🧮 Failure Analysis Data Clinic

Teams examine their Phase 2 test results, project-log photos, scale drawing, and calculation notes to locate the exact mismatch in arc length, sector area, radians, scale factor, circumference, area, or volume reasoning. The teacher models one short error-trace routine with a sample roundabout or organizer, then teams complete a revision plan that names the failed criterion, the likely geometric cause, and the new target measurement. Students pause for a partner check-in to compare evidence, name one academic move and one teamwork move that helped, then give feedback to 2 peers, receive feedback, and revise their plan before moving on.
