These cards offer illustrations on one side and instructions on the other. The cards are very well-made. The pictures are beautiful and the descriptions are clear and child friendly. These yoga poses do not seem to be religiously-based but rather introduce mindfulness, stretching, and relaxation regardless of personal belief system. These are great! I would say they are ideal for ages 3-12. If the child cannot read yet, a grown up can read the instructions on the card aloud.
