Closed Tuesday's two cut lines and ran a 4-item no-notes starter (4/4 correct, 0 blanks); stopped ("times up") at the start of chunk 2, before angles on parallel lines was taught. Cut lines: trapezium 8, 12, h 5 — first answered by moving a triangle to make a 10×5 rectangle → "50cm2" ✓ with no formula; said "i don't know the formula"; after "where did your 10 come from?" wrote "12 + 8 = 20, 20/2 = 10", then, given A = ½(a+b)h, wrote "A = 1/2(8 + 12)5 = 50cm2" ✓. Median group, homework table 5/12/8/5 → "5 + 12 + 8 + 5 = 30, 30/2 = 15, 5 + 12 = 17, so the median is 20 < t <= 40" ✓ running total written first, unprompted. Starter (unlabelled, no mention of working or units): show that 0.2727… = 3/11 (non-calc) → "x = 0.27r, 100x - x = 99x = 27/99 = 3/11" — lines came first, 100x = 27.27… line omitted, 99x = 27 written as 99x = 27/99; L-shape 5×9 + 7×4 (calc) → "73cm2" ✓ bare; estimated mean, parcels 4/9/5/2 kg (calc) → "3.5" ✓ bare, no working, no units, no sense-check; inequality on number line, open −2, filled 3 (non-calc) → "-2 < x <= 3" ✓. Movement break taken. Chunk 2: Corbettmaths parallel-lines video assigned with the task of writing the three names; stopped before reporting back.
FIRST: angles on parallel lines, not yet taught — reopen the Corbettmaths parallel-lines video, she writes the three names (alternate, corresponding, co-interior) and equal/180°, says them back, then 2–3 examples she does step by step, an interleaved set with one averages and one probability item, and a 4-question exit ticket with reasons in proper wording. Starter before it, no notes, working and units NOT mentioned: an estimated mean on a fresh table (does a midpoint line and units appear?), show that 0.4545… = 5/11 (is the 100x line written?), a drawn L-shape area (is a working line written?).
Angles on parallel lines not taught: the Corbettmaths video was assigned (write down the three names, equal or add to 180°) and she stopped before reporting back. Open on that video, then examples, practice and the 4-question exit ticket.
| Topic | Name | Change | Evidence recorded |
|---|---|---|---|
| G14-G16 | Developing → Developing | 24 Sep: trapezium 8,12,h5 → 50cm² by rearranging to a rectangle; formula line only after 'where did your 10 come from?' then 'A = 1/2(8 + 12)5 = 50cm2' ✓. Starter L-shape 5×9 + 7×4 → '73cm2' ✓ bare, units present. | |
| S4 | Secure → Secure | 24 Sep: median group from 5/12/8/5 table with running total 5+12=17 written first ✓ (closes Tuesday's cut line). Starter estimated mean, parcels 4/9/5/2 kg → '3.5' ✓ bare: no midpoint lines, no units, no sense-check. | |
| N10 | 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. | |
| A22 | Developing → Developing | 24 Sep starter, number line open −2 to filled 3 → '-2 < x <= 3' ✓ unaided, circles read correctly. Topic still not formally taught. |
