The origin of roller painting: As the name implies, roller painting is that someone accidentally puts the car on the paper and then passes by. Drive regularly and then draw on paper, leaving traces of wheels. Then a beautiful picture was formed. So we have formed our current wheel rolling painting. Rotation painting activities are mostly used in kindergartens. Early education, such as preschool education.

Knowledge expansion: As an art activity, the teacher's explanation should be as concise as possible, leaving enough time for children to draw. At the same time, we need to pay attention to the standardization of words. In activities, we should emphasize leaving car footprints on mountains and roads, rather than drawing them. And remind children to know how to cooperate, restrain them with realistic traffic safety, and ask them to turn slowly to avoid the car going off the track.
