Abstract: The rapid iteration of digital and intelligent technologies is driving a profound transformation in basic education worldwide. The traditional lecture-based and paper-and-pencil model of mathematics teaching can no longer meet the demands of cultivating core competencies among senior high school students in the new era. Singapore's basic education has long been characterised by its competence-oriented, practice-oriented, and innovation-oriented approach. Within mathematics teaching, the deep integration of educational technology and classroom instruction constitutes a key pathway to delivering teaching tailored to individual students, overcoming entrenched teaching challenges, and nurturing students' mathematical thinking and digital literacy. Drawing on frontline teaching practice in Singaporean senior high school mathematics, this paper analyses the practical problems that currently beset digital teaching—namely the superficial application of technology, inadequate adaptation to learners' profiles, weak integration of competencies, and a singular evaluation system. It innovatively proposes a framework for digital teaching implementation built on "technology empowerment + grounding of thinking + tiered education," and explores, from four dimensions, digital and innovative teaching pathways suited to the Singaporean senior high school mathematics classroom: the reconstruction of dynamic visual teaching, personalised adaptation to learners' profiles, process-oriented digital evaluation, and the two-way enhancement of digital literacy among both teachers and students. Practice demonstrates that the precise, measured, and deep application of digital teaching can effectively resolve the difficulties of abstraction, wide variation in learners' profiles, and the challenge of putting theory into practice in senior high school mathematics, thereby raising both the efficiency and the quality of classroom teaching and providing a localised practical reference for the digital transformation of mathematics education at the basic-education stage.
