Yes I agree. The finger method for the 9X table is one I have taught all my kids when I was teaching.
Some dyslexics have no problems with maths, some are dyscalculaxic (sp!!!) as well. Some dyslexics only have problems with spelling, others with reading and others with processing language, memorisation or a mixture of them.
I was only diagnosed when I was 30 during a Discriptive Linguistic course which I needed to work with minority languages in Africa. Suddenly I found I could process spelling/reading/learning language using different analytical techniques.
As a teacher I spent several years teaching in a specialist school for dsyleslexic kids. A joy.
I love learning languages now. Welsh is good but I don't hear it every day in Cardiff. SSiW got me started. I still can't remember my phone number! As to passwords!!!!!!!!
