The stuff she is saying in those screenshots is just her regurgitating what she has read in home ed groups on Facebook.
My children are primary aged and as someone above said you need to challenge them in order for them to progress.
I could send my children off upstairs each day with workbooks that I know they can complete without help but with things like maths, in order for them to progress they need to be shown how to get to the next level and then need supervising and guiding through any tricky parts, that’s how you pick up on where they might be going wrong on a question and help them to correct it.
Some children do pick things up very quickly, one of my children is very gifted in certain areas(trying to be vague!) and if I just gave them work for their age they could do it with no problem but they would be bored and so I challenge them by giving harder work in that area even if I have to make the resources myself. I want them to thrive and keep progressing, not just get by.
One of my other children can find certain things more difficult to grasp so we take it slower and ensure that they have plenty of practice and a good grasp of an area and are confident with it. By being present you can see exactly which part they are struggling with and can work through things with them.
This is why I don’t understand why they don’t sit with Isla and Esme, because no matter if a child finds their work easy or hard they need either pushing or guidance to keep them progressing.
At her age, Isabelle should be able to do some work independently but she still needs input too. I have no idea why they don’t have a tutor for her?
