I have DS1 9/ y4 (ASD, dyslexia, dyspraxia) and DS2 7/y2 (possibly dyslexic?)
They need hands on "schooling" to get anything done. Fortunately being an ex-teacher who left a few years ago because they needed more of my time and energy than teaching spared me, I can deliver that.
I'm going off piste from the work set by school as it's a struggle with resourcing, and I'm balancing the curriculum with their interests. Trying to be rigid wouldn't get us far with the children I have.
As long as they're going back to school with well-used, active brains and keeping up on their learning skills, I'm happy.
If you're balancing parenting and working, that's a major challenge, but just caring about education and showing a work ethic is a big leg up in life to begin with.
However, just viewing this as a giant holiday with no type of learning going on (reading, informative TV etc) will do children a disservice on a return to school. It will be a big adjustment anyway, and gaps will be exacerbated between the self-motivated and those that lack support. Schools don't have the resources to magically catch everyone up.
Hopefully the curriculum will be adjusted to take account of the impact of this disruption, but I'm not holding my breath! For my y2 that's not so bad as SATs haven't happened and there is lots of time before the next formal assessment points. For my y4, y5 is a foundation to ease pressure in y6. If all that is going to be condensed because of the loss of a significant chunk of y4, that puts pressure on him further down the line. While I think SATs are just a stick to beat teachers with, I do care about the pressure of the curriculum on children (indeed it was that for y2 that triggered much of our SEN investigations).
