Mathematics situation refers to a common situation in mathematics teaching, which is conducive to solving the contradiction between the abstraction of mathematics knowledge and the concreteness of students' thinking. The specific approach is:

1. Life shows laziness in mathematics.

That is to bring students into society and nature, choose a typical mathematical scene from life as the object of students' observation, and show it clearly in front of students with the teacher's language description.

2. Demonstrate the mathematical situation in kind

That is, taking the object as the center and setting the necessary background slightly to form a whole to demonstrate a specific mathematical situation.

3. The picture reproduces the mathematical situation.

Pictures are the main means to display images. Reproducing mathematical situations with pictures is actually visualizing mathematical content. Mathematical illustrations, specially drawn wall charts, clip art and stick figures can all be used to reproduce mathematical situations.
