Open Page Lab ten 35-minute integrated lessons Days 11–20Year 8 Inquiry · T1 W3–4 · Lesson sequence

Give learners the clean source packet, daily A/B/C routes and selected A4/text/tactile aids. The optional menu is additional, not a prerequisite. Give the new Day 15 and 20 checks as clean prompts when due; the teacher key is publicly accessible, so adapt locally if prior access matters. First responses remain distinct from edits. Record independent reading, exact adult read-aloud, calculator use, AAC, a directed scribe and prompts accurately; read-aloud gives listening comprehension, not independent print decoding. A mode does not define a learner. All people, figures and sites are fictional. No physical display, purchase, real survey or event is authorised by this pack. The common lesson rhythm is 3 + 5 + 7 + 12 + 5 + 3 = 35 minutes. Staff can pause a practical test for local safety; supplied constructed data allow the inquiry to continue.

Week 3 Day 11 Two rails, one claim with a hidden leap

Codes: AC9M8A01, AC9E8LY03. Goal: expand a two-rail paper rule and identify where the editor's headline exceeds the source. Prepare: Sources A/B, two-rail aid or its text route; two strips labelled RAIL 1/RAIL 2.

1. Launch · 3 min. Read the headline in Source A and ask, “Which part could a paper calculation check?” Keep “every reader” separate from width.
2. Model · 5 min. On the strips, show each rail has 12+18n+12=24+18n. Distribute the 2 across both 24 and 18n: T(n)=48+36n. At n=0, both forms give 48; substitution supports, while the two-strip grouping explains equivalence.
3. Guided · 7 min. At n=4, calculate one rail 96 and two rails 192 cm combined. Ask why 192 is not the width of one rail. Re-read the untested real-site conditions.
4. Independent · 12 min. Learners choose 11 A/B/C, showing the expression in two forms, a valid model result and one unsourced headline leap. Offer a calculator for arithmetic and record it separately.
5. Audit · 5 min. A partner points to “every story and every reader”. Ask what evidence would be needed beyond the dimensions; do not ask for personal access disclosures.
6. Exit · 3 min. “Two rails total , but one rail ; the source cannot show ___.” Use the daily key if a learner doubles only the panels.

Week 3 Day 12 Criteria before a prototype

Codes: AC9M8A01, AC9E8LA04, AC9TDE8K06, AC9TDE8P01, AC9TDE8P04. Goal: turn an overconfident design brief into testable paper criteria and a material choice. Prepare: Sources A/B/C, scrap A4, pencil, decision board.

1. Brief · 3 min. Ask what a visitor must understand from the draft and what a paper prototype could actually test. A paper width match is one criterion, not a safety certificate.
2. Model · 5 min. Write criteria with inspectable verbs: “each 96 cm drawn rail holds four drawn 18 cm panels plus margins” and “a caption names the paper condition.” Add a support test criterion: “compare flat and folded paper under the same small tab-load rule”; do not assign a pass threshold for a real installation.
3. Guided · 7 min. Compare flat and zigzag paper forms as different arrangements of the same material. Sketch how folding may change rigidity, then separate a prediction from evidence. Let learners suggest one sustainability criterion such as using offcuts or keeping reusable sheets, without pretending a full life-cycle assessment.
4. Design · 12 min. Choose 12 A/B/C. Each route yields two criteria, a labelled paper design/material option and a paragraph linking a source, reason and still-unknown condition. Learners can model 2(24+18n) with strips if needed.
5. Critique · 5 min. Test whether criteria can be checked with the supplied information or small paper test. Replace “accessible for all” with a specific reader-test question; actual accessibility needs remain for local review.
6. Exit · 3 min. Name one criterion the drawing meets and one it cannot yet meet. Keep the selected material/shape rationale for Day 13.

Week 3 Day 13 A paper support is a test, not a wall certificate

Codes: AC9S8I01, AC9S8I02, AC9S8I03, AC9S8U05, AC9TDE8P02. Goal: conduct or direct a reproducible paper-support test, record trial evidence and observe a simple potential-to-kinetic energy change if a light tab moves down. Prepare: Source C, test card, paper, equal supports and ruler; teacher checks local safety. Constructed fallback is an equal analysis route.

1. Question · 3 min. Learners predict whether fold geometry may change tabs held, and explain why the prediction is provisional. Do not announce the constructed table as a class result.
2. Protocol · 5 min. Demonstrate a 15 cm span, 2 cm rests, equal tabs, three-second wait and 1 cm sag stop. Keep stock, span, placement and tab size as similar as possible; shape is the planned change. Stop if supports slip.
3. Guided trial · 7 min. Test one flat and one folded paper bridge or trace the protocol with prepared cards. Count successfully held tabs before the stop, not a guess at mass. If a light tab moves down, identify gravitational potential energy decreasing and kinetic energy increasing; no energy amount is measured.
4. Independent · 12 min. Use 13 A/B/C: carry out/record further safe repeats, direct a partner's procedure, or analyse the clearly marked constructed three-trial table. All routes identify variable, controlled conditions and one possible error. Record own data as own data; never merge it silently with fallback data.
5. Method check · 5 min. Ask whether different creases or support movement could explain a result. Revise a procedure line. Do not infer real mounting safety.
6. Exit · 3 min. Give a result with its source label and one repeat or control that would improve confidence. Staff next moves.

