# Day 128 · Change a key, keep a version ## Choose a small start Keep one. Change one. See what happens. ## Complete source Pretend bike-card collection: wheel and handlebar drawings both use BIKE. A BIKE request returns both. Its maker keeps that version, then changes the wheel key to WHEEL in another complete version. WHEEL returns its wheel drawing. No riding occurs. ## Day 128 ## Where to begin Begin with one neutrally described item/key and wanted access if choices are unfamiliar. Prior sessions are options, not guaranteed mastery; add items or a real system turn only where suitable. ## Adult reasoning for the different source PAPER has two model matches in the first; BOX narrows to the box in the second. Neither states real recycling eligibility. ## A different complete source Pretend recycling game: PAPER names plain-sheet and box drawings. Another full version changes only the box key to BOX. These are invented game labels, not Council bin rules. ## Materials Broad scrap paper/cards and thick pencil or wanted faithful helper. Adult checks safe materials and approved device access. No small loose parts, cutting, food, purchase, printer, photo, account or outdoor visit required. ## Next teaching Keep two complete paper records and change one stated key only. Try broad and narrow requests and invite either version for the chosen job. ## Notice Actual first/revised meanings and a job-related keep/change reason stay visible; a different version need not be better. ## Parent offer Read the complete source above and offer the short child start. One card or one wanted direction is enough. Let the child choose their own job/key before using the worked reasoning. Use broad paper/drawing/usual communication or a faithful helper; devices are optional. If a real tool is used, name who chose and who operated, and keep only the result actually observed. Private/pass/rest/return are available. Keep a chosen own record if wanted, without identifiers or claims of progress from one task. ## Choose a route 1. #### Id D128-R1 #### Target Actual first/revised meanings and a job-related keep/change reason stay visible; a different version need not be better. #### Words Retain a full paper/faithful record, alter one key on another copy, and show every matching entry—including two matches. 2. #### Id D128-R2 #### Target Actual first/revised meanings and a job-related keep/change reason stay visible; a different version need not be better. #### Words Explicitly choose Version1/Version2 in the later reviewed tool. Compare all eight fields/identities. Restore/replace/clear requires a named choice. 3. #### Id D128-R3 #### Target Actual first/revised meanings and a job-related keep/change reason stay visible; a different version need not be better. #### Words Direct one change through usual communication; an agreeing helper preserves both complete records and reads their results. Keeping the broad version is valid. ## Teaching steps 1. #### Title Choose a useful start #### Words Keep one. Change one. See what happens. Offer one broad item and an explicit key first if needed. Invite an own idea before showing the adult model. Read the complete original fictional source in wanted short chunks. No independent reading, exact counting, speech, colour discrimination or mouse skill is required. 2. #### Title Model one meaningful link #### Words Complete source: Pretend bike-card collection: wheel and handlebar drawings both use BIKE. A BIKE request returns both. Its maker keeps that version, then changes the wheel key to WHEEL in another complete version. WHEEL returns its wheel drawing. No riding occurs. Adult worked reasoning after the child’s first idea: A shared key can return two entries; a narrower key serves another chosen job. The broad first version is still meaningful. Show the intended item, representation, key or system job. Keep this ordinary model separate from every held source and any actual learner observation. 3. #### Title Use a different whole source together #### Words Complete different guided source: Pretend recycling game: PAPER names plain-sheet and box drawings. Another full version changes only the box key to BOX. These are invented game labels, not Council bin rules. Invite a choice/explanation before feedback. Adult worked reasoning: PAPER has two model matches in the first; BOX narrows to the box in the second. Neither states real recycling eligibility. A drawing, direction, phrase or usual-communication choice can show the target. If unfamiliar, model one step and invite a wanted new attempt. 4. #### Title Choose a route with the same purpose #### Words Use one of the three complete routes below and switch whenever useful. A helper handles locally safe materials/equipment exactly as directed and reads neutrally. Record content help and actual operator. Paper and observation remain participation without becoming running software or independent child operation. 5. #### Title Make or direct an own contribution #### Words Child start: Keep one. Change one. See what happens. Choose a harmless collection or use the full source. Keep actual own words/drawing/direction before feedback, with every own field initially blank. One entry or selected prompt may be enough. Rest, pass, private work and return are available; no public audience or identifiers are required. 6. #### Title Notice and respond with teaching #### Words Specific observation target: Actual first/revised meanings and a job-related keep/change reason stay visible; a different version need not be better. Specific next teaching: Keep two complete paper records and change one stated key only. Try broad and narrow requests and invite either version for the chosen job. Record source/date/first-or-revised contribution and actual help where appropriate. These are original formative observations, not QCAA bands, automatic learning gains or an annual certificate. Extra material is optional. ## Time Unpiloted flexible 15–25 minute offer, in short pieces. A 3–8 minute child start can be today’s whole task; no timer/speed criterion. ## Title Change a key, keep a version ## Week 26 ## Adult reasoning after an own attempt A shared key can return two entries; a narrower key serves another chosen job. The broad first version is still meaningful.
