Teaching the procedure
With your involvement, your child will be in a much better position to write an effective draft. Yes, it does take time to do this, but it is time well spent. You are showing your child the correct planning procedure for long-term writing success, not just for this one assignment.
If you want to help your child develop better writing skills, this is the best way to start because this is where most children have difficulty. Sometimes teachers either don't have or don't allow enough time for discussion and planning; sometimes they do. With practice and your help, your child will become more engaged with writing tasks, will enjoy discussing them with you, and will produce a much higher standard of work.