Week 3 Day 14 Make the margin mean something, then test the reading

Codes: AC9E8LE03, AC9S8I04, AC9S8I06, AC9AVA8D01, AC9AVA8C01, AC9AVA8C02. Goal: distinguish measured model space from an artist's proposed reader effect, represent the paper trial honestly, and make two original visual-caption studies. Prepare: Sources B/C/F, decision board, scrap paper and dark pen; do not copy real artworks or cultural motifs.

1. Open · 3 min. Read the fictional artist's “invitation or wall” line. Ask what the line means literally on paper and what is interpretation.
2. Model · 5 min. Make two tiny caption compositions using the same words: one crowded at an edge, one with a left margin and large source label. Describe choices in spacing/emphasis without claiming everyone will feel the same.
3. Evidence · 7 min. On a simple two-row table, identify flat and folded results as constructed fallback if using Source C. Their means are 4/3 and 13/3 tabs. Discuss small sample and nonstandard folds; do not use these numbers as a real safety limit.
4. Make · 12 min. Choose 14 A/B/C. Produce two original composition variants plus a 1–2 sentence note on the intended viewpoint. A consenting reader points to where the model source and limit appear; the maker revises one spacing/word choice.
5. Compare · 5 min. Ask which variant communicates source reach more clearly and which view is one reader's interpretation. Record the reader's exact response as a small test, not a population preference.
6. Exit · 3 min. State one visual convention changed and its proposed effect, plus a limit of the paper-test evidence.

Week 3 Day 15 Fresh plan transfer check

Codes: AC9M8A01, AC9E8LY03, AC9TDE8P01. Goal: independently interpret a new repeated-paper rule, critique a headline and propose one bounded design test. Prepare: fresh Check A and public teacher worked key. Do not rehearse its numbers or phrasing.

1. Frame · 3 min. Tell learners that the source is new. They may use known representation aids and access supports, not a hint about its answer.
2. Read · 5 min. Give the exact new source. Record independent print or adult reading. No model answer is shown.
3. First pass · 7 min. Learners independently mark repeated parts, a supported result, an unsourced phrase and one missing real-world observation. Preserve first marks.
4. Response · 12 min. Choose 15 A/B/C to produce the same expression explanation, claim boundary, specific next test and reader-facing correction. Note arithmetic support separately.
5. Self-audit · 5 min. Learner points to a source number and circles a limiting word in their revision. Keep edited and first versions.
6. Collect · 3 min. Staff use criterion next moves later; no one result decides a whole Year 8 standard or real design approval.

Week 4 Day 16 The slot model cannot count people

Codes: AC9M8A02, AC9M8A03, AC9E8LA03, AC9E8LY03. Goal: solve and check the demo-time inequality while repairing the hybrid headline's audience claim. Prepare: Source D, decision board; no actual event planning.

1. Contrast · 3 min. Read “everyone gets a demo” beside 5+15d≤50. Ask what quantity each statement concerns.
2. Model · 5 min. Subtract 5 and divide by positive 15: d≤3. State d must be a non-negative whole number. Check d=3 gives 50 and d=4 gives 65, outside the 50-minute model.
3. Guided · 7 min. Plot or list d=0,1,2,3,4 with totals 5,20,35,50,65. Circle allowable whole counts. Note the headline cannot infer attendance or actual access from a run count.
4. Independent · 12 min. Choose 16 A/B/C: number line/table, caption repair or spoken/AAC source challenge. Each cites the condition, a substituted check and a limitation.
5. Audit · 5 min. Challenge “three runs means three people” and “50 minutes includes questions”. Source D states neither. Have learners rewrite one sentence for a new reader.
6. Exit · 3 min. Give the largest complete model demonstration count and one question before any real promise. If inequality sense reverses, return to substitutions.

Week 4 Day 17 A price can change a resource choice

Codes: AC9M8A03, AC9HE8K01, AC9HE8S03, AC9HE8S04. Goal: compare two fictional supplier rules at relevant panel counts and explain how a price change could shift a constrained choice. Prepare: Source E, two-rail aid, 30-token paper budget.

