| 2026-10-20 | Developing → Developing | 19 Oct: recurring decimals re-taught, say-back right in her words; independent 5/6 -> 0.8 with dot on the 3 and 3/11 -> 0.2 7 with dots, 2/2, no hints; used '...' before dots were required. | session 119 |
| 2026-10-09 | Developing → Developing | 9 Oct mixed set, non-calc, no cue, a new decimal: show that 0.7272... = 8/11 -> 'x = 0.7272r, x*100 = 100x = 72.7272r, 100x - x = 99x = 72, 72/99 = 8/11' in 2 min, unaided. 100x and 99x lines both written; 'x = 72/99' not written as its own line. Second uncued full chain (first 2 Oct); the 7 Oct timed paper lacked the 100x line (2/3). Session 90. Retrieval outcome: correct. | standalone |
| 2026-10-07 | Developing → Developing | Exam practice 7 Oct (test #7, attempt #15, timed) Q7, no cue: show 0.3636... = 4/11, she wrote 'x*100 = 100x, 100x - x = 99x = 36, 36/99 = 4/11'; 2/3. Subtraction and simplification right; the line giving 100x as a decimal and 'x =' not written. Marking only: no status change. Retrieval outcome: retry. | standalone |
| 2026-10-02 | Developing → Developing | Mixed set Q6 unaided, no cue: 'x = 0.5454r, x * 100 = 100x, 100x = 54.5454r, 100x - x = 99x = 54, 54/99 = 6/11' — 100x and 99x lines both written; 'x = 54/99' not written as its own line. | session 65 |
| 2026-09-29 | Developing → Developing | 29 Sep starter, non-calc, show that 0.8181… = 9/11 asked as 'write what 100x equals first' → 'x = 0.81, x*100 = 100x = 81.81r, 100x - x = 99x = 81, 81/99 = 9/11'. Full chain including the 100x line, first time; cue was in the question. x written without a recurring mark. | session 56 |
| 2026-09-28 | 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. | session 49 |
| 2026-09-25 | 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. | session 46 |
| 2026-09-24 | Developing → Developing | 24 Sep starter, unlabelled show-that 0.2727… = 3/11 → 'x = 0.27r, 100x - x = 99x = 27/99 = 3/11'. Lines came first (unlike 22 Sep's bare 4/11) but 100x = 27.27… omitted and 99x = 27 miswritten as 99x = 27/99. | session 43 |
| 2026-09-22 | Developing → Developing | 22 Sep starter, labelled method marks only: 0.3636… → bare '4/11' correct; on request wrote 100x = 36.3636, 100x − x = 99x, 36/99 = 4/11, omitting 99x = 36. Third correct recurring decimal, third time the method came only when asked. | session 38 |
| 2026-09-15 | Developing → Developing | 15 Sep starter, non-calc: 0.27 recurring → 3/11 correct. First working offered was "0.27 × 11 = 3/11" (not a method); when asked how she got it, produced the full method unprompted: x = 0.2727…, 100x = 27.2727…, subtract, 99x = 27, 27/99 = 3/11. Wrote the subtraction as x − 100x. Second correct recurring decimal (2 Sep 0.444… → 4/9), first two-digit repeat. | session 24 |
| 2026-09-03 | Developing → Developing | 2 Sep starter: 0.444… → 4/9 correct. First recurring-decimal question asked since it was taught on 18 Aug, so the loose end now has one correct independent answer. One question only, so no promotion. | session 3 |
