| 2026-10-12 | Secure → Secure | 12 Oct, session 95, non-calc, typed, diagram given (112 above the upper parallel, x above the lower parallel on the other side of the crossing line), worded give a reason for each stage: vertically opposite angles, equal; then co-interior angles (spelt co-interger) add up to 180; 180 - 112 = 68, x = 68. Value right, 2/2 reasons named unprompted, subtraction line written, 18 min. No degree sign. Rule name right 3 days after 9 Oct with no angle item before it. Retrieval outcome: correct. | standalone |
| 2026-10-09 | Secure → Secure | 9 Oct, cold, no diagram given, no notes: rule for two angles facing each other across a crossing -> handwritten (photo) with her own diagram, angles A and B marked: vertically opposite, and they are equal. First word right, equality stated unasked, 5 min, 1 day after she wrote the sentence herself on 8 Oct. No two-step or 'give reasons' item set today. Session 90. Retrieval outcome: correct. | standalone |
| 2026-10-08 | Secure → Secure | 8 Oct, cold, diagram of two crossing lines, no frame: rule given with the first word as horizontally (her spelling: horrosontely opisit angle) and no statement that the angles are equal, 3 days after a correct cold recall. Told only that the first word was wrong, she wrote vertical opposite angles, and they are equal, in 2 min. Re-asked 40 min later with no diagram: correct sentence. | session 88 |
| 2026-10-07 | Secure → Secure | Exam practice 7 Oct (test #7, attempt #15, timed) Q4: sides of a regular polygon from its interior angle: 'skip', no working, 1 min on focus. Set, not answered; 0/2. Polygon angles still not evidenced. Marking only: no status change. Retrieval outcome: incorrect (not attempted). | standalone |
| 2026-10-05 | Developing → Secure | Owed 4th exit-ticket item, no hints, non-calc: two-step 62° → x = 62, 'first use vertically opposite angle on x. Then we use corresponding angles' — 2/2 reasons correctly named unprompted. Exit ticket now 4/4 values unaided (54, 123, 124 on 2 Oct; 62 today). Rule for angles across a crossing written cold, no frame, 3 days after the correction ('veritcally opposite'). Meets the bar set on 2 Oct: 2/2 named reasons on one two-step item. | session 71 |
| 2026-10-02 | Developing → Developing | Applied, no hints on values: 5 angle items, 5 attempted, 0 blank, 5/5 values unaided (128, 55, 54, 123, 124). One-step reasons 3/3 as sentences unprompted (co-interior, alternate, corresponding). Two-step: mixed-set item 1/2 reasons (vertically opposite not written; name 'I don't know'); exit item both steps written unprompted but first named 'horizontally opposite'. Subtraction line written 3/3. | session 65 |
| 2026-09-29 | Developing → Developing | 29 Sep exit ticket, independent, non-calc: values 4/4 (63, 72, 47, 141); named reasons in sentences 3/4 unprompted (corresponding, co-interior, alternate); two-step Q4 gave 180 − 39 = 141 with no reason, 'i don't know' on the pair, straight-line rule after a narrowed hint, corresponding supplied by the tutor. Q6 vertically opposite 71° value unaided, reason on prompt. Subtraction line not written on Q2 despite the question asking. | session 56 |
| 2026-09-28 | 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. | session 49 |
| 2026-09-25 | 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. | session 46 |
