Learning mathematics and drawing are the most basic mathematical skills and a problem-solving strategy. The advantages of mathematical graphics are: intuitive image, simplifying the complex, visualizing and simplifying many abstract mathematical concepts, calculations and quantitative relations through drawing, giving people intuitive enlightenment. Here are five basic drawing methods:

Using the drawing strategy to solve problems and drawing the figures mentioned in the questions can make up for the lack of our imagination and make the questions clearer, more intuitive, clearer and easier to understand and answer. Some students can't figure out how to use drawing to analyze and solve problems unless they are awakened by the teacher, which shows that drawing is not regarded as a means to solve problems, and there is no idea of combining numbers with shapes. For example, the simplest drawing is to add auxiliary lines, which will help students understand the meaning of the question and clear their minds.

Ruler drawing can improve students' geometric language expression ability. Through painting, students' drawing ability and practical ability can be cultivated. At the same time, students can experience the simplicity and rigor of mathematical language and the unity of mathematical drawing language and graphics in the process of mathematics learning.
