The right amount of homework depends on the age and skills of the child.
National organizations of parents and teachers suggest that children in kindergarten through second grade can benefit from 10 to 20 minutes of homework each school day. In third through sixth grades, children can benefit from 30 to 60 minutes a school day. In seventh through ninth grades, students can benefit from spending more time on homework and the amount may vary from night to night.
Amounts that vary from these guidelines are fine for some children and in some situations. For example, because reading at home is especially important for children, reading assignments might push the time on homework a bit beyond the amounts suggested here.
If you are concerned that your child has either too much or too little homework, talk with his teacher and learn about her homework policies.
