The following texts, characters, numbers, diagrams and organisation names were created for this pack. Model means invented classroom material. Paper shapes are not biological specimens; the workshop and gallery are not real places. Give a selectable-text copy, a locally read version, large print or a tactile/text map. A read-aloud can open the same analysis, but record it as listening-supported comprehension, not independently decoded reading. These texts are deliberately varied in sentence length and vocabulary for Year 7 discussion; no blanket decodability claim applies to an individual learner. Preview vocabulary without supplying the interpretation. No published author, cultural story, private pupil data or real locality is embedded.
Text A · A new card reaches an old label (fictional test log)
During the first fortnight, Mira's group changed its paper-shape key. The first question now said: Look at the whole outer edge. If any section is jagged, take the jagged route. Two groups could finally follow that question in the same way.
For a new test, an editor gave the group card 8. It was a paper outline with a short jagged notch on one side. Card 8 had not been in the original six-card set. Mira placed it squarely on the table so everyone saw the same side. Dev followed the key without a hint and reached the printed terminal label J, one of the original six labels. Mira reset the card, followed the same arrows and also reached J.
“So it is J?” Dev asked.
“We know we took the same route,” Mira said. “The key was built for six cards. It has no terminal label for an eighth.”
Their record had three lines:
| Test | What the paper route showed | What the route could not show |
|---|---|---|
| Dev's first pass | Card 8 followed the jagged branch and ended at J. | Whether J was a justified identity for card 8. |
| Mira's second pass | The same branch and terminal label appeared. | Whether another new card would behave the same way. |
| Proposed revision | Add an unmatched/new-card exit after the feature questions. | Whether any paper label corresponds to a real organism. |
The two passes supported a repeatability claim about this route. They did not prove the terminal label identified card 8 correctly, and no real species was tested. Their next question was more useful than a quick celebration: What additional feature would separate card 8 from the original labelled cards?
Teacher source note
The new issue differs from Days 1–5: the question itself is now unambiguous, but the scope and terminal label remain untested. The group ran two passes with the same physical paper model. The proposed exit has not yet been made or tested. Do not turn “two people agreed” into “the identification is true”.
Text B · Two gallery labels for the same model (paired nonfiction drafts)
Draft One — confident caption: “Our key identifies every leaf. Card 8 has a notch, so it is J. Two testers agreed. The method is proven.”
Draft Two — scoped caption: “In our paper-card model, a notch sent card 8 down the jagged route. Two testers reached terminal label J in separate passes. Their agreement shows that the route was repeatable in these two passes. It does not establish that J is the right label for this new card or that the model identifies real leaves. A new-card exit and a separating feature still need testing.”
Display brief: The captions are for visitors who have not seen the group work. They must learn what the test actually showed and what remains unknown. Neither caption is an official museum or science statement. The gallery and its display are fictional.
Teacher source note
Draft One compresses an observation into three unsupported universals: every leaf, is J, proven. Draft Two separates the observed route from correctness and context. It has an overview, evidence, limit and next test. Students may critique its length or jargon for a younger visitor while keeping its accuracy.
Text C · Editor's margin notes (fictional responses)
Note 1, from Ren, a peer reader: “I could follow the arrows once you told me to look at the whole edge. Before that, I inspected only the notched side. The first sentence needs to name the viewing rule.” Ren reports one test of instructions, not a verdict about the label.
Note 2, from Sol, a visitor to the paper display: “The arrows look professional. That means the key will work for plants in the school garden.” Sol reports an impression. Sol did not test garden plants or supply a source for that claim.
Note 3, from the fictional display editor: “Put the result in one sentence, then explain the limit in the next. Keep the word terminal only if you define it: the label at the end of a route. A visitor should not need the author beside them.”
Teacher source note
Ren's observation is relevant to reproducibility but narrow. Sol's aesthetic judgment is not a biological test. The editor's advice concerns audience and cohesion. Students should attribute a claim to its source and its actual evidential reach, even when the source is invented for practice.
Text D · The same marks can name different quantities (original explainer)
The number 36 can be written as 6 × 6, 4 × 9, or 2² × 3². These expressions all have value 36. In mathematics, a factor is a number multiplied with another to make a product; 4 and 9 are factors of 36. In everyday conversation, a factor may mean something that influences a decision, such as travel time. The shared word does not make the two meanings identical.
A power is not a louder or more important number. In 2², the small 2 tells us to multiply two copies of 2, giving 4. Therefore 2² × 3² = 4 × 9 = 36. The same word power can mean influence in an ordinary conversation. Context tells a reader which meaning is doing the work.
One symbol changes the comparison: 36% means 36 out of every 100 of a specified whole, or 0.36 of that whole. It is not the number 36. If the whole is 50 model seats, 36% of it is 18 seats. A count of 36 seats is twice that. If the whole is 100 seats, 36% happens to give a count of 36 seats; this special case does not erase the difference between a proportion and a count.
For a second example, 3/4 = 0.75 = 75% as numbers or proportions. A ratio written 3:4 needs its own context; it is not automatically another spelling of 3/4 of a whole. Before telling a younger reader that two forms are “the same”, state what is being counted or compared and identify the whole.
Teacher mathematical check
Check arithmetic aloud or with a calculator: 2² = 4, 3² = 9, 4 × 9 = 36, and 0.36 × 50 = 18. The 36-seat example has a model whole, not a real capacity. In the three-quarter line, 3/4, 0.75 and 75% are equivalent quantities; 3:4 is a ratio of two parts and is left deliberately outside that equality. The sentence about ratio needs its context, not a blanket claim that ratios and fractions can never be related.
Text E · The label at the repair bench (original literary vignette)
The cardboard bike model stood on Isha's desk, leaning toward the window as if it wanted to leave before the workshop opened. The event was a fictional school design show. Nobody would ride the model. Isha and her friend Luca were making a sign so a visitor could understand how its folded-paper stand worked.
Luca drew a careful blue arrow to the broad part at the bottom. “Base,” he wrote. Then he drew three smaller arrows, each pointing toward a different fold.
Isha read the sign from the doorway. The arrowheads crowded one another. “Which fold is the base?” she asked.
“The broad one. It's obvious when you're here.”
“We're making this for someone who isn't here with us.” She moved back to the desk and tried reading the sign with her hand over the model. Without Luca's explanation, base could mean the flat support, the starting line of a measurement, or simply where to begin looking.
They removed two arrows. Under the remaining one, Isha wrote: Base: the wide paper support touching the table. Luca tested the sign from the doorway and found the right fold without help. They added a short text description for anyone who could not use the arrows.
When the bell rang, the model was still leaning. They had improved the sign, not the stand. Luca was disappointed for half a second, then smiled at the separate problem they had found. “At least we know where to start.”
Isha looked at the word base once more. It was both a named part and, today, a place from which a better question could begin.
Teacher literary note
The literal base is the paper support. The final base also suggests a starting point for thought. The leaning model, doorway and crowded arrows create a small problem about audience; they do not prove the device's engineering quality. Luca's change is supported by his doorway test and last line. Discussion can compare defensible readings without requiring a single emotional response.
Text F · Route with a margin (original short poem)
First I drew a line so straight
I thought it knew the way.
Then someone stopped beside its edge
and asked what I would say
if their next step did not fit
the arrow I had made.
I left a margin on the page:
another route may wait.
Teacher literary note
The line is personified as knowing a way; a paper margin becomes room for uncertainty. The poem is not an instruction to leave every practical route vague. A reader may connect it with the paper key, a conversation or a decision, and should point to words that support that interpretation. Read or feel the line breaks before discussing why fit is not literal size here.
