I purchased this Yogarilla card deck because when I observed my son in school with his occupational therapist, she was using these cars with him.  I couldn't believe my eyes that my ten year old was doing yoga and actually loving it!  I ordered the cards right away and even went ahead and purchased yoga mats for both my children at home.  One thing about my daughter is, if she sees my son doing something, she wants to join in on the fun as well.  They absolutely love Yogarilla and they both come home from school asking if they can do yoga with me.  This is a beautiful card deck, very easy to use, thorough instructions on the back and Otis the gorilla on the front with each individual pose.  They are color coded for certain positions, which is great.  Super easy to use, and I highly recommend them, not just for school use, for parents as well!
