Stawicki, 12, works with his yoga group for about a half-hour. From 7:50 to 8:20 a.m., Stawicki focuses on breathing exercises and yoga poses like his favorites — the tree and the airplane.

Stawicki is one of six students from Parker Middle School’s autism support class who gather to practice yoga twice a week. The students have learned about a dozen poses, and organizers said it helps them better control their emotions.
