Research On Primary School Mathematics Integer Division Calculation Teaching

Calculation is the basis of primary school learning,and calculation teaching occupies most of the time of mathematics learning.Because of the special writing format and the relative complexity of calculation,the vertical division has become a difficult point for students in the whole operation learning.This study takes the vertical calculation of division as the theme,and makes an integrated exploration of the vertical calculation of integer division,hoping to provide theoretical and practical significance for the teaching of front-line teachers.In addition to the introduction and conclusion,this study includes four parts,as follows:In the first part,the concept of calculation teaching is defined on the basis of division,vertical calculation,calculation and algorithm.This paper expounds the value of vertical calculation from three aspects:deepening the understanding of vertical calculation of division,perceiving the charm of mathematical culture and highlighting the advantages of vertical calculation of division.Combined with the vertical teaching of division method,the relevant teaching mode and theoretical basis are put forward.The second part is the investigation and analysis of the current teaching status of integer division vertical calculation.Based on the analysis of teachers' interviews and students' wrong questions,the author thinks that there are several problems in teaching at present:the teaching objective is single and the ability cultivation is insufficient;The infiltration of theory is insufficient and the learning effect is low.The practice of mechanical repetition increases the burden of students;The computing class is boring and the students are not interested in it.The third part,in view of the existing problems in the teaching attempt to put forward the corresponding teaching strategies,including four aspects:enrich the teaching content,create interesting classroom;To establish multiple representations and to understand the mathematics deeply;Optimize the practice form and promote the internalization of knowledge;Explore the principle of calculation and guide students to reflect.Finally,Combined with the theoretical basis and teaching strategies,this paper analyzes the case of "division with remainder","division is one digit","division is one digit"(there is 0 in the middle of the quotient),and "division is two digit".
