The study aimed to uncover the effect of using the cooperative learning method on students ’academic achievement in mathematics for elementary school students in northern Israel. The study sample consisted of (130) male and female teachers in elementary school mathematics and (40) students of sixth grades in Arab schools in northern Israel, divided into two groups: an experimental group and a control group. The experimental group studied using the cooperative learning method, and the control group studied using the traditional learning method. The following research tools were used: (1) A questionnaire to examine the impact of cooperative learning on students ’academic achievement from the teachers’ perspective (2) Post-test with the experimental and control group to examine students ’achievement in the mathematics subject. The study results showed that the results of students ’academic achievement in mathematics using the cooperative learning method are better than the results of students’ academic achievement in mathematics using the traditional learning method.
