From a broad sense, any teaching activity that can effectively promote student development and effectively achieve the desired teaching results can be called “effective teaching.” “.”Effective teaching" is not only a concept, but also a set of strategies and techniques. With the gradual deepening of the new round of curriculum reform, students’ mathematics learning presents a diversified form, and the effectiveness of teaching becomes more urgent. Place before us: how teachers should change their habitual teaching methods and guide students to explore, communicate, and interact, and truly become students’ mathematics learning.
