Have the children stand on the side of the pool with arms out straight down at their side. Fingers should be together so as no to allow water to pass through them. This will help the children keep themselves afloat better. Arms should only move away from the sides about 45 degrees. This is mainly due to the breathing.
Arms Have the children practice their arms outside of the water first.
Arms begin straight down at sides. One arm at a time, reach arm out in front of you like you are going to shake someone's hand. Raise arm up ear. When it reaches your ear, turn hand so that your palm is facing out. Keep rotating your arm backwards, pinkie entering the water first.
