Maybe your schools are stuck in the 15th century in that London town...
....but both my kids, primary and middle (yes we still use the better system), have much of their homework via the schools online portal.
This may come as a surprise, but times have moved on from chalk boards.
The access they have to resources shames that of our mulit-million Pound company. No need for crappy plugins, runs on Apple, Android, Windows, Linux and Chromebooks.
From their they get access to much of the work they have done in the classroom, library books and other resources. The work they do is far more engaging than a tatty torn book with half the pages missing.
Yes, i'm sure some parents are blaming internet speeds (but of course we don't know how loaded the questions were) and YouTube can be a source of education (lost count how many times I've used it to fix everything from a machine machine to a complex bit of IT kit).
And maybe, in rural areas, their schools rely less on the IT infrastructure.....
