I prefer the first approach which is the best use of the time that when busy parents do not have a lot of time to spend with their childrem is to have fun playing games or sports. Although playing games or sports does not benefit children's school work, but it will improve their healthy and positive attitude toward life. The reasons are as below.

First of all, while the children are doing sports, their mind will be thinking in which way can win this game. It will help them to get highly concentration in another way. What's more, it can help them to create a kind heart after they lose or win the match.

Secondly, playing games can help them to get relax after a whole day in a highly concentration situation. For example, watching TV, listening to music, play iPad... Each one of this can help the children to relax them self, and it won't let them felt morose for both of their parents are not home.

Last but not least, both playing games or sports can help children to build a good time management. Because, it is difficult for them to stop as soon as possible on what they are doing, especially the things that are fun and relaxible for them, even adults as well.

In conclusion, because of the thinking while they are playing, getting relax after whole day highly concentration, and helping in buliding a good time management, the best use of the time that when busy parents do not have a lot of time to spend with their children is to have fun playing games or sports.
