Quasi-experimental research design was adopted. A total of 113 pupils from two public primary schools were involved in the study. The two schools were selected using simple random sampling technique. Mathematics Achievement Test (MAT), Jigsaw IV Instructional Guide (JIG), and Conventional Instructional Guide (CIG) were used for data gathering. They were all validated. MAT was tested for reliability (r= 0.78) using test retest method. Two hypotheses were formulated and tested with Analysis of Covariance (ANCOVA) at 0.05 level of significance. The findings of the study revealed that treatment had significant effect on pupils' academic achievement in mathematics (F (1; 108) = 270.332; p < 0.05). Furthermore, it was revealed that there was no significant interaction effect of treatment and gender on pupils' academic achievement in mathematics (F (1; 108) = .793; p < 0.05). Based on the findings, it was concluded that Jigsaw IV instructional strategy can improve academic achievement of pupils in mathematics. Based on the conclusion, it was recommended that teachers should be trained on Jigsaw IV instructional strategy.
