Teaching Mathematics with useof songs will be one of such methods. The study employed the pre- test, post-test, quasi experimental design. Using purposive samplingtechnique, one hundred and twenty (120) junior secondary students from two public secondary schools were selected for the sample.Three hypotheses were formulated and tested.
