Some Senior High Schools were selected from Sekondi- Takoradi Municipality for the study. The study was to create awareness of the need to develop student’s conceptual understanding as well as their thinking and problem solving skills in mathematics. Two categories of schools less endowed schools and Highly endowed schools were used in this study. Thirty-two teachers and one hundred and forty students were selected for the sample size. Analysis of Variance technique was used to analyze the data. Two hypotheses were tested while the analyses of data were presented using f– test statistic. It was revealed that factors such as: good teachers, good knowledge about the subject matter, good services provided by the teacher during his/her teaching, availability of textbooks and other learning facilities, student’s attitude towards mathematics, teacher’s motivation skills and the use of teaching and learning materials were the factors that support students’ performance in mathematics. The study has implication for policy and practice in educational sector.
