I totally agree on the younger ones needing constant input from someone.
My P1 was apparently at the "top" of the "early" curriculum for number and social and at the "top" of "first" for reading and writing in her report last term. She's still needy as hell and can flip to tears and tantrums if she gets a question wrong on an app or she thinks a game might be too hard...
I mean she's probably less prone to tantrums in school but as we moved from England having done a year of school nursery and 2 terms of reception she's had about as much school experience as a P2, so would probably be at the mature and confident end of the P1 spectrum.
She's not ready to "work" without me or another adult sat next to her, keeping her vaguely on task and checking she's read the question rather than guessed it...
Only a very few P1s will be fluent readers able to read all the instructions themselves.
There's also a task most days that requires adult involvement - making twig boats, bug hotels, nature walks, catch, random baking or science stuff in the guise of family learning (definitely things I would have preferred to keep at school - we were trying to ease her out of the need to bring random previous bits of "nature" home, and now we have to for school!!!!)
