Second SundAZe at TMA has free family fun which includes art-making activities, but their summer camp classes are really where it's at. Five and six-year olds start off learning about topics like color and movement, and, by the end of eight weeks, are mastering how to depict "People of the Southwest" and "Nocturnal Desert Dwellers." Older kids start off learning about textures and shapes, and and finish by basically taking graduate-level courses like "Architecture in the Southwest."
