First of all, you have to interact well with the children, and then you have to teach in a lively way when teaching painting. You have to prepare the tone, props, etc., and you have to be focused in small classes, middle classes, and large classes. The time is different. The time for drawing in small classes should not be too long. Children's attention is easily distracted. It is better for middle and large classes. You can prepare some small prizes, small stickers and the like. It is also good to use it to let the children get into trouble when they are messy. Let the children calm down and continue to draw. The things to learn to draw should not be too difficult or complicated. If you show an example, the drawing should be large and clear, and use very vivid language to describe it when drawing, so as to arouse the children's interest in learning to draw! Hope this helps you
