A Survey Of The Number Sense Of Students In The Five Grade Of Primary School

The sense of numbers is one of the core concepts that the Mathematics curriculum standard has always emphasized,and for the first time,the sense of numbers is put forward as an important learning goal in the mathematics curriculum standard of compulsory education(2001),and the importance of the mathematical curriculum standard of compulsory education,promulgated in 2011,is once again emphasized,and 10 core words are mentioned,In the first place is the sense of numbers,at the same time put forward the meaning of several senses: "The sense of numbers mainly refers to the number and quantity,quantitative relationship,calculation results estimation and other aspects of the perception." Two times in the reform of mathematics curriculum,always in the first place is the sense of numbers,the importance of digital sense in the mathematical reform has an important position,is an indispensable part of the mathematics curriculum,mathematics teachers for the cultivation of digital sense should run through the whole process of mathematics teaching in primary schools.This paper focuses on the core of the empirical study of the five-year sense of primary school,which divides the sense of numbers into "understanding the meaning and relationship of numbers","comparing the relative size of numbers","characterizing numbers in multiple ways","Developing computing Strategies",and "judging the rationality of quantity".This paper specifically studies the following questions: What is the overall level of the sense of numbers of students in the five grades of primary school? What is the specific performance of the five graders in primary school on the various elements of the sense of numbers? What is the cultivation of logarithmic sense of mathematics teachers in primary schools? On the basis of combing the literature on digital sense at home and abroad,a questionnaire survey was compiled as a research tool,the number of students in the five grade was investigated by questionnaire,and some students were interviewed,and the teachers were investigated to understand the current situation of the number of students in the five grades and the understanding of the teaching of the teachers ' sense of logarithm In this survey,this paper analyzes the overall trend of the development of the number sense of the five-year students,the specific performance of the various elements of the sense of numbers,the training of teachers on the number of students,and finally gives the targeted teaching suggestions.Through the research and analysis,the main conclusions are drawn: 1.The sense of number of students in the third grade of primary school is not ideal as a whole;2.The five-year primary school students have better understanding of the meaning and relationship of numbers,the relative size of comparative numbers,and the understanding and mastery of the meaning of scores is not good.3.The performance of the multiple characterization parts of the five graders in primary school is ideal,but the ability of students to express numbers in a variety of ways still needs to be strengthened,and the ability to understand the multiple representations of scores is poor;4.The five graders of primary school performed poorly on the rationality of developing computing strategies and judging the quantity,Especially in the real life background of the estimation problem is not ideal;5.Primary School Mathematics teachers lack the purpose and comprehensiveness of the cultivation of students ' sense of number.Aiming at the existing problems,this paper puts forward some suggestions on the cultivation of students ' sense of number: 1.According to the life situation,reasonable design of teaching content;2.Strengthening the teaching of the computational meaning of numbers and cultivating the diversity of computing skills;3.Focus on the awareness of estimation,strengthen the strategy of estimation;4.Improve the quality of teachers and improve the training methods.
