Most mathematics abstract concepts have difficulty teaching-learning, but it is easy to utilize appropriate teaching techniques like cooperative learning for better academic achievements. The current study aimed to examine the impact of cooperative learning on mathematics students’ academic performance in grade 5. Fifty students were employed as an experimental group. The data were collected through a developed questionnaire at two points, that is, pre-test and post-test. The test was based on subjective and objective methods that have multiple-choice questions (MCQs) covering the cognitive domain of Bloom’s Taxonomy. The MCQs were distributed among three domains with nearly equal weighting given to knowledge, understanding, and application (or problem-solving) skills. Data were analyzed through statistical methods that determined the positive impact of cooperative learning on the academic achievement of mathematics students. The involved students found it pleasant and enjoyed the learning environment. Teaching through cooperative learning is recommended as designing activities that promote group work can help students for better academic achievement.
