GAPSENSE EXERCISE BOOK ANALYSIS REPORT

Joan (Year 9 / JHS1 equivalent) demonstrates solid procedural competence across most topics on this revision page: HCF, basic linear equations (one-step multiplication and division), speed/distance/time formulae, and Pythagorean theorem for finding the hypotenuse are all handled correctly. The primary area of concern is Pythagorean theorem when finding a missing leg rather than the hypotenuse. In the main right-page working, the student computes 12² + 13² = 182 - 144 = 38, which contains two errors: (1) 13² is computed as 182 instead of 169 — a squaring error on a two-digit number; (2) the formula structure appears to add the two known sides rather than subtract (suggesting possible confusion about when to add vs subtract in Pythagoras). In the pupil response self-correction, the student writes 13² = 164 (a different squaring error), suggesting the squaring of 13 is not a memorised or reliably computed fact. The √64 extraction in the pupil response is correct (if 64 were the right value), indicating square root retrieval from perfect squares is intact. The inequality listing on the right page (Q4) appears incomplete but confidence is low due to illegibility. Teacher feedback explicitly flags insufficient effort and requests corrections, consistent with the uncorrected errors visible. No clear language barrier is detected — mathematical notation and English instructions appear understood.
