Late to thread but just adding our experience.
Dd is 6 and in year one in a RI school in quite a deprived area and when my ds was there and it was a GOOD school ( he's now 14 ) the amount of work is crazily different.
Dd has each week- 6 reading books, 12 spellings which are a mixture of "tricky words" and general words but not easy, recent examples are wrestle, housework, circus, school friend. Dd loves spelling and does very well as we practice a lot but given that half of her class are still 5 I think it's quite hard.
She also gets a comprehension piece, a maths piece and a topic piece of homework each week that the children have a week to complete. To clarify, the reading books are given out two at a time and changed 3 times a week.
Dd is lucky that we help with her learning and that she herself loves to learn but I know for sure there are dc in her class with parents who have little or no interest.
MN tends to swing wildly from one extreme to the other.
Our recent OFSTED inspection gave 1 day notice, we drove past her school at 9pm the night before and the car park was still full, the school have a lot to prove, the building feels small and classrooms are tight, I applaud the staff I really do but can't help but feeling my dd is being failed for various reasons and am constantly thinking about moving her.
