# Full source-aid alternatives

Every visible word and source relationship is available below. Read only the selected useful part; retain complete access. Paper, usual communication and adult-directed exact recording require no colour, vision, touch, printer or device. Ordinary models and held-source own aids are explicitly separate; keep keys and reserves unseen.

## model-table · A useful table: model

**Every visible word in order:**

1. A useful table: model
2. Read, draw, say, sign or direct. One useful part can be enough.
3. MODEL · Which paper game would you try? Eight fictional
4. invitations; six available choices, two unavailable replies.
5. Source list: maze, matching, maze, story, maze, matching.
6. maze: 3 recorded choices
7. matching: 2 recorded choices
8. story: 1 recorded choices
9. No available reply: 2. Their preferences/reasons stay unknown.
10. 3 + 2 + 1 = 6 choices; 6 + 2 = 8 invited records.
11. Maze is most among recorded choices, not everyone.
12. SubjectNest original model / blank · CC BY4.0 · contributors2026

**Complete geometry/meaning:** The complete fictional list appears above three separately labelled equal-width count rows: maze3, matching2, story1. A separate no-response note2 is not a fourth game category. Six choices plus two unavailable account for eight. No learner response is supplied.

**No-image route:** Read this selected full text; child chooses their own response and usual communication or directs an adult. Keep child decisions/actual mathematical reasoning distinct from supplied source facts, adult operation and hints. No required physical making, actual survey/project, learner result or broader attainment is implied. Original words/geometry CC BY4.0; system sans-serif only, no font binary.

## model-symbols · Same data, another view: model

**Every visible word in order:**

1. Same data, another view: model
2. Read, draw, say, sign or direct. One useful part can be enough.
3. MODEL · The same six replies in a different representation. One
4. outlined square means one recorded choice.
5. maze
6. matching
7. story
8. Key: one square = one available reply.
9. Two unavailable replies stay outside the game-choice display.
10. SubjectNest original model / blank · CC BY4.0 · contributors2026

**Complete geometry/meaning:** Three rows use equal-size outlined squares: maze3, matching2, story1. Text labels, count-table partner and one-square-per-reply key are complete. Two unavailable records are separate, not allocated to any row. Compare representation features; this optional aid is not full graphical-software coverage.

**No-image route:** Read this selected full text; child chooses their own response and usual communication or directs an adult. Keep child decisions/actual mathematical reasoning distinct from supplied source facts, adult operation and hints.

## model-place-value · A trade that keeps the amount: model

**Every visible word in order:**

1. A trade that keeps the amount: model
2. Read, draw, say, sign or direct. One useful part can be enough.
3. MODEL · 405 = 4 hundreds + 0 tens + 5 ones
4. 405 = 3 hundreds + 10 tens + 5 ones
5. 400 + 0 + 5 = 300 + 100 + 5
6. Trade one hundred for ten tens; keep the amount.
7. Zero means no tens in the standard form.
8. A nonstandard count can exceed 9 without changing value.
9. hundreds
10. 4
11. tens
12. 0
13. ones
14. 5
15. SubjectNest original model / blank · CC BY4.0 · contributors2026

**Complete geometry/meaning:** Two complete equations show405 standard4hundreds0tens5ones and nonstandard3hundreds10tens5ones, with equal totals. Three labelled display boxes show the standard form4,0,5. They are filled models, not empty own response areas or measured physical pieces.

## model-missing-part · How many more? A model

**Every visible word in order:**

1. How many more? A model
2. Read, draw, say, sign or direct. One useful part can be enough.
3. MODEL · Need 46 invitation slips; 18 are ready.
4. 18 + ? = 46    or    46 - 18 = 28
5. 18 → 20 (+2) → 40 (+20) → 46 (+6)
6. 2 + 20 + 6 = 28 more slips
7. Check: 18 + 28 = 46
8. The model does not tell us actual supplies or delivery.
9. SubjectNest original model / blank · CC BY4.0 · contributors2026

**Complete geometry/meaning:** A fictional46-needed/18-ready project is formulated as18+?=46 or46−18=28; counted-up jumps2,20,6 sum28more, checked by18+28. All visible equations are filled staff-supported ordinary models, not child evidence.
