Practice papers for KS1 SATs is ridiculous. I am hopping mad on your behalf! No wonder your dd is feeling stressed about it. The pressure should be on your dd's teacher, not her.
DS1 is in yr6. I haven't been told (haven't asked) what he's predicted for SATs, and he hasn't brought home any practice papers ever. They have done the odd one at school in the last half term, but they certainly don't bang on about it.
When he did KS1 SATs (and they were more formal than they are now), he didn't even know the term "SATs" and didn't realise that the "little tests" they did were anything particularly special!
