Ask them to explain it to you. Encourage your children to study with others. Children often learn more when working in groups and sharing knowledge. Try to arrange study groups between your youngsters and their friends. Use homework hotlines.
Many schools have phone numbers to call to get help with homework.
Talk to teachers. If you don't have time to visit school, phone your youngsters' teachers and leave a message. They'll call back. Ask what your children are doing right, so you can praise them, and ask for suggestions about helping your children do better. When you can, read aloud to your kids.
