1. Read the question and make it clear.

2. Analyze and clarify the relationship.

3, drawing, intuitively reflect the relationship.

4. Look at the picture and solve the problem in columns.

Let's talk about three ways to solve problems by drawing line segments:

Note: The problems solved by drawing line segments are generally travel problems and engineering problems, and there are also some application problems of compound fractions. Of course, there are some other types of application problems that can be solved by drawing to simplify the thinking process.

Drawing to solve application problems has different analysis methods in different types of questions. Take the travel problem as an example:

Travel problems include: distance, speed, time, these three quantities (distance may include total distance, A-line distance, B-line distance, etc. And the speed and time are the same. )

At this time, according to the meaning of the topic, there are three drawing ideas: 1, drawing a line segment according to the distance (usually a line segment), 2, drawing a line segment according to the speed (usually 1-2 line segments), and 3, drawing a line segment according to the time (usually a line segment).

Note: each drawing mode does not reflect a certain content alone, but corresponds to other content and is solved according to the formula.
