# Optional 6–8 minute supplementary practice · two worked swaps per day

Choose one after the main lesson; Days 5/10 swaps are **after** the fresh check. All example descriptions here are **invented paper models for reasoning**. Their worked answers are about marks/text in those examples, never proof that a real object behaved that way. A teacher may substitute an actually safe local object after preflight and record the actual source/date/result instead of copying a model answer.

| Day | Worked swap A | Worked swap B | Look for / teacher move |
|---:|---|---|---|
| 1 | **Fictional library label:** a drawn broad rectangle has a short black line across its centre. **Answer:** line/rectangle are drawn; whether a real cover has a seam is unknown. Ask “Would this actual cover have that line?” | **Fictional garden-tool card:** drawing has one oval inside a large square. **Answer:** the page shows two outlines; it does not show the real tool's weight or material. | Child distinguishes described marks from a real feature and asks a checkable question. |
| 2 | **Fictional theatre cloth card:** text says “a picture of folded cloth” but no actual swatch. **Answer:** fold is drawn; felt softness is not established. | **Fictional paper parcel:** picture shows a rectangle with a dotted edge. **Answer:** dotted mark is visible on paper; tear strength is untested. | To describe actual material, supply a preflighted real source and record access/feature. |
| 3 | **Invented book-flap log:** first box “I think it may bend”; second box left blank. **Answer:** this is prediction only, result NOT TESTED. | **Invented craft sheet log:** first box “it may stay flat”; second says “adult lifted one edge; sheet curved during this try”. **Answer:** prediction differed from this reported model result; still not local data. | Child keeps before/after fields apart and does not penalise a changed idea. |
| 4 | **Fictional puppet sign:** drawing shows a large rectangle and attached oval panel; caption labels backing cardboard, panel fabric. **Answer:** caption gives claimed materials; drawing alone cannot verify them. | **Fictional transport token holder:** outlined outer tray and inner paper label. **Answer:** two parts are represented; actual hidden material/texture unknown until a source is checked. | Ask which part label came from verified preparation and which feature was actually sensed. |
| 5 | **After check only, fictional wide bookmark:** one drawn notched edge. **Answer:** notch is shown; no real bookmark was tested. | **After check only, fictional display folder:** title says “cardboard”, picture shows a curve. **Answer:** title is a source claim; no local object/date or bend observation is present. | New practice stays separate from the held source. |
| 6 | **Fictional aquarium sign:** a big oval under two short lines. **Answer:** these marks do not prove water, glass or a real aquarium. | **Fictional bus shelter plan:** a rectangle with a circle mark inside. **Answer:** circle may be symbol, print or cutout; drawing alone cannot decide. | Say MODEL CARD/DRAWING SHOWS before asking about material. |
| 7 | **Fictional map key:** ▭ means “straight edge drawn”, ◯ “curved edge drawn”. **Answer:** a curved mark beside an oval picture is consistent for the drawing, not evidence of a real object. | **Fictional art-wall record:** `?` beside an object's back. **Answer:** back not checked; `?` does not mean the back is rough or smooth. | Child explains key in words/AAC/tactile and names what is unknown. |
| 8 | **Invented sample table:** two model cards each have one straight edge drawn. **Answer:** the two pictures share that mark; no real-object pattern is evidenced. | **Invented model try table:** paper item A “bent in model”, B “did not bend in model”. **Answer:** model cases differ; no rule for all paper follows, and this is not a local test. | With real dated comparable logs, child may state a limited local pattern; otherwise insufficient evidence. |
| 9 | **Fictional museum caption:** “This diagram shows a large oval.” **Answer:** source-bounded; “the actual object is soft” would be an overclaim. | **Fictional workshop message:** “I wonder if a wide sheet will bend.” **Answer:** a question, not a tested result; show a listener which source would be needed. | Any actual listener response is logged verbatim; a teacher puppet reply is MODEL. |
| 10 | **After check only, fictional weather board:** two parallel straight lines and a small square. **Answer:** exact marks can be named; no real rain or temperature recorded. | **After check only, fictional theatre set plan:** triangle inside rectangle. **Answer:** shape/position shown; no real prop material or stability known. | Keep fresh held model's different marks and real-object source separate. |

**Home/educator extension:** Ask “What can this drawing tell us?” then, if a safe actual object is available and permitted, “What do we now observe, and how will we record that source?” The second answer must come from the actual object/date. No device, buying, child photo, family disclosure or forced touch is required.
