Dd2 (year 1) not keen about school with substitute teacher

[oneofsuesylvesterscheerios]

Is it out of the ordinary for y1 to be expected to write instructions (quite detailed) and then have spelling corrected very closely?

We went to parents evening recently with dd2's usual teacher and saw her books. Her work was coming on nicely and we could see only key spellings being corrected. Her teacher said that, at this stage, if spellings are phonetically plausible, they tend not to correct the majority of them. This makes perfect sense to me.

But dd has a cover teacher at the moment and I'm wondering if expectations are a bit high? Dd said she'd written loads more than usual today, which is fine in a lot of ways, but the work was then returned to her with every error highlighted. Dd is very downcast about it. I think it's a bit much. Is it?

Y1 DD is a prolific writer. Some of her spelling is "interesting". How much is corrected depends a bit on what they have done at school - for example the teacher tends to correct words that they have recently been focusing on and words that are miles away from where they should be. And sometimes they have "key" words written up but DD doesn't look at the written up version and makes up her own . These get corrected.

Every error does seem a bit much - is the supply teacher maybe used to teaching an older year group?
