Monitor Television Viewing.American children on average spend far more time watching television than they do completing homework. In many homes, more homework gets done when television time is limited. Once you and your child have worked out a homework schedule, take time to discuss how much television and what programs she can watch. It's worth noting that television can be a learning tool. Look for programs that relate to what your child is studying in school, such as programs on history or science or dramatizations of children's literature. When you can, watch shows with your child, discuss them, and encourage follow-up activities such as reading or a trip to the museum.
