I didn't. But then I've never been able to 'do' Maths. I have the mathematical equivalent of dyslexia. DD2 has it too. It's been a struggle to understand anything mathematical! I don't think I'd get far with any KS2 paper
and I've always felt totally stupid because of my lack of understanding. My brothers teased me constantly about it and I was the butt of all the 'dimwit' jokes in the family.
I vowed I'd never do the same to my children, but I did help DD2 as much as possible and she gets by....as do I!
Anger management!!! Help needed.
