     Homework is a great way for kids to develop independent, lifelong learning skills, so here are some general
homework tips for parents:
     ● Make sure your child has a quiet, well-lit place to do homework.
     Avoid having your child do homework with the television on or in places with other distractions, such as
people coming and going.
     ● Make sure the materials your child needs, such as some paper, pencils and a dictionary, are available.
     Ask your child if special materials will be needed for some projects and get them in advance.
     ● Help your child with time management. 
     Establish a set time each day for doing homework. Don't let your child leave homework until just before
bedtime. Think about using a weekend morning or afternoon for working on big projects, especially if the
project involves getting together with classmates.
     ● Be positive about homework.
     Tell your child how important school is. The attitude you express about homework will be the attitude
your child acquires.
     ● When your child asks for help, provide guidance, not answers. 
     Giving answers means your child will not learn the material. Too much help teaches your child that when
the going gets rough, someone will do the work for him or her. 
     Cooperation with the teacher. It shows your child that the school and home are a team. Follow the
directions given by the teacher.
     ● Reward progress in homework. 
     If your child has been successful in homework completion and is working hard, celebrate that success
with a special even (e.g. pizza, a walk, a trip to the park) to reinforce the positive effort.
