小学数学分数运算教学策略研究

The study on the teaching strategy of elementary mathematics grade operation-Taking a primary school in Sucheng District of Sugian as an exampleAbstract Fraction is a key and difficult point in primary school mathematics learning,it is animportant part of mathematics knowledge,but also a logarithmic extension of learning for pupils;Itis closely related to integer and decimal,embodies rich mathematical thinking,and plays a veryimportant role in cultivating students'sense of number.Among them,the ability of score operationhas a direct impact on other contents of students'learning,so the problem to be solved in thisstage of mathematics teaching is to improve the level of score operation of students,and the useof reasonable teaching strategies is conducive to the learning of students'score operationknowledge and the optimization of teachers'teaching effect This paper mainly uses the methodsof observation,investigation and interview to investigate the senior mathematics teachers and fifthand sixth grade students of a primary school in sucheng district of suqian.The research resultsshow that the teaching process of teachers is rough and simple,the teaching content of fractioncalculation has little connection with real life,teachers lack of penetration of mathematical thinkingand method,and students have high error rate of fraction calculation.By analyzing the problemsfound in the research and discussing the teaching effects presented by different teaching practicesthe author has drawn the following teaching strategies of elementary school mathematicsfractional operation:enriching teachers'knowledge accomplishment and improving theirprofessional level;Strengthen the intuitive teaching,optimize the teaching process;Createdifferent situations,close contact with life;Lay a solid foundation and develop good mathematicalhabits.Key words the elementary school mathematics scores operation teaching strategy
