Writing takes practice, and it starts at home. Teach children to do things for themselves rather than do the work for them. Patience when children are young pays off later. Develop, with your child, a reasonable, consistent schedule of jobs around the house. List them on a calendar, day by day.
Every home needs consistent rules children can depend on.
Put a plan into action, and follow through. Set limits on TV viewing so that everyone can get work done with less background noise. Watch TV with your children and talk about what you see. Homework has to be done. Let children know that this is what you value.
