Twenty worked… | Foundation Digital Tech · T1 W5–6 · Practice Swaps

Each pair keeps that day's data operation. These are invented cards or stories, not real plant/animal observations, material-test findings or safe-device evidence. After Check means a child's first response to that day's fresh check is already saved.

Day	Worked swap 1	Worked swap 2
21	Paper museum badge 5 has a circle and border NOT SHOWN → shape known, border unknown.	Fictional stage pass 2 has triangle/dashed → both printed fields can be read.
22	Toy map badges 1,3,5 circle → group by visible shape, regardless of border.	Library game badges 2,4 triangle → group by the same shape rule.
23	Textile cards 1,4 solid → SOLID bay when rule is border.	Story tokens 2,3 dashed and 5 hidden → DASHED 2,3; CANNOT TELL 5.
24	Gallery ID 1 physical circle-solid token → matching picture → agreed code CS.	Space ID 5 physical circle with unknown tag → picture's hidden border → C? symbol, not a guess.
25	After Check: made-up ticket source circle-dotted A, triangle-plain B, circle-hidden C → by shape A/C together.	After Check: same new ticket source → by border A dotted, B plain, C cannot tell.
26	Fictional card-holder P HELD → its outcome symbol H, not proof about real cardboard.	Fictional card-holder R NOT TESTED → outcome ?, not a failed test.
27	Paper workshop question “Which held?” → P,S HELD, Q SLIPPED, R NOT TESTED.	Model theatre question “Which was tested?” → P,Q,S known outcomes; R stays untested.
28	Paper zoo display H/SL/? key → reader can interpret P/Q/R/S story marks, no real animal data.	Map desk title “Fictional holder trial” plus source row → reader can tell where marks came from.
29	Offline badge rule SHAPE → circle IDs 1,3,5, triangle 2,4 on device only if actually operated.	Paper border rule → solid 1,4; dashed 2,3; unknown 5, with K01 NOT OBSERVED.
30	After Check: invented second trial U HELD, V NOT TESTED, W SLIPPED → U known held, V unknown.	After Check: paper station X SLIPPED, Y HELD, Z NOT TESTED → preserve Z, not a real test.
