Every class, every work, involves a new painting content. Under the guidance of the teacher, the children not only learned the content of painting, but also mastered the stories, common sense, new words, picture expansion, video expansion and so on related to this lesson. Painting learning needs to accurately observe the shape and color of objects, carefully understand the structure and characteristics of objects, learn to analyze and dissect, and observe and think from the outside to the inside. And boldly imagine possible changes, open your mind wide, and you can draw successful works. The art class covers art, literature, natural science, philosophy, ethics and all kinds of common sense in life. Therefore, the art classroom can really be regarded as an interesting encyclopedia.
