You would need a public place to put on a childrens’ art show that would get a lot of traffic. Divide the show into different categories such as painting, drawing, photography, colored pencil, etc. Divide the artwork by age group. After the show is judged you could hold an auction or silent auction to sell the art work. You might even get monies donated from art patrons for awards which could be considered scholarship money. The show would need a lot of advertisement. You would need to put on a reception to get people from the community involved. The Houston Livestock Show puts on a huge auction of childrens’ art work. The show gets a great amount of publicity on television, etc. and they have many businesses that come to support the auction. The child does not get all the money from the sale of their particular piece. The money is divided up with other children. Not sure about all the details. I have never been involved with that show. Your art show could be put on along with other activities or events.

I wish you luck in your search for a way to promote children art. If I can be of any more help let me know. I have a childrens’ art show online at Art For Homeschool. You might want to check it out. But the work is not for sale. Although I’m sure that someone could contact the children to ask to buy a piece.
