I believe that building a strong foundation is important for beginners, especially in a striking based art where you fight on your feet. Therefore what might be a good approach to teaching a beginner is to first teach stances and how to move in the stances. Then after that to teach kicking techniques. Finally hand techniques would be taught. By teaching stances, movement, and kicking first it helps build the legs and it helps to develop a strong base. In order to have effective hand techniques you do need a strong base so that's why I would want to develop that first.
