# Twenty optional worked domain swaps · two per Day 11–20

Every source below is **invented**, and each worked response gives a purpose-linked design idea or source correction. It does **not** report a physical result, real user response, actual school procedure or cause of movement. Use Days 15 and 20 examples **after** the fresh first responses. Optional home activity needs only spare broad paper; no purchase, personal story, real object collection or upload. A teacher records physical action/results from a real approved trial separately.

| Day | Worked swap 1 | Worked swap 2 |
| ---: | --- | --- |
| 11 | **Pretend library atlas:** a wide paper page corner is a person's proposed feature to help a reader find an edge; the question is whether someone can actually lift it safely, which has not been tested. | **Imagined art portfolio:** a big paper flap is chosen by a designer to separate two broad pages; this is an intended purpose, not evidence that a real artist preferred it. |
| 12 | **Fictional sports-kit loan:** an ASK card followed by YES or NO THANKS makes two service paths; after NO, STEP BACK is the source-consistent paper cue. No player was asked. | **Pretend music-instrument desk:** a paper question card comes before a borrow/decline card; a person arranged the order to invite a choice, but no real service response is known. |
| 13 | **Imaginary museum map table:** move a drawn pencil block away from a broad map edge to propose space for turning; only the drawing changes, not a real visitor's access. | **Pretend garden journal:** put a drawn crayon region beside, not over, the broad page edge; choose it for a planned page turn, not a claimed trial. |
| 14 | **Paper recipe book:** TOP and SIDE broad tabs are two proposed shapes; choose SIDE because a pretend reader approaches from that side, then ask if the page actually turns in a future trial. | **Toy travel map:** a broad triangular corner versus a broad straight fold are two distinct ideas; choose one to test for lifting one page, without promising that it will work. |
| 15 | **After-check only, paper theatre schedule:** one broad page may show ACT 1 while a fold covers ACT 2; two cover ideas could be a top fold or side fold, selected for the pretend reader's view. No audience result is known. | **After-check only, imaginary library choice chart:** a broad front/back paper card could show BOOK or CUP; an accordion fold is a different idea. Both remain untested proposals. |
| 16 | **Fictional game guide:** plan FOLD a broad tab, PLACE a large page, LIFT and TURN once; materials are approved paper, hands and clear table. Result stays NOT TRIED before action. | **Pretend calendar page:** compare a wide edge fold and a broad corner fold; choose one for a later one-page turn, checking that no sharp or small parts are needed. |
| 17 | **Original dance-cue sheet:** if a child actually turns one broad paper page, record TURNED; if the tab moves but page does not, record SLIPPED. No result is chosen in advance. | **Fictional bus-map page:** a safe child-directed adult turn can show the idea and a material event; note adult physical handling separately from the child's chosen tab/directions. |
| 18 | **Paper weather chart:** if a real tab slipped, propose a wider fold, retest only with approval and compare the two actual results; “wider is better” is not asserted. | **Pretend puppet script:** if a real page turned once, try a different tab position as a new question; a new reader's preference is still unknown. |
| 19 | **Imaginary library map:** directions “find broad tab → lift gently → turn one page” explain intended use; a real listener understands only if an actual observed follow-through occurs. | **Paper sports-rule page:** a large arrow on a broad tab is a human-chosen cue for a pretend reader; the sign meaning needs teaching and checking, not guessing from an icon. |
| 20 | **After-check only, table game boundary:** design a broad paper edge intended to keep a large flat paper square in a drawn play zone; record only a later actual approved material trial. | **After-check only, paper parcel mat:** a broad raised border may be a proposed way to slow a large flat paper label during a gentle table move; its effect is unknown without a safe trial. |

**Response moves:** Ask for intended user and purpose when a child names only a shape. When two ideas differ only in colour, ask what shape/position/step changes. When a child reports a proposed fold as an observed result, recode it as PREDICTION and use NOT TRIED if no action happened. When a real page slips or marker crosses a boundary, preserve that result and invite one revision; it is useful design information. Distinguish a child-controlled idea from adult-only physical handling.
