Homeworks for Childrens, ¿yes or not?

How do you think about Children from primary school must to do a lot of homeworks?
There are two groups faced  in this topic,specially the parents of such Children. Parents who are agree with that, think that if their children do a lot of homeworks from the school,they will learn more about their subjects.

Or simply if the parents don´t have time to stay with their  Children because they are working or doing housework, they prefer their children stay studying.

On the other hand,there is another group that think that children shouldn´t do many homeworks because they should learn everithing in the school and after,have free time to play,doing activities with friends,take time with their parents or something like that.

In conclusion I am agree with children have more free time after school because they need to develop like children,they need to play,to stay with their parents,watch cartoons and read some children´s books. I think in this form,children learn more things that staying at home after school doing homeworks.
