Greater-than signs were read and drawn correctly every time, two signs in one line was opened and applied unaided, and the mixed set ran in full, 6 of 6 right. Ran 09:18-10:30 on the Tuesday interleaved-practice block after the 09:00 warm-up; non-calc; typed, nine drawings on paper by photo; one item per message; chunks to 09:38, 10:03 and 10:30, breaks 09:38-09:45 and 10:03-10:06. Owed from 12 Oct: 0 or 9 for x greater than 2 answered 9; 9 bigger than 2; the redraw had an open ring at 2 and 6 circled but arrowheads at both ends of the axis; asked left or right she sent a new drawing with a separate arrow going right. Sorts 4 of 4 in 2 min. Signs in words from two choices 4 of 4. Number lines, no hints: x at least 4, x greater than 1, x less than 8, x greater than 5, all right, 1 to 4 min each, strict rings left empty; a fitting number marked on 1 of 4. New: 2 at most x less than 6 built with four questions (4 of 4), picture shown, confirm 2 of 2, then unaided on paper -1 at most x less than 3 and 0 less than x at most 4, 2 of 2; whole numbers for the second listed 1, 2, 3, 4. Mixed set, no topic labels: error interval for 7 cm to the nearest cm right with x written for L, then drawn right with L; rectangle x + 5 by x, perimeter 34, area 66 cm squared with units, arithmetic lines typed, no equation in x, 9 min; two inequalities read from pictures 2 of 2; 60 pounds less 15 percent gave 51 pounds via 10 percent plus 5 percent. 31 asks, 31 answered, 0 blank: 29 right first time, 2 part right. Not run: dividing by a negative. Session 95 unfinished work is completed. Homework 8 named at the open, still not handed in. The lesson review follows in a separate call because the single call returned Bad Gateway.
FIRST, cold and with no sorts: she draws x greater than 3 on paper, then names one number that fits x greater than 7 (greater than was right 5 of 5 on 13 Oct after sorts, 0 of 2 on 12 Oct). Both right: open dividing by a negative, owed since 12 Oct: minus 2x less than 6 beside number checks (does 5 fit, does minus 5 fit), she writes each line, two confirms with hints, then four on her own, each drawn on a number line. Do not tell the flip as a rule before she has tested numbers. Number lines and two signs in one line are done (4 of 4 and 2 of 2 unaided on 13 Oct): do not re-set them beyond the cold check. Then listing whole numbers after solving. For later: an equation in x as the first line on a perimeter item (A21); a multiplier in a money question (N11-N12); polygon sides (G3); subject twice (A5). In an error interval, watch that the question letter is used. Homework 8 (straight lines, due 11 Oct) is still not handed in.
Dividing by a negative in inequalities not opened (planned since 12 Oct). Everything else owed from 12 Oct is done: the 0 or 9 check, the redraw, four number lines, the error-interval link.
| Topic | Name | Change | Evidence recorded |
|---|---|---|---|
| A22 | Developing → Developing | 13 Oct, non-calc. Number lines (taught 12 Oct) applied 4/4 unaided on paper, no hints: x at least 4, x greater than 1, x less than 8, x greater than 5; strict rings left empty, arrows the right way 4/4. Sorts 4/4 and signs in words 4/4 first time; 0 or 9 for x greater than 2 answered 9. Two signs in one line: taught, confirmed 2/2, applied 2/2 unaided on paper; read from a picture 2/2; integers listed 1/1. Dividing by a negative untaught. Proposed secure, for adjudication. | |
| N15 | Secure → Secure | 13 Oct mixed set, cold, non-calc, no cue: pencil 7 cm to the nearest cm, length L: wrote 6.5 at most x less than 7.5, bounds and both signs right, letter x not L, 4 min, 1/1 unaided. Then drew it on paper with L: filled circle at 6.5, open ring at 7.5, joined. Fifth clean error interval; first one drawn on a number line. | |
| A21 | Secure → Secure | 13 Oct mixed set, non-calc, untimed, unaided, worded show your working and state the units: rectangle x + 5 by x, perimeter 34, area asked. Typed 5 x 2 = 10, 34 - 10 = 24, 24/4 = 6, x = 6, 6 + 5 = 11, 11 x 6 = 66, area 66 cm squared, with an answer sentence. Right, 9 min, 0 hints. Arithmetic route: no equation in x written. The 7 Oct timed version was answered skip. | |
| N11-N12 | Developing → Developing | 13 Oct mixed set, non-calc, unaided, worded show your working: 60 pounds reduced by 15 percent. Typed 60/10 = 6, 6/2 = 3, 3 + 6 = 9, 60 - 9 = 51, with an answer sentence and the pound sign. Right, 5 min, 1/1. Built from 10 percent and 5 percent, no multiplier used; one line ran 3 + 6 = 9 = 15 for 9 is 15 percent. Third separate day right (9 and 10 Oct multipliers). Proposed secure stands, for adjudication. |
