My daughter is in school and I do help her with her homework, read to her etc, she doesn't really understand words though (we are thinking dyslexia) so we get packs home if they are struggling but on top of all that we also have reading homework, maths homework, activity sheets, a new thing called talk homework, and then projects to do plus there words to learn. for a 6 year old that is alot of homework in a week, and with a young one on my own when dh is working away it's alot to do and sometimes we don't get a chance to do anything, or are up until 8.30pm trying to get it done. When I was 6 we never really got homework, I think it puts kids off when they are learning all day then have to come home and do homework every night as well and are unwilling to learn, I know from my experience trying to get miah to do homework every night is a battle, there's sometimes tears there's tantrums.
I've kind of went off on a tangent now so ill stop and hope it makes sense lol
