Other than looking at the child's behavior, setting a good example as a parent is also important, especially when the child is young. If you set certain time for homework, make sure you are sitting there doing some work also.

In order to focus properly, it is better to have a proper place for reading and writing. Place the study table away from TV or noise coming from the living room. Otherwise, make sure the TV is not turned on when it is homework time. This will help the child to learn better.
