Abstract: Guided by the Singapore Primary Mathematics Curriculum Standards, this study constructs an innovative teaching model of “life scenario introduction – modeling inquiry – AI dynamic feedback – interdisciplinary transfer” by integrating the CPA (Concrete-Pictorial-Abstract) modeling approach with artificial intelligence tools. Through empirical analysis of two typical classroom cases covering fraction operation and data analysis teaching, the results verify that the proposed model effectively improves students’ modeling thinking ability (an improvement rate of 32%) and problem-solving competence (classroom participation rate reaching 95%). This research provides reusable technology integration strategies for frontline mathematics teachers and responds to Singapore’s educational vision of “Thinking Schools, Learning Nation”.
