This study, guided by two hypotheses, investigated how Mathematics teachers’ demographic variables could influence their instructional effectiveness in senior secondary schools in Cross River State. Ex-post facto research design was adopted for the study. Purposive sampling technique was used by the researcher, where all the members in the population were selected. The sample of the study is made up of all the 144 mathematics teachers in Cross River State, Nigeria. The questionnaire was the main instrument used for data collection. The instrument was validated by experts in Measurement and Evaluation. The reliability estimate of the instrument was established using Cronbach Alpha reliability method and reliability coefficient was found to be .78. Independent t-test and One-Way Analysis of Variance (ANOVA) were used to test the hypotheses. The .05 level of significance was used for the statistical testing of each of the hypotheses of the study. The results of the analyses indicated that gender and age significantly influence instructional effectiveness of Mathematics teachers. It was recommended that Government should organize regular seminars and workshops for all the Mathematics teachers in secondary schools, irrespective of their age or gender towards effective utilization of instructional materials and methods of teaching.
