This study addresses the new approach on the teaching and learning mathematics for primary school students. This study applied the DDR Research Method consist of three phases. The primary focus is to evaluate the interface design of Mathematics for Rural Kids, a Cloud Based Learning (MARK CBL) platform. This platform is designed to enhance mathematics instruction for primary school students, particularly those in rural areas. MARK CBL exemplifies innovative cloud-based learning, leveraging technology's transformative power to offer an engaging, inclusive, and seamless learning experience. Created with the modern learner in mind, it offers a variety of features and capabilities that enhance accessibility, effectiveness, and enjoyment of learning. With its focus on mathematics, MARK CBL provides teachers and students with abundant resources, promoting a dynamic learning environment. A survey was conducted among 368 students and 46 teachers actively involved in the MARK tuition program funded by Maybank. The results revealed overwhelmingly positive feedback from participants. In conclusion, this study underscores the vital role of cloud-based learning in advancing mathematics education within the context of Education 4.0.
