I'm going to try to explain how dyscalculia affects me, but it's difficult to do so I apologise if I confuse you.
It's like my brain has a glass window in front of it that is permeable to most things, but some mathematical concepts don't get thrugh, or often get scrambled in translation. After too long, my brain actually seems to start hurting!
I can get some concepts (I just passed GCSE maths yesterday at last!) but sometimes my brain will scramble them after I do say six, and then the logic that comes back will be gobbledigook but seem sensible to me. Other times, I get a concept (this is true with algebra), but then hit a brick wall and cannot do any more.
Here are the tips that helped me, I can't guarantee they will work with your DD but worth trying:
- Short (ten minute) spurts of number work only.
Dyscalculia tires your brain out.
2)If you can't get a concept, write it instead. For example, fifteen times seven plus the square root of one equals.
Be careful not to use any symbols or anything.
It may not work for anyone else, but it got me through the stats part of A-Level Psychology.
At school, I was top set for everything but bottom set for maths, which gave me problems socially (bottom set maths meant you had to take art / pe / sciences with a completely different set of friends) and did a lot of harm to my self esteem. It also harmed my prospects, in that I actually have a talent for sciences but coldn't do straight biology as I missed out at school as the decison to allow or not allow us to take it was based on our maths ability. However, I am now going to do a degree starting in September, and using the two techniques above have finally cracked my fear (which came as a direct result of struggling) of maths and succeeded.
I hope that helps.
Clair.
