Problem-solving skills of moving point problem in seventh grade mathematics
Seventh grade math moving point problem solving skills: (1) Read the stem carefully (2) Grasp the moving point (3) Fixed point is the main idea.

1. The key to the moving point problem is to seek quietness in motion. Read the stem carefully and extract key information from multiple conditions. Mathematical thinking is the idea of classification, sorting out and classifying the extracted key information. The combination of numbers and shapes and the transformation of ideas, and the combination of numbers and shapes of key information make mathematical problems clear at a glance. Combining the above ideas, we can effectively solve the problem of middle school relocation.

2. The key to solving the moving point problem is to grasp the moving point. We should turn the moving point into a static point, and find the breakpoint (such as the equivalent relationship between the side length, the speed of the moving point, the angle and the given figure, etc.) ), establish the required equivalent algebra, break through the problem, find out the unknown and so on.

3. The fixed point problem is the main idea. For example, when moving at a certain speed, the position of the point can be indicated after setting the time; For example, if the function is a moving point, try to set a variable, and y can be expressed as x as far as possible. You can calculate this point as a moving point.
