There are many modes of primary school mathematics teaching, 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 "characteristics" of reform, such as creativity, life-oriented, generative, cooperative, open and so on. These are the past mathematics education and teaching beyond. Under the background of new curriculum reform, the combination of self-consciousness and dialogic teaching in primary mathematics teaching will inevitably generate a new teaching mode. This paper tries to construct such a valuable teaching model, but does not exclude or deny the existing valuable mathematics teaching model and reform results, but reasonably absorb these advantages, and integrate them into the primary school mathematics dialogue teaching.
