That's not to say parents should ignore homework —— first, they should monitor how much homework their kids have. Thirty minutes a day in the early elementary years and an hour in grades four, five, and six is standard, says Rosemont. For junior-high students it should be “no moms than an hour and a half," and two for high-school students. If your child consistently has mom homework than this, you may want to check with other parents and then talk to the teacher about reducing assignments.
