Yes it's okay to cut your precious homework assignments in half like my HG/2e DS' accommodations suggest. Yes, that means every teacher, not just "some other teacher and not me." If you could witness one of the nightly homework torture sessions you inflict on DS, you would immediately agree 1) the marginal learning is not worth the lengthy struggle and 2) you are stealing his childhood in an unpardonable way. Actually, you could probably cut everyone's homework in half and lose no real learning. It's not as beneficial as you think.
