Last year (4yo) DD brought home a reading book and worksheet each week. We were expected to read the reading book and note it down but the worksheets were pretty much so the parents could see what they had been doing in class.
This year (5yo) she has a reading book which we are expected to read and then homework. Again it's supposed to be done with the parent. IMO there is quite a lot and we very rarely do all of it. We still take a lot of it to be letting us know what DD has been doing that week.
I will not struggle to get DD to do homework, in those cases where she has really objkected we've noted this down in her book. Her teacher appreciates this so she knows it has been an issue rather than just not looked at.
I HATE that children this young are getting homework, I hate a lot of the work set and think that it is homework or me most of the time. For example a couple of weeks ago she had to write a act booklet about Uruguay. I don't know many 5 yos able to research a country and then write a booklet about it. That one had me complaining to the school.
FWIW we are in the UK where children are expected to start school the year they are 5. Since my DDs birthday is in August this meant she was only just 4
