Is it children or children's art? Sketch: plaster head, large tablecloth, drawing board (wooden drawing board), easel, and some useless bottles and cans. If possible, you'd better buy a human skeleton model (a must for studying in structure sketch).

I think, if you don't understand art, you'd better not open an art major. You'd better specialize in music teaching. Art is something you can't understand. Almost all other art classes are graduates of the Academy of Fine Arts.

Painting, just started to teach myself. Sketch, color, really profound. Sketch is the basis of all painting. If you can't learn sketch well, it will be difficult to draw.
