This study examined the influence of classroom environment on senior secondary school (SS1) student’s Mathematics Achievement in the Federal Capital Territory, Abuja. Quasi-experimental research design was used to test two hypotheses on the influence of two classroom variables, class size and instructional facilities on students’ academic achievement in Mathematics. A sample size 150 students was selected from public secondary schools for the study using stratified and simple random sampling procedures. MAT instruments were used for data collection and a questionnaire. The reliability was established through Kuder – Richardson K-R-21 formula which gave the reliability index of 0.78. Mean and Standard deviation were used to answer the research question while Independent t- test was the inferential statistic adopted to test the hypotheses at 0.05 level of significant. The result of the analysis revealed that class size and availability of instructional facilities significantly influenced students’ academic achievement in Mathematics among SS 1 students in Abuja. Based on these findings, the following recommendations were made among others; Government should increase funding on provision of conducive classroom environment with optimum class sizes. Instructional facilities for teaching Mathematics should be made available in public schools.
