Research On The Application Of The Combination Of Numbers And Shapes In Mathematics Teaching In The Fourth Grade Of Primary Schools ——Taking A Primary School In Wuxi City As An Example

The combination of numbers and shapes is the idea of combining abstraction and images to solve problems,which serves as a bridge between "numbers" and "forms" and is an important support for students to analyze,understand,and solve problems...To understand the current state of application of number and shape combinations in the field of elementary school in my country,why analyze in combination with the actual application of number and shape combinations in the 4th grade of Wuxi A Elementary School,And it tries to propose an effective application strategy.This article provides a preliminary understanding of teacher application by creating relevant questionnaires on the application of number and shape combinations in 4th grade mathematics education.Teachers recognize the importance of the combination of numbers and shapes and do it in the classroom,but there are still some problems.Teachers have a one-sided understanding of the combination of numbers and shapes,and there are many problems in teaching.Inconsistent knowledge and behavioral phenomena are problematic in the choice of application content,in addition to neglecting to include mathematical ideas in educational purposes when preparing for lessons.At the same time,in real lessons,the timing of applying the combination of numbers and shapes is not accurate,and the appraisal of the student's application of thinking is inadequate.The main reasons for these problems are the lack of theoretical knowledge of teachers,the lack of research and excavation of teaching materials,and the lack of teaching experience of teachers.The following strategies are proposed in order to enhance the effect of the combination of numbers and shapes on education.First,the school establishes a research group to reasonably reduce the burden on teachers.At the same time,teachers themselves need to learn from classic examples and analyze their benefits.Second,we accept students as the subject to enhance theoretical knowledge,raise awareness of application,and realize the application of combinations of numbers and shapes.Third,we emphasize the educational goal of combining thoughts and methods with numbers and shapes.Fourth,familiarize yourself with the teaching materials and understand the contents of the teaching materials.Fifth,clarify the relationship between "number and shape" and investigate the timing of application.Sixth,in order to effectively carry out educational evaluation,the evaluation contents and multiple evaluation methods will be enhanced.
