Angles on parallel lines taught for the first time (video, four names written, three guided examples all correct), after a 4/4 no-notes starter that re-worked Wednesday's three slips; stopped ("times up") at Q2 of the six-question mixed set, before the exit ticket. Starter, unlabelled, working/units not mentioned, 0 blanks: show that 0.4545… = 5/11 (non-calc) → "x = 0.45r, 100x - x = 45, 45/99 = 5/11" — lines before the answer, 100x = 45.4545… line and "99x =" still omitted, but no false statement this time; estimated mean, journey times 6/11/9/4 (calc) → "18.67" bare, no midpoint lines, no units, no range; drawn L-shape 4×8 + 6×5 (calc) → "62cm2" bare, units present; 3(2x−1) = 4x+9 (non-calc) → "6x - 3 = 4x + 9, x = 6", expansion line written, collection line skipped. Teach: Corbettmaths parallel-lines video; she photographed alternate/Z equal, corresponding/F equal, co-interior/C add to 180, vertically opposite equal, and said all four back from memory. Told AQA rejects letter names. Ex1 alternate 65° → "x = 65" unaided, but the written reason was an explanation of the Z shape; exam line modelled and copied. Ex2 co-interior 112° → "180 - 112 = 68 and y = 68" unaided with the subtraction line first. Ex3 two-step 48° → redrew the diagram, filled all eight angles, wrote the 180 − 48 = 132 column, z = 132° ✓ unaided; reasons named "opposite angles and alternate angles", the straight-line reason was not stated until modelled. She flagged an overlapping arc on the tutor's first Ex3 diagram (tutor error, redrawn). Movement break taken. Mixed set: Q1 corresponding 74° → "a = 74°" ✓ with a red Z drawn on her diagram but no reason in words; Q2 (P(green) from 0.2 and 0.5) set, not attempted — stopped. Set 1 of 6 attempted, 0 blanks; exit ticket not run.
FIRST: finish the mixed set from Q2 — P(green) when P(red) = 0.2 and P(blue) = 0.5 — then four more (two parallel-lines with reasons, one estimated mean, one ratio-to-fraction), then the 4-question angles exit ticket with a written reason on every answer. Starter before it, no notes: one parallel-lines angle asked as "give a reason" (does a named reason appear in words without a prompt?), show that 0.6363… = 7/11 (is the 100x line written?), one estimated mean with units not mentioned.
Mixed practice set stopped at Q2 (P(green) from P(red) 0.2, P(blue) 0.5) with Q3–Q6 not set; 4-question parallel-lines exit ticket not run. Next session opens on Q2, the rest of the set, then the exit ticket.
| Topic | Name | Change | Evidence recorded |
|---|---|---|---|
| G3 | Gap → Developing | Taught 25 Sep from the Corbettmaths video. Four names written and said back from memory. Guided examples 3/3 correct unaided on the numbers: alternate 65°, co-interior 180−112 = 68 with the line written, two-step 48° → 132 with every angle filled on a redrawn diagram. Written reasons not yet automatic: Ex1 gave a Z-shape explanation, Ex3 omitted the straight-line reason, mixed-set Q1 drew a Z instead of writing a reason. No exit ticket. | |
| N10 | Developing → Developing | 25 Sep starter, unlabelled show-that 0.4545… = 5/11 (non-calc) → 'x = 0.45r, 100x - x = 45, 45/99 = 5/11'. Correct, lines before the answer, no false statement (unlike 24 Sep), but the 100x = 45.4545… line and '99x =' still missing. | |
| S4 | Secure → Secure | 25 Sep starter, calc, working and units not mentioned: estimated mean journey times 6/11/9/4 → '18.67' bare. Correct, but no midpoint lines, no units (minutes), no range — fourth bare unlabelled estimated mean. | |
| G14-G16 | Developing → Developing | 25 Sep starter, calc, drawn L-shape 4×8 + 6×5 → '62cm2' bare, correct, units present, no working line. | |
| A17 | Exam-ready → Exam-ready | 25 Sep starter, non-calc, unlabelled: 3(2x−1) = 4x+9 → '6x - 3 = 4x + 9, x = 6'. Correct; expansion line written, collection line skipped again. |
