What is the main understanding of form?

The understanding of graphics is mainly the abstraction of graphics.

1, graphic introduction:

Graphics refer to many spatial shapes that can be divided by contours in two-dimensional space. Graphics are a part of space and have no spatial extensibility. They are limited and recognizable shapes. Graphics refer to vector graphics composed of external contours.

From the classification of angles to the classification of triangles and quadrangles, from observing objects to observing three-dimensional figures composed of small cubes, it is step by step.

2. Summary introduction:

Is the fundamental feature of philosophy. Without concreteness, abstraction cannot exist alone. Abstraction is the act or process of extracting one or several features of a complex object and only paying attention to other features. For example, the mind only considers the shape of the tree itself or the color of the leaves, but not their size and shape. Abstraction is the basic feature of philosophy. Abstraction is a description of things.

Understanding and application of graphics;

Understanding of graphics:

For graphics, we should not only let students have a look, but also mobilize students' various senses through specific observation, touch, comparison, measurement and other practical operations, deepen the experience of graphic characteristics from multiple dimensions, and help students establish a more complete cognition of graphics.

In teaching, teachers should also guide students to highlight the essential characteristics of graphics and establish a multi-dimensional understanding of graphic characteristics through exploration activities such as comparison, abstraction, generalization and reasoning.

Application of graphics:

The application of graphics has a rich realistic background and is widely used in the real world. Therefore, students should first discover and understand graphics from a large number of life examples, and then abstract graphics from the source of reality to realize the close connection between graphics and the real world.

At the same time, let students understand the basic characteristics of graphics and their relations under the concrete and realistic background, accumulate rich intuitive experience and activity experience, and then solve related problems in real life, and cultivate the ability of orderly thinking and solving problems.
