Depends on the homework. Clearly, my dining table is not the place for your plasticine and styrofoam diorama creation! But a math worksheet, or home reading, sure, if mom and dad want that to happen.
That being said, I won't check over homework or beg, plead and cajole the child to get started or finished.
And this is kind of a moot point for me anyway, as I no longer do care for older school aged kids. Just wanted to weigh in.
