There are many modes of mathematics teaching in primary school, such as trial teaching, situational teaching, inquiry teaching, open teaching and so on. Over the years, these teaching modes have acquired many new and valuable reform "characteristics", such as creativity, life-oriented, generative, cooperative, open and other characteristics. These are the transcendence of previous mathematics education and teaching. In the context of the new curriculum reform, the combination of self-consciousness and dialogue teaching in primary school mathematics teaching will inevitably generate a new teaching mode. This paper attempts to construct this valuable teaching mode, but does not exclude or deny these existing valuable mathematics teaching modes and reform achievements, but reasonably absorb these advantages and integrate them into the mathematics dialogue teaching in primary schools.
