I do make my child do all of her homework. She also has to do chores and keep her room clean. Most of those things are boring but I believe that she is learning responsibility and real life lessons. One day she will have a job and the ability to perform mundane tasks with pride will be needed.
I will also note that we do go to a magnet school and our homework is more challenging than regular school.
And as for extra worksheets.. That is usually child led, if she comes to me and asks me to show her something new or give her a work sheet, then I do.
Potty verbs... now that is funny!
