A Study On The Strategies Of Teaching Fraction Multiplication And Division Based On The Consistency Between Numbers And Operation

The consistency of numbers and operations is a new concept proposed in the "Compulsory Education Mathematics Curriculum Standards(2022 Edition)",how to skillfully apply the consistency of numbers and operations to the calculation teaching process of fraction multiplication and division,guide students to construct a holistic framework of knowledge,help students learn to connect and transfer knowledge,and continuously strengthen students’ understanding of arithmetic and improve computing ability.Achieve students’ understanding of the consistency of numbers and operations.This not only puts forward higher requirements for primary school mathematics teaching,but also puts forward major requirements and tests for front-line mathematics teachers.Based on this,this study takes the teaching of fraction multiplication and division based on the consistency of numbers and operations as the research direction,aiming to explore the teaching strategy of fraction multiplication and division based on the consistency of numbers and operations,so as to improve the effectiveness of teachers’ fraction multiplication and division teaching.Firstly,through the analysis of textbooks and learners,this study finds that there are some difficulties in the teaching of fraction multiplication and division,in order to better understand these difficulties,this study uses the questionnaire survey method to survey students and analyze the problems encountered by students in the calculation of learning fraction multiplication and division.At the same time,this study also used the interview method to conduct one-on-one interviews with front-line mathematics teachers,and analyzed the difficulties encountered by front-line mathematics teachers in teaching the computational knowledge of fraction multiplication and division,which provided an important factual basis for subsequent research.Secondly,this study analyzes excellent teaching cases.By collecting excellent teaching cases of fraction multiplication and division,analyzing and summarizing these cases,some effective teaching methods and strategies are found in the process of analyzing the cases,which provide a method reference for the teaching strategy of fraction multiplication and division based on the consistency of numbers and operations.Finally,this study proposes teaching strategies.Based on teaching surveys and case studies,this paper proposes a teaching strategy of fractional multiplication and division based on the consistency of numbers and operations,which aims to help teachers better carry out the teaching practice of fraction division and promote students’ understanding of the consistency of numbers and operations in the teaching process.
