Mathematical concepts play a crucial role as the foundation in the system of mathematical knowledge. There are issues such as superficiality, excessive presupposition, and lack of analysis of essential ideas in the current teaching of high school mathematical concepts, which necessitates a transformation in the teaching approach. The introduction of the 5E instructional model can effectively address these problems and enhance teaching outcomes. The 5E model consists of five phases: Engagement, Exploration, Explanation, Elaboration, and Evaluation, aiming to guide students to deeply understand the essence and formation process of mathematical concepts through student-centered and inquiry-based activities. This paper proposes corresponding high school mathematics concept teaching strategies for each of the five phases of the 5E instructional model: introducing teaching with examples related to daily life, stories from the history of mathematics, and reviewing existing knowledge to engage students' interest; employing various inquiry methods to guide students to actively think and explore; enabling students to independently summarize and express mathematical concepts, and to analyze the essence of the concepts; applying knowledge to real-life situations and the learning of other knowledge; and using diverse assessment methods to comprehensively evaluate students' learning outcomes.
