| The thought of "the combination of number and shape" is playing a more and more important role in mathematics.The combination of "number" and "shape" makes the perfect combination of graphics and geometry: the characteristics of geometric graphics are visual,intuitive,algebraic abstraction,and it is not easy for people to grasp the essence of the problem.The whole problem-solving process is relatively rigid,but the whole operation process is easy to grasp and easy for students to operate.Number and algebra and geometry and shape are the important contents of primary school mathematics teaching materials.In the process of learning from grade one to grade six,the content is constantly deepening,and students use this idea to study,and there will certainly be great gains in the future.In this paper,based on the actual situation of teaching,the author finds that there are many problems in teachers' application of the idea of "combination of number and shape" in the process of teaching,such as insufficient attention to the thought of combination of number and shape,one-sided understanding,great deviation in teaching content when using the thought of combination of number and shape in teaching,and the section of school that chooses to permeate this thought is too high.even many teachers are unable to carry out mathematics teaching with the idea of combination of numbers and figures.In view of the above problems,this study analyzes the reasons from the aspects of the school and the teachers themselves,and puts forward the corresponding theoretical promotion strategies: to strengthen the educational guidance to teachers to change teachers' ideas;to be familiar with the arrangement of textbooks and to grasp the idea of the combination of numbers and figures;to infiltrate teaching according to students' cognitive laws;to enhance teachers' theoretical learning and improve their ideological level;to enrich teachers' teaching experience and improve teaching efficiency. |
