The class emblem of the fourth grade of primary school can be designed from the aspects of class culture, class characteristics and class objectives.

1. Class culture:

Each class has its own unique culture, which was created by the class members. When designing the class emblem, we can consider the core elements of class culture, such as class slogan, class belief, class tradition and so on.

For example, if the slogan of a class is unity, endeavor and innovation, then the class emblem can embody these elements, such as holding a pattern of multiple hands with one hand to show unity, a flying eagle to show endeavor, and a luminous light bulb to show innovation.

2. Class characteristics:

Each class has its own characteristics, such as some classes are more active, some classes are more literary, and some classes are more scientific. When designing the class emblem, we can consider the characteristics of the class and integrate it into the class emblem. For example, if the class is more literary, then the class emblem can adopt some artistic elements, such as brush, palette, music notation and so on.

3. Class goals:

Each class has its own goals, such as getting good grades in study, sports, literature and art. When designing the class emblem, we can consider the class objectives and integrate them into the class emblem. For example, if the class's goal is to get good grades in study, then the class emblem can adopt the pattern of a book and add an excellent word to the book to indicate that the class's learning goal is excellent grades.

Precautions for painting:

1. Maintain a good posture:

When painting, you need to sit in a comfortable chair, put your feet flat on the ground, and keep your back and neck upright. Don't bend over or lower your head, so as not to cause muscle fatigue or cervical pain.

2. Choose a suitable brush and drawing paper:

Different brushes and drawing paper will affect the drawing effect. Choosing a brush and paper that suits you can improve the efficiency and quality of painting.

3. Master basic lines and shapes:

When drawing, you need to master basic lines and shapes, such as lines, curves, circles and squares. You can practice some basic sketches or graffiti to improve your skills.

4. Pay attention to the use of color:

Color is a very important element in painting, and different colors can express different emotions and atmospheres. Attention should be paid to the collocation and application of colors to make the picture more vivid and harmonious.
