It is important to make learning fun especially for children. They remember more and have less resistance from within if you see them as equals.
On Saturday I showed a young kid and a young lady how to strike with an open hand. The explanation was simple to relax the arm and shoulder like a noodle and swing it through the partner. If you are held by the hair or ears you place your elbow or hand over the grab to avoid damage and than use the form to again slap the face and neck of the person holding you. I put an emphasis on moving and continuing to move and although it is not enogh to go through the idea once, I showed it from different situations and positions of the spine through movement so I hope it will stay with them.
