Target: evaluate three overstatements using cards A–F, pairing each correction with the evidence it needs. Prepare: model boundary mat and comparison mat.
- Launch · 2 min. Read “No label, so no nucleus.” Ask which model label would decide whether this is warranted.
- Model · 4 min. Revise it to “In the incomplete sketch a nucleus is not shown, so classification needs more information.” Underline the difference between drawing evidence and cell evidence.
- Guided reading · 5 min. Test “Every plant cell contains chloroplasts” and “All proteins go through Golgi.” Use Card C's specific jobs and route limitation to narrow each.
- Practice route · 7 min. Choose Day 9 route; make a three-claim audit: original wording, correction, card detail and what remains open.
- Audit · 4 min. Partner checks if each correction still uses
all/never/onlywithout support; learner changes it if necessary. - Exit · 3 min. “Which one sentence would you put beside a teaching diagram?” Accept a source-backed limitation, not a claim that the picture is real microscopy.
