In the second year of junior secondary school, students venture deeper into fundamental mathematical principles exploring more complex topics. The curriculum encompasses a broad spectrum of subjects including algebra, geometry, trigonometry, and basic statistics.
Students are introduced to advanced problem-solving techniques building upon the foundational understanding established in J.S.S.1. Practical applications of Mathematics are also underscored to demonstrate its relevance in daily life and future professions.
Overall, the Mathematics scheme of work in JSS2 endeavours to equip students with the requisite skills and knowledge to tackle increasingly complex mathematical concepts as they advance in their academic journey.
In junior secondary schools, how students are assessed in Mathematics can differ from school to school. However, typically, they are evaluated through tests or quizzes (Continuous Assessment Tests) and end-of-term exams.
Grading usually follows a scale from A to F, with A representing excellent performance, typically scoring around 70% or 80%, and F indicating failure, usually below 50% or 45%.
