The written angle reason appeared unprompted on both parallel-lines items, and the mixed set owed from Friday was finished to Q5 with 0 blanks, before the session stopped at her "times up" at Q6, before the exit ticket. Starter, no notes, 3/3, 0 blanks: alternate angle 58° asked "give a reason" (non-calc) → "p = 58* because alternate angles are equal" — named reason in a sentence, unprompted, first time; show that 0.6363… = 7/11 (non-calc) → "x = 0.63r, x*100, 100x - x = 99x = 63, 63/99 = 7/11" — 99x = 63 written for the first time, the 100x = 63.6363… line still absent; estimated mean, café times 8/14/6/2 (calc, working/units not mentioned) → "31.333r" bare, correct (940/30), no midpoint lines, no units, no range — fifth bare unlabelled estimated mean. Mixed set from Q2: Q2 P(green) from 0.2, 0.5 (non-calc) → "0.2 + 0.5 = 0.7, 1 - 0.7 = 0.3, so p(green) = 0.3" ✓ every line; Q3 co-interior 116° (non-calc) → "Co-interior angles add up to 180*, q = 64" ✓ reason in words, 180 − 116 line not written; Q4 3:7 fraction for Ben → 7/10 ✓; Q5 estimated mean parcels 12/15/9/4 LABELLED "show your working… answer with units" (calc) → "1*12 = 12, 3*15 = 45, 5*9 = 45, 7*4 = 28, 3.25" — all product lines, correct, NO units despite the explicit ask; Q6 vertically opposite 71° set, not attempted — stopped. 8 items set, 7 attempted, 7/7 correct unaided, 0 blanks. Session 46's set Q2–Q5 completed; Q6 and the 4-question angles exit ticket not run.
FIRST: Q6 of the mixed set — angle vertically opposite 71°, with the reason in words — then the 4-question angles exit ticket, a written reason on every answer, with "write the subtraction line" and "units" stated on the question where they apply. Starter before it, no notes: one estimated mean unlabelled but with "rough range" as a line on the block checklist (does a range or a working line appear?); show that 0.8181… = 9/11 asked as "write what 100x equals first"; one error interval. Exit 4/4 values and 4/4 reasons → angles on parallel lines secure.
Mixed set Q6 (angle vertically opposite 71°, reason required) set but not attempted; 4-question parallel-lines exit ticket not run. Next session opens on Q6, then the exit ticket with a written reason on every answer.
| Topic | Name | Change | Evidence recorded |
|---|---|---|---|
| G3 | Developing → Developing | 28 Sep, non-calc, no notes: alternate 58° → 'p = 58 because alternate angles are equal' unprompted; co-interior 116° → 'Co-interior angles add up to 180, q = 64' unprompted (subtraction line not written). 2/2 values, 2/2 named reasons in sentences — the first session with the reason written without a prompt. Exit ticket not run; stays developing. | |
| N10 | Developing → Developing | 28 Sep starter, non-calc, unlabelled show-that 0.6363… = 7/11 → 'x = 0.63r, x*100, 100x - x = 99x = 63, 63/99 = 7/11'. Correct; 99x = 63 written for the first time; 100x = 63.6363… line still missing. | |
| S4 | Secure → Secure | 28 Sep: unlabelled estimated mean café 8/14/6/2 → '31.333r' bare, correct, no lines, no units, no range (5th bare unlabelled ask). Labelled 'show your working, answer with units' parcels 12/15/9/4 → four product lines then 3.25, correct, NO units despite the ask. | |
| P4-P5 | Secure → Secure | 28 Sep, non-calc: P(green) from P(red) 0.2, P(blue) 0.5 → '0.2 + 0.5 = 0.7, 1 - 0.7 = 0.3, so p(green) = 0.3' ✓ with every line written unasked. | |
| R7-R8 | Secure → Secure | 28 Sep, non-calc: share 3:7, Ben's fraction → 7/10 ✓ unaided, 6 days after last ask. |
