We must be lucky. My son is in 4th grade, and all he has ever had for homework since Kindergarten is one math sheet that has maybe 4 or 5 questions on it, that needs to be signed and turned in the next day. This is the first year that they have requested 30 minutes of reading each evening, including weekends, but that is no big deal.
Though, I sometimes get upset with the math homework they send home. My son tells me that they have never gone over any of that stuff before (I don't know if that is true or he just isn't paying attention) and we end up having to do most of it for him. That isn't helping him learn very well, IMO. I try to tell him that he needs to do it himself and if I help him too much I'll just be doing it for him, but he ends up crying and saying he doesn't know how to do it. Like yesterday it was asking the radius of a circle, and he said they have NEVER gone over that before. I had NO clue how to do that, so he had to wait for DH to come home. It gets a bit frustrating. That is one thing I will talk to his teacher about tonight at Curriculum night.
