missing and how framing can shape attitudes to a community choice. 10–12: Check: 12/18 is two-thirds of recorded responses, **not** all residents. **Routes:** count tiles; highlight wording; propose an accessible question script. **Response move:** if a learner calls the 18 representative, ask for sampling evidence. **Home:** make one fairer fictional headline, no actual posting.

### Day 17 · One decision affects several roles · AC9HE9K02, AC9HE9S03
**Kit:** imaginary repair stall: a customer requests a fix; a business orders a part; a bank processes a payment; a council sets venue rules. No real provider is described. 0–2: Name roles as a simplified interdependence model. 2–4: Predict two effects if the part is unavailable. 4–10: Draw a four-node chain and distinguish an observed *stipulated* link from a possible effect; explain why a delayed part might affect timing, while its actual price is unknown. 10–12: Check: the customer, business, finance service and government do not all perform the same function. **Routes:** role cards; textual arrows; narrated scenario. **Response move:** if a role is missing, ask who pays, supplies or sets the rule. **Home:** describe a different fictional service chain without personal finance details.

### Day 18 · A cost comparison needs criteria · AC9HE9K05, AC9HE9S04
**Kit:** imaginary repair-stall shelf choices: A costs 30 fictional credits and is planned for 15 uses; B costs 45 and is planned for 30 uses. Neither durability nor actual use is measured. 0–2: Explain “credits” are invented and this is not buying advice. 2–4: Predict the cost per *planned* use. 4–10: Calculate A=`30/15=2`, B=`45/30=1.5` credits per planned use; add two criteria such as stability and access, and explain why the cheaper ratio alone cannot decide. 10–12: Check: B's lower planned unit cost is conditional on its 30 uses occurring. **Routes:** counters/fraction strip; calculation table; verbal criteria matrix. **Response move:** if a learner declares B “best”, ask for the unmeasured durability/access factors. **Home:** propose one non-price criterion for an imaginary item.

### Day 19 · Interpretations require real evidence · AC9HH9S04, AC9HH9S07
**Kit:** two invented modern exhibit captions about the **simulated** 1884 tool note from Day 13: Caption 1 says the break proves poor maintenance; Caption 2 says it may have been an isolated accident. They are not historical interpretations of a real event. 0–2: Reassert source status. 2–4: Predict which caption makes the stronger causal claim. 4–10: Mark each caption's inference, write one genuine archive source a historian would seek (e.g. maintenance ledger) and compare what that source might or might not resolve. 10–12: Check: neither caption establishes a fact about nineteenth-century workers. **Routes:** evidence ladder; spoken debate with source tags; tactile claim/evidence sort. **Response move:** if either caption is accepted as history, return to provenance and absent corroboration. **Home:** draft a cautious museum label for a fictional object.

### Day 20 · Fresh HASS check B · AC9HH9S03, AC9HE9S04
**Kit:** new simulated archive and fictional service-choice case [H-B](ASSESSMENT.md); public key, not a secure exam. 0–2: Recall provenance and multi-criterion cost-benefit language. 2–4: Give access instructions without working the case. 4–10: Collect a first response or use locally novel parallel figures. 10–12: Record source-status reasoning and decision criterion separately. **Routes:** source labels; text table; dictated decision memo. **Response move:** after collection, show why “old-looking” and “lowest price” are insufficient on their own. **Home:** one question you would ask before relying on a source or quote.
