This document summarizes a study on the impact of educational resources and secondary school students' achievement in mathematics in Lagos, Nigeria. It provides background on the importance of education and mathematics. Statistics are presented on students' poor performance on WAEC mathematics exams from 2004-2007, with over 50% scoring below credit level. The Lagos State Government has implemented programs like the Eko Project to improve education quality by providing resources like teacher training, assessment, and grants. The study will examine how instructional materials, learning enhancement resources, and teacher training as educational resources impact students' mathematics achievement, accounting for sex and age differences. Previous research shows a positive relationship between resources and academic performance.
