This study examined the effects of Jigsaw IV Cooperative Learning Strategy (J4CLS) on Students’ Performance and Retention in Geometry among Secondary School Students in Zaria Metropolis. A pretest, Posttest and Post Posttest Quasi-experimental research design was used for the study. The experimental group was exposed to J4CLS while the control group was taught using Conventional Method of Teaching. Sample size of students were selected from two Senior Secondary Schools in Zaria Metropolis were used as the study sample, drawn from a population of 15 schools. The two schools selected, were pretested to find their academic status before the treatment. An Instrument was developed named Geometry Performance Test (GPT) with reliability coefficient of 0.79 using SPSS. The Concept of Geometry discussed in this study was plane geometry (2-D Geometry). The data collected were analyzed using Mean scores, Standard deviation and t-test at level of significance. There is significant difference in the mean scores of Secondary students taught 2-D Geometry concepts with J4CLS and their counterparts taught with Conventional Method of Teaching in the Metropolis. Students exposed to J4CLS performed higher than those exposed to Conventional Method of Teaching. Students exposed to J4CLS had retained 2-D Geometry concepts higher than those taught using Conventional Method of Teaching. Based on the findings, it was recommended among others that, Mathematics teachers should integrate J4CLSinto main streams of pedagogy in the teaching at Senior Secondary Schools.
