GAPSENSE EXERCISE BOOK ANALYSIS REPORT

Joan (Year 9, enrolled as B7 in this system) demonstrates solid procedural competence across most topics: HCF, basic linear equations, speed/distance/time formulae, and Pythagorean theorem application for finding a hypotenuse are all handled correctly. The most significant and consistent error is in squaring 13: the student computed 13²=182 in the main working and 13²=164 in the pupil response section — two different wrong answers for the same computation across two attempts. This suggests the student does not have 13×13 memorised and is using an unreliable mental multiplication strategy (possibly multiplying 13 by an adjacent number or making a column multiplication error). This error propagates through all subsequent Pythagoras steps. A secondary concern is the inequality listing task (Q4 on RHS), where the student's answer appears incomplete, possibly omitting -3, -2, and 0. The teacher's feedback ('This is not good enough Joan, you need to put in more effort. Correct your questions please!') confirms the teacher identified errors but the pupil response section shows Joan attempted to redo the Pythagoras problem with the same underlying squaring error. NOTE: The prerequisite graph provided does not contain a specific Pythagoras theorem node; the squaring error is mapped to B6.1.2.1 (index notation and square roots) as the closest available node. An algebraic/geometric Pythagoras application node is not present in the current graph — this is flagged rather than guessed.
