Teach the beginning & ending as one component, not two separate ones. Target beginnings and endings as a single unit. Offer students a structure for creating beginnings and endings. One idea is to encourage them to use the same type of beginning and ending. For example, if the writing begins with action, it can end with action. If it starts with a sound effect, it can end with a sound effect. If it begins with sensory description, then it can end with sensory description.
