Download the Senior Secondary School 1 (SS1) Unified Scheme of Work for Mathematics to serve as a guide for educators

`Home » SSS1 Scheme of Work » SSS1 Mathematics Scheme of Work`

In Nigeria, the Senior Secondary School 1 (SSS1) unified scheme of work for Mathematics aims to establish a robust understanding of key mathematical concepts and skills crucial for higher education and practical problem-solving. Students move from the Junior Secondary School’s basic arithmetic to more advanced topics.

The Lagos state unified scheme of work for Mathematics in SSS1 encompasses algebraic processes, geometry, trigonometry, and statistics. It focuses on enhancing students’ analytical thinking, logical reasoning, and the practical application of mathematical principles. The s is designed to prepare students for more complex problem-solving and further studies in fields such as science, engineering, and other disciplines that require strong quantitative abilities.

In senior secondary school 1, students are assessed in Mathematics based on the school’s prerogative. However, typically, they are evaluated through tests or quizzes (Continuous Assessment Tests) and end-of-term exams.

Grading 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%.
