Written specifications only; no actual geometry, rendering or visual acceptance is claimed. V01–V08 are adult ordinary mathematical models, V09–V16 are exact neutral held sources with32 genuinely empty response interiors, V17–V20 are four own aids with16 genuinely empty interiors. Every full alternative is written below. A future constructor must render and personally inspect every whole plane and keep staff models separate from own work.

Visuals

V01

Actual status: Written full brief only; no rendering, Browser, human access trial or visual acceptance claimed.

Format: Future original SVG; no raster or SVG has been made in this proposal. Use semantic title/desc plus full linked text alternative; body font at least 24 px except long held sources 22 px, labels 28 px, stroke 3 px, white background/black text. Keep at least 24 px clearance. Wrapping must be explicit tspans, not clipped foreignObject. Test whole plane, mobile zoom, mono print and text alternative after construction. Colour can assist but never carry sole meaning.

Full alternative: A labelled adult place-value model for fictional badges. The first parcel 612 is 600+10+2; the second 243 is 200+40+3. Joining same-unit parts gives 800+50+5=855 badges. A second path adds 200, 40 and 3 to 612, reaching 812, 852 and 855. Neither display is a learner response or real stock count.

Geometry: viewBox 0 0 1200 850. Heading(44, 54). Place-value table outer rect(44, 140, 1112, 360), 3 equal columns 370.6667 for hundreds/tens/ones. Rows y 140, 230, 320, 410, 500, labels 28 px. Row 1 values 600/10/2, row 2 values 200/40/3, row 3 combined 800/50/5; plus label outside each row and equation 855 under at(44, 570). No blocks counted individually. Separate chunk-path text at(44, 650): 612→812(+200)→852(+40)→855(+3). Label both as adult models, not own work.

Title: One total, every part

V02

Actual status: Written full brief only; no rendering, Browser, human access trial or visual acceptance claimed.

Full alternative: An adult model of 364+278 tags. Partitioning gives 500+130+12. Twelve ones rename as one ten and two ones, so 500+140+2. Fourteen tens rename as one hundred and four tens, yielding 600+40+2=642. The tag quantity remains the same through each renaming. A separate chunk check also yields 642.

Geometry: viewBox 0 0 1200 850. Three panel rectangles(44, 130, 350, 260),(424, 130, 350, 260),(804, 130, 350, 260). Panel 1 labels 500 from hundreds, 130 from tens, 12 ones. Panel 2 labels 500+140+2 after 12 ones→1 ten 2 ones. Panel 3 labels 600+40+2 after 14 tens→1 hundred 4 tens. Arrows x 402 y 260 and 782 y 260; their labels sit above, not across numbers. Equation at 44, 470. Bottom(44, 580) textchunk check 364+200+70+8=642. Every arrow explicitly names equivalent renaming, not removal.

V03

Actual status: Written full brief only; no rendering, Browser, human access trial or visual acceptance claimed.

Full alternative: An adult exact-compensation model. Fictional 398 and 267 stickers total 665. Replacing 398 with 400 adds two extra, gives 667, then removing those extra two yields 665. A separate estimate 400+300≈700 checks scale; it is not the exact total.

Geometry: viewBox 0 0 1200 850. Upper three-box row y 160 h 160, x 44 w 310, x 414 w 310, x 784 w 370. Box 1 text 398+267; Box 2 text 400+267=667 and extra 2 label; Box 3 text 667−2=665. Arrow labels add 2 and remove 2 at mid clearance. At 44, 420 separate exact equation. At 44, 550 dashed-border panel w 1112 h 180: estimate 400+300≈700, not exact.

Full alternative: An adult model for 806 labels with 247 used. It first renames 806 as 7 hundreds, 9 tens and 16 ones. Subtracting 2 hundreds, 4 tens and 7 ones leaves 5 hundreds, 5 tens and 9 ones, or 559 labels. Check 247+559=806. A count-up path from 247 to 250 to 800 to 806 adds 3+550+6=559. This is modelled remaining stock, not an observed action.

Geometry: viewBox 0 0 1200 850. Table(44, 150, 1112, 300), columns label hundreds/tens/ones. Top row 7 hundreds/9 tens/16 ones=806; subtraction row 2 hundreds/4 tens/7 ones; result row 5 hundreds/5 tens/9 ones=559. Supply text 806=700+90+16 above table, not crossing headers. Inverse check 247+559=806 at 44, 560. Bottom count-up 987 must not appear: exact path 247→250(+3)→800(+550)→806(+6), total 559 at 44, 650.

Actual status: Written full brief only; no rendering, Browser, human access trial or visual acceptance claimed.

