Investigation And Research On The Current Situation Of Number Sense Teaching Of Senior Grade In Rural Primary School

In recent years,in the primary school mathematics classroom reform,the core literacy training is more and more valued,and the number sense level is directly related to the core literacy training of students.In view of the fact that number sense has become an important factor affecting the development of primary school students,the author has designed a questionnaire and a case interview according to the six components of number sense,In this study,the senior students from three Donggang schools in the seaport area were selected to investigate the current number sense level of rural primary school students.This thesis focuses on three issues: first,the overall level of number sense of students in four grades;Second,the Comparative Study of Number Sense of students in four grades in six dimensions;Third,the same grade students in different dimensions of the sense of number.In order to know how much rural teachers know about logarithmic sense,this study conducted a questionnaire survey and an interview with teachers.The main conclusions of the study are as follows: Grade four students' number sense is rising as the grade increases;Although the four grades have different scores in 6 aspects of number sense,for each element of number sense,The level of numeracy has steadily increased,although the level of numeracy development in different elements of numeracy varies from high to low among students of the same grade,there are some common features: They are weak in the estimation factor of number,and weak in the problem-solving factor of the third,fourth and fifth grades.Through questionnaires and interviews with teachers,rural teachers are familiar with the word number sense,but lack of a deep understanding of it.Based on the conclusions of this paper,this study gives some suggestions to the mathematics teaching in primary schools: First,to integrate the mathematics classroom into the real life,so that students can feel the number;Third,teachers should improve their ability of number sense so as to cultivate students' number sense better.
