# Full print, text and tactile routes

All three aids are original black-on-white A4 SVG/PDF. Print at **100%** on A4; no colour is needed to tell branches apart. The visible words are the authoritative data. A teacher or learner may use this page on a screen reader, enlarged device or plain paper. A tactile route uses three labelled strips or cards per input; **never ask someone to infer a trait from the drawing**. The underlying cards are fictional and are not for real plant identification.

## [Model profile board](model-profiles.pdf)

The page has two columns and five rows. Reading order is row by row: S1, S2, S3, J1, J2, J3, T1, T2, T3, T4. Each card displays ID and **entire edge / tip / stem** in words:

1. S1: smooth / rounded / long.
2. S2: smooth / rounded / short.
3. S3: smooth / pointed / short.
4. J1: jagged / rounded / long.
5. J2: jagged / pointed / long.
6. J3: jagged / pointed / short.
7. T1: smooth / rounded / short.
8. T2: jagged / pointed / long.
9. T3: smooth / pointed / long.
10. T4: mixed (one smooth side and one jagged side) / rounded / short.

Make tactile cards by writing each ID in large print/Braille if locally available, plus **separate labelled** edge, tip and stem strips. Optional edge textures can be smooth strip, notched strip and half-and-half strip; the **word label** remains essential. Compare three words for a full match. Long stem has only the stipulated meaning in [source packet](../MODEL-SOURCES.md).

## [Nested key and trace mat](key-trace.pdf)

Top input fields: card ID, entire edge, tip, stem. The left side **starts one branch** of a flowchart with a start/input box, a first diamond for the entire-edge condition, then a **nested** diamond for tip/stem test. Continue the other branches on scrap paper; the printed diamonds alone are not a complete algorithm. At the bottom, there is a line for `condition → branch → candidate → verification → output`. The right side starts corresponding nested `IF` pseudocode; continue any missing branches on paper, then add `IF all 3 traits match candidate / OUTPUT candidate / ELSE OUTPUT unmatched`. Learners fill actual conditions from Version 1 or 2; the mat does **not** supply an answer.

For a tactile/text equivalent, place cards in this order on a desk or read them in order: **input → edge test → branch → nested tip/stem test → candidate → compare all three baseline traits → output or unmatched**. Use a recorded trace line rather than an arrow drawing. A decision card must be read in words; shape/position alone is not the information.

## [Four-frame explainer](explainer-storyboard.pdf)

Reading order: top-left frame 1, top-right frame 2, bottom-left frame 3, bottom-right frame 4. Headings: (1) overview/question; (2) first explained step; (3) next step and evidence; (4) verify and honest limit. Each has ruled space for main words or audio script and a small optional visual/tactile cue box. To work without the sheet, write the four numbered headings on ordinary paper and give complete sentences. For audio/AAC, speak or enter headings in order; no recording is needed. For tactile, four numbered large cards in a line carry the same words. A reader must be able to follow the text **without colour, arrows or an optional image**.

If a learner cannot perceive or manipulate a page, a neutral reader can describe each labelled field and the learner can choose/compose independently. Record any **content hint** separately from access support. Original SubjectNest alt route © NeuroForgeIO Pty Ltd 2026, [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/).
