# Four A4 aids · full text and nonvisual adaptation

The four original SVGs have title/description elements, and their matching A4 PDFs contain selectable embedded-font text. The sequence is never encoded by colour alone. For tactile use, print a raised-grid overlay or prepare labelled card/number strips; these standard PDF/SVG files are **not** themselves Braille or raised tactile sheets. A teacher can read the complete instructions below and record a learner's exact words through AAC/sign/scribe. Source numbers remain [in the learner data](../STUDENT-DATA.md).

## [Game-map scatterplot frame](scatterplot-frame.pdf) · [SVG](scatterplot-frame.svg)

Title “GAME-MAP SCATTERPLOT”. Subtitle: “Source G · nine fictional drafts · rooms against clue icons.” Blank graph. Horizontal axis **Number of rooms (0–5)** at integers 0,1,2,3,4,5. Vertical axis **Clue icons (0–25)** marked 0,5,10,15,20,25. Footer: “Two drafts may share the same x. Label each point and name the source.” No data points are plotted. **Nonvisual:** read each draft as `(rooms, clue icons)`, arrange x-labelled stacks with y-number tiles; report direction, form and unusual value in text or speech.

## [Residual ruler](residual-ruler.pdf) · [SVG](residual-ruler.svg)

Title “RESIDUAL RULER”. Instruction: “Complete model and signed gap for each invented draft. Units: clue icons.” Columns: Draft; Rooms x; Listed y; `M(x)=3x+2`; `y − M(x)`. The last two columns are blank. Rows: A 1/5, B 1/6, C 2/8, D 2/9, E 3/11, F 3/12, G 4/14, H 4/15, I 5/22. Footer: “A residual is a numerical difference, not an explanation of its cause.” **Nonvisual:** compare listed and model tiles in that order, then name the sign and icon unit.

## [Two-way grid](two-way-grid.pdf) · [SVG](two-way-grid.svg)

Title “TWO-WAY TABLE”. Instruction: “Source C · 50 fictional designs · fill the cells and margins.” Blank matrix rows **Puzzle**, **Story**, **No theme assigned**, **All designs**; columns **Two-sided**, **One-sided**, **Total**. Footer: “Check every margin twice: row totals → grand total and column totals → grand total.” **Nonvisual:** build four labelled row mats with two cell slots and total slot, then count down two columns. Keep “No theme assigned” in the full register.

## [Category claim audit](claim-audit.pdf) · [SVG](claim-audit.svg)

Title “CATEGORY CLAIM AUDIT”. Four large panels in reading order: **CLAIM + SOURCE:** “Who counted what? Which exact words overreach?” **REFERENCE GROUP:** “Numerator ____ of denominator ____ given ____.” **EXCLUDED OR UNASSIGNED:** “What still has a known second-variable value?” **REPAIR + LIMIT:** “Write a scoped replacement and a missing method detail.” **Nonvisual:** move four named cards in that order; require the group's name aloud with each fraction.

All source examples are invented. The public checks and teacher-targeted key are separate files but not access-controlled.
