Yes! Teachers have standards that determine what they teach. Texas has their own set of standards for each subject. The Art TEKS are defined for each grade level and in High School, for each level of Art class. All my lessons are based on §117.302. Art, Level I.
These standards are based on the National Art Education Standards.

In the DFW Metroplex there are a lot of places you can go for free to view art. I have listed below all of the free experiences I know of, but it may have a cost for parking. If you know of other free experiences, please email me. I will continue to update this list as I learn of new experiences.
