This paper aimed to investigate the perceptions of mathematics teachers in Saudi Arabia regarding the STEAM (Science, Technology, Engineering, Arts, and Mathematics) approach. A sample of 350 teachers from the Eastern Province completed a 40-item survey on their STEAM perceptions and teaching requirements. Descriptive and inferential statistical analyses revealed overall positive perspectives, with 78.6% strongly agreeing that STEAM transforms classrooms into creative environments. However, just 58.4% felt it enabled active learning, and 67.4% were unsure about systemic support. Significant differences emerged based on teacher gender and qualifications, but not experience levels or stages. While largely optimistic attitudes exist toward STEAM's value, persistent resourcing, competency, and policy barriers likely impede classroom adoption. Recommendations encompass boosting investments in STEAM infrastructure, aligned teacher professional development, specialized materials and tools, and integration support across subjects. Further research incorporating mixed methods, expanded samples, and longitudinal tracking can delineate evidence-based strategies to catalyze effective STEAM adoption. The study recommended enhancing the effectiveness of the STEAM approach in education, especially in mathematics.
