My children are all dyslexic and don't automatically know the answers to their times tables.
Didn't stop DS doing all of the statistics for his A level Sociology.
Didn't stop my daughter being able to learn about navigation when she went sailing around the British Isles for the summer
Doesn't stop any of them from managing bus and train timetables as they travel around the country independently, doing (killer)Sudoku, knowing how much interest will be paid into their bank accounts, being able to work out how much paint they needed to redecorate their bedrooms.
Look at this article about deschooling
home-education.org.uk/article-deschooling.htm
"Sometime a child may have been traumatised by their school experiences. Perhaps by bullying, or the sense of being a small cog in a large institution. Sometimes it can be specific incidents leading to school refusal that leads to the decision to home educate. In these kinds of circumstances the process of deschooling is not limited to relearning how to learn, its learning how to trust in their own safety again. In this sense its the re-establishment of the child's concept of self and individuality.
Since their education has sometimes been bound together with fear and low self esteem then attempts to introduce formal learning into the child's life too soon after a removal from school may well be met with resistance from the child. It therefore can take some time for the child to see formal education as a safe and positive thing."
We tried the same sort of thing when our children were deregistered. All that happened was we were reproducing the pressure that they had felt at school to home. Suddenly they were getting the pressure from the two people they had felt safe with and who had been building self confidence-us!
We stopped and allowed deschooling (for them and us) to happen.
It has been suggested that children need a month for every year they have been at school, to let go of it all. For my ds it took longer than that.
My suggestion
Tomorrow get up and go for a walk
Dress up warmly, put on wellies and go jump in puddles!
Look around you as you go and chat to your ds about the weather/animals you see/the trees/clouds-anything and everything you see.
Find a cafe, have a delicious treat together and giggle about the fun you are having.
Talk to him about what he wants to talk about.
Make plans for the holidays you are going to have.
Have fun!!
And then when you get home and are chilling out some more, reflect on everything that has been said and you'll see what a lot you have covered just from having fun together.
