Books that Can Be Turned into Yoga
I have basic Yoga Kids Training, and I practice yoga a few times a week. There are various books that adapt nicely to stories that incorporate yoga forms into them. These can get kids to move through the postures who don't have the focus for the meditative quality of yoga.
This book uses dog, cat, and cow, but also a yoga pushup that you call a piggie pushup and a prayer squat with duck arms you call duck.
This one uses cow and the same prayer squat, this time called chicken, but allows kids to either name animal poses that they know or make up their own "yoga" poses as they make up the other animals that the cow speaks to in the story (they don't get to see the book until after the game.) It works best with all the kids in a circle, so they know who gets to go next.
This game is well described in the blog I found it in.
