Answer:
Ever finished school and wanted to just lay down and take a nap or play video games but instead have tons of homework to do? Well that's one reason why I think teachers give to much homework.
My first reason is, that after sitting around all day in school kids need a break to play with there friends, take nap, play video games, or do what ever else that want. They need this to be successful and to continue wanting to learn.
Also, It creates a lot of stress for kids and sometimes there parents because some times yo can't figure out what the answer to one problem and neither can your parents. This puts a lot of stress on kids and sometimes they don't do the whole thing or leave the answer blank affecting their grades.
Finally, sometimes kids have other commitments after school like sports or appointments and can't do their homework. Some times teachers can't accept that or you can't do your homework at all.
That is why in my opinion teachers give kids to much homework.
Sorry for my bad grammar ;-;
