Learner prompts

Question: Can a learner audit a new repeated record and make a cautious recommendation? Kit: Check B introduced on Day 20, blank 0–3 table. 35 = 3 launch + 5 briefing + 12 independent + 10 post-collection audit + 5 close.

  1. 0–3: Remind learners the new case is fictional and does not describe room safety.
  2. 3–8: Give read-aloud, tactile values, calculator, AAC or scribe access as needed; do not tell which data row conflicts with its model.
  3. 8–20: Save first independent response before any partner or teacher content discussion.
  4. 20–30: Learner marks one fact, one prediction and one unknown after collection. The staff key targets a next move without a pass/fail identity label.
  5. 30–35: Ask for one next investigable question. Routes after collection: number strips; model table; signed/AAC explanation. Response move: rebuild the specific exponent, control or source-limit distinction in a different invented case.

Another domain: After scoring, transfer to an invented gallery-paper shade with new numbers. Home: state the difference between a repeated fictional value and a reproducible real investigation.
