The Practice And Research Of Mathematics Fraction Teaching In Primary School

Mathematical knowledge is a huge system.Numbers in primary school mathematics are mainly integers,fractions and decimals.Fractions are not only the most difficult but also the most important content in primary school mathematics.The teaching of fraction is the most basic and core content in primary school mathematics.Therefore,it is of great practical significance to understand and improve the current situation of fraction teaching.Based on the teaching practice for many years,aiming at the four contents of "the concept of score","the nature of fraction","the calculation of fraction" and "the application of fraction",the author studies on the basis of the compulsory education mathematics curriculum standard(2011 Edition)and the compulsory education curriculum standard experimental textbook mathematics published by Jiangsu Education Press.First of all,using the literature research method,consulting the relevant literature and books at home and abroad,it is found that the research of fraction mainly includes the development of fraction,fraction teaching,fraction learning and other aspects,which provide theoretical basis and important reference for this paper.Secondly,using the method of investigation and research to investigate the current situation of teachers' fraction teaching level and the main existing problems,it is concluded that the current teachers' fraction knowledge reserve is only limited to textbooks,lack of independent learning,and no initiative to supplement the extracurricular mathematics professional knowledge.The teaching level of teachers' fraction knowledge is general,and there are many conclusions that need to be improved and worked hard.This paper uses the test method to test the current situation and main problems of students' learning of fraction knowledge.It is found that some students are fuzzy about the concept of fraction,can not grasp the essence of fraction operation,and can not flexibly use fraction knowledge to solve fraction application problems.Third,combined with the above-mentioned problems of teachers' fraction teaching,students' fraction learning and my teaching practice,the paper puts forward the following suggestions:understanding the concept of fraction from multiple perspectives,combining with the actual perception of fraction operation and flexible use of a variety of methods to solve the problem of fraction application;around the concept of fraction,fraction operation and s fraction application,I give the teaching application,and the teaching effect reflects that the teaching strategy has a certain effect.
