This experimental mixed method research aimed to investigate: 1) the effects of integrating conflict resolution in mathematics on students' achievement in mathematics and knowledge, behaviours, and skills in violence prevention and conflict resolution; and 2) teaching strategies that can be used for the integration. A sample of four classes was conveniently selected from two schools in Jamaica for the study. Treatments were six Mathematics lessons, for example, looking at statistics and charts related to violent incidents at their schools. Findings revealed that there are numerous teaching strategies that can be used to integrate. The integration of conflict resolution significantly increases students' achievement in Mathematics and their knowledge, behaviours and skills in violence prevention and conflict resolution.
