Achieving meaningful educational outcomes requires scalable strategies for mastering mathematical concepts and skills, with student engagement at the core. This paper examines the use of comprehensive, technology-enhanced activities designed to promote active learning and deeper conceptual understanding. Specifically, it focuses on the integration of Desmos, an online graphing calculator, into mathematics instruction. The study explores whether combining Desmos with a hands-on approach to teaching trigonometric functions helps students connect abstract concepts to real-world applications. Findings underscore the effectiveness of digital tools like Desmos in increasing student engagement and improving student performance--particularly in the context of graphing and interpreting trigonometric functions.