1. Question · 3 min. “Does cheaper per panel always mean cheaper total?” Identify setup fee and panel count before recommending.
2. Model · 5 min. At four total panels, F 12+2×4=20, G 4×4=16, so G has a lower listed total by 4. At eight total panels, F 28 and G 32; F is within the fictional 30-token budget while G is above.
3. Guided · 7 min. Solve 12+2p=4p to find p=6, each 24 tokens. Compare p4/p8 to the crossing; distinguish p total panels from n per rail. Discuss how a supplier's quoted price might influence which input a fictional group can allocate while stock and quality remain unknown.
4. Independent · 12 min. Choose 17 A/B/C. Each gives a count-specific cost comparison, a budget interpretation and the effect of the what-if G increase to 6 per panel at p4. The scenario is invented, not a claim about a real market.
5. Cost–benefit audit · 5 min. Ask whether material suitability, waste and access are priced. Have learners name a benefit or cost not measured and a source they would seek before a real purchase.
6. Exit · 3 min. “At p4 I would choose ___ on listed cost only; if G changed to 6 per panel ; I still need .”

Week 4 Day 18 Make a model tool answerable to its reader

Codes: AC9E8LY06, AC9TDI8P07, AC9TDI8P10. Goal: test a small offline interface against a user story, then revise a user-experience element so model result and scope remain visible. Prepare: Source F, the optional offline model-audit tool in a browser, plus the paper equivalent. No account or internet is needed.

1. User story · 3 min. Read what the fictional reader wants: a whole-number input, model result and plain-text limit. Name the audience and task before touching a control.
2. Demonstrate · 5 min. Enter a valid count in the offline tool; read both its numeric result and the nearby “paper model only” statement. Use the paper route if a device or interface is unavailable; this route gives the same English/math access but not evidence of actually testing a digital interface.
3. Test · 7 min. Try zero, a valid whole count, an invalid negative/decimal entry and keyboard-only navigation. Observe exact displayed words; do not type names or real site dimensions.
4. Revise · 12 min. Choose 18 A/B/C. If using the digital route, sketch or implement one small label/order/message change and re-test it with a consenting reader. Paper-only learners may create an interface wireframe and explain predicted effect; record as design reasoning, not actual digital interaction.
5. Evaluate · 5 min. Compare the original/revised interface with the user story: does a reader see unit, source limit and error feedback? Note one unresolved accessibility issue without claiming certification.
6. Exit · 3 min. State one actual test observation and one design improvement. If no device was used, state that honestly.

Week 4 Day 19 A recommendation the editor can inspect

Codes: AC9E8LY06, AC9E8LY07, AC9HE8S04, AC9TDE8P02, AC9AVA8C02. Goal: combine source-specific model results, test limits, cost comparisons and visual wording in a private recommendation. Prepare: Sources B–G, learner drafts, decision board. A spoken/AAC delivery is offered; write the observed mode rather than assuming one.

1. Audience · 3 min. Re-read Source G. The editor can change a paper proposal, not authorise a real installation. Learners choose a one-rail, two-rail or postpone recommendation.
2. Model · 5 min. Give a deliberately bounded example: “Four panels match each drawn rail, but support and site are untested. At eight panels total, F's listed 28 tokens are within the imaginary budget; material quality is unknown. I would revise the caption before any further test.” Attribute each sentence to B, C, E or F.
3. Plan · 7 min. Order evidence card → limitation → design/caption choice → next check. A visual composition may put model result and limit at equal readable prominence.
4. Create/deliver · 12 min. Choose 19 A/B/C. Make an original one-page recommendation or privately rehearse and deliver a 45–60 second spoken/AAC presentation with a labelled visual. Reuse no actual child image or cultural motif. A written-only route is valid composition but not spoken-performance evidence for AC9E8LY07.
5. Reader test · 5 min. A consenting partner/teacher identifies which source supports the cost, width and material claim, and asks one question. Learner revises the caption or presentation order, recording what changed.
6. Exit · 3 min. “I recommend ___ for the fictional paper draft, because ; I would not yet claim .” Keep draft and revision.

Week 4 Day 20 Fresh decision transfer check

Codes: AC9M8A02, AC9E8LY03, AC9HE8S04. Goal: interpret a new time-and-cost source, reject an unsupported universal promise and recommend one bounded next step. Prepare: fresh Check B, separate public teacher key.

1. Frame · 3 min. Tell learners the source is fresh and they should separate minutes, run counts, paper-copy counts and people. Do not foreshadow its values.
2. Read · 5 min. Give the source exactly, recording independent print or access reading.
3. First pass · 7 min. Learners mark a condition, one valid result, an overclaim and a cost comparison. Preserve first work.
4. Respond · 12 min. Choose 20 A/B/C, each yielding a source-bound decision note with a tested model value, cost comparison, audience limit and specific question.
5. Self-audit · 5 min. Point to the line behind each number; circle a phrase that prevents a real-world overclaim. Keep changes visible.
6. Collect · 3 min. Staff select the criterion next move. The result does not grade complete Year 8 English, mathematics or economics.
