I suggest that we open a colorful music art box. In view of the present situation and difficulties of children's art education, we have developed professional art textbooks suitable for kindergartens. The teaching mode of double main lines, that is, the combination of cognitive education and art education, is divided into three age groups: small class, middle class and large class. Each grade is divided into two semesters. The teaching topics cover eight major topics, including animals, people, plants, landscape, architecture, transportation, food and daily necessities. Art forms are divided into gouache, line drawing, printmaking, decorative painting, sandpaper painting, collage, clay sculpture, hand-made and so on. The biggest feature is that ordinary kindergarten teachers can bring out professional art works after using this set of teaching materials, without preparing lessons and materials, which makes kindergarten art classes easier. Moreover, unlike ordinary art textbooks, children are always allowed to draw the same works. Opening colorful art boxes is to release children's nature, so that each child can create works with different personalities. Kindergarten can hold large-scale art exhibitions in less than one month.
