Do we think this is GCSE-level stuff...?
I was Isabelle's age only 3 years ago. We were writing 1500-word essays, expected to use academic language, and doing footnotes in History. I distinctly remember being required to find, read, and understand multiple Jstor (university-level) journal articles about Northern Irish poetry, in our own time. And in Mathematics we were starting Calculus and Logarithms (means always using scientific calculators).
This required a private, quiet workspace that was meticulously organised and stayed the same every day. We students were old enough to chose our own homework hours according to our assessment schedule, and would regularly work late into the night IN OUR OWN PERSONAL SPACES. It would have been my worst nightmare to be stuck in cramped conditions with young and infant children, following their schedule. Not to mention breaking your back over a kiddie table. Or doing babyish cartoonish worksheets that are seriously appropriate for a 7 year old. That would be so mentally unstimulating.
