Combining quantitative relationship with spatial form to analyze and solve problems is the idea of combining numbers with shapes. The combination of numbers and shapes is an effective way to solve mathematical problems for senior primary school students, and the idea of combining numbers and shapes is particularly important for students' mathematics learning. The feasible method of combining numbers and shapes: teachers need to adopt intuitive teaching to show the mathematics content to students in vivid graphics or animation forms to stimulate students' interest in learning; Visualize, visualize and simplify the complex quantitative relationship in a graphic way.
