GAPSENSE EXERCISE BOOK ANALYSIS REPORT

This Year 9 student (enrolled as B7 in the NaCCA system) demonstrates generally competent procedural skills across several topic areas. Algebra (solving linear equations) is a clear strength — all equation-solving problems were answered correctly. The HCF problem and Speed/Distance/Time formulae were also handled correctly. The primary area of concern is Pythagorean theorem application: the student understands the method (subtract squares to find a leg, add squares to find hypotenuse) but makes arithmetic errors when squaring two-digit numbers — specifically 13² was computed as 182 instead of 169. A secondary concern is square root recall: √64 was not correctly evaluated as 8. The inequality listing problem on the right-hand page is partially readable but suggests possible gaps in systematically identifying all integers in a range, particularly negative integers. Teacher feedback visible on the page ('This is not good enough Joan, you need to put in more effort. Correct your questions please!') confirms the teacher has already flagged quality concerns. NOTE: The prerequisite graph provided covers B6–B9 nodes but does not include a specific Pythagorean theorem node; the closest available node is B6.1.2.1 (powers and roots). The arithmetic squaring error maps most directly to B6.1.2.1 indicator B6.1.2.1.3 (index notation and powers). The inequality listing gap maps to B9.2.3.1.