Full alternative: A precisely scaled adult number line compares fictional poster requirements 987 and 1203 labels. Counting from 987 to 1000 adds 13, from 1000 to 1200 adds 200, and from 1200 to 1203 adds 3. The gap is 216 labels, checked by 987+216=1203. Both design requirements remain; the greater number is not a judgement about design quality.

Geometry: viewBox 0 0 1200 850. Exact number line from 980 to 1220 at x 100 to 1060, y 360, scale 4 px per label. Major labelled ticks 980, 1000, 1100, 1200, 1220; endpoint 987 at x 128, 1203 at x 992. Three bracket arcs 987→1000(x 128→180), 1000→1200(x 180→980), 1200→1203(x 980→992), labels+13,+200,+3 with leaders placed at y 200/250/300 to avoid endpoint crowding. Difference 216 text at 44, 520. Text at 44, 650 says both whole counts remain, no actual removal or better design judgement.

V06

Actual status: Written full brief only; no rendering, Browser, human access trial or visual acceptance claimed.

Full alternative: An adult part-whole model uses 725 fictional cards as the whole. The known part is 468; the further part is initially shown with a box. The separate adult key gives 257, with 468+257=725. The two bar widths are proportional to 468 and 257. This labelled adult model must not be used as a genuinely empty own aid or an unseen held source.

Geometry: viewBox 0 0 1200 850. Exact bar x 80 width 1015, y 240 h 140 representing 725 units at 1.4 px per unit. Known part width 655.2 for 468; unknown part width 359.8 for 257. Vertical divider x 735.2. Whole 725 bracket above. Unknown bar initially label□in adult prompt panel, solution 257 only in separate lower adult key panel at 44, 560; other panel shows 468+257=725.

Full alternative: Two separate adult unknown-role models. In a fictional tag record 930 start and 586 left give 344 used; 930−344=586. In a different fictional card record 175 used and 428 left give 603 start; 603−175=428. The unknown counts a used amount in the first equation and a starting amount in the second. Card and tag quantities are not combined.

Geometry: viewBox 0 0 1200 850. Two independent panels rect(44, 130, 1112, 270)and(44, 440, 1112, 270). First line 930−□=586, the starting 930 tags and left 586 tags are given; separate key used 344. Second line□−175=428, the used 175 cards and left 428 cards are given; key 603 starting cards. Panel roles start/use/left are labelled at y 200/y 510, sources never joined.

V08

Actual status: Written full brief only; no rendering, Browser, human access trial or visual acceptance claimed.

Full alternative: An adult equality model for 245+□=390+75. The known right side is 465. The missing left part is 220 because 465−245=220. Substitution gives 245+220=465 and 390+75=465. Schematic bars stand for equal whole amounts and are explicitly not to scale; the box value 220 is not the whole-side value 465.

Geometry: viewBox 0 0 1200 850. Heading(44, 54). Original equation 245+□=390+75 at 44, 150. Two equal-length schematic bars x 44/x 634, width 520, y 250 h 130; explicit SCHEMATIC NOT SCALE label, both wholes label 465. Left parts 245/220, right 390/75, labels with leaders outside bar if small. Original substitution 245+220=465 and 390+75=465 at 44, 500. Box value 220 distinct from whole 465 in text at 44, 650.

Full alternative: Complete neutral fictional source: A fictional badge cupboard has 364 badges. Another parcel supplies 278 badges of the same kind. Count each badge once. The task is to find the new total; no actual stock or delivery is claimed. Four exact own prompts, in order: 1. What does each count represent? Write a number sentence for the new total. 2. Find the total using a way you can explain or show. 3. Show why any regrouping in your way keeps the amount unchanged. If your way uses no written regrouping, describe crossing a ten or hundred. 4. Give a connected check and state what your total counts. Each response area is genuinely empty; no sample answer, equation, strategy, faint model or watermark appears inside it. Staff criteria and next lessons are separate.

Geometry: viewBox 0 0 1200 1800. Heading at(44, 54). Whole neutral source at(44, 100), max 1112 width and 240 height, 22 px font/32 leading; hard-wrap preserving exact complete text. Four prompt/body groups begin y 390, 710, 1030, 1350. Each exact prompt uses 22 px/30 leading within 100 height. Each genuinely empty response rectangle at(x 44, ygroup+115, w 1112, h 185), 3 px stroke. No interior text, model, equation, dotted guide, answer, shadow marks or instructions; labels outside. Footer y 1760 says usual communication/pause/pass/finish. Non interactive SVG does not store words; actual own HTML/paper correspondence separately required.
