Of course 11 year olds should be able to punctuate accurately and know the main parts of speech (nouns, verbs, etc), but they really do NOT need to know the terminology for a subordinating conjunction, the past progressive, the subjunctive, etc
I agree with that daphnedil, well said.
And I also agree with the following from LullyDully
I am wondering what messages are being sent to children if they say they were ill when they were dancing amid the bluebells on a sunny day.
Also there is a photo of children carrying no to sats banners....not sure I approve of using children to fight an adult battle. What will be the lasting effect on their attitudes to school and exams?
And what happens to a conscientious child who didn't go to school because they were ill? (vomiting profusely!). DGD can't be the only one.
