Answer:
Currently, I am homeschooled, but I used to go to a public school. What my old school used to do was that they would hang art projects across the walls of the school and have teachers hang up their favorite student drawlings on there personal locker (which all the students could see). Also if during a rainy day (for recess), They would pass around coloring boxes to each one of us, if we had already not picked an activity. Also, we had a lot of funding for our art department in which students could go in and sign up after school (I was one of them).
Hope this helps! :)
