Maths and Dyscalculia
Estimates (based on children) for what might be called ‘pure’ dyscalculia vary between 3% and 8% but are generally estimated at around 5/6%.
There is a big difference between a dyslexic person with numerical issues and dyscalculia.
A dyslexic student is likely to have difficulties recalling number facts, mis-reading the text or the digits that specify the question, holding all aspects of a required solution in their head or mis-copying numerical arguments from line to line etc. However, many dyslexics are very able mathematicians/physicists and engineers and often have numeracy issues. The ability to understand conceptually and the ability to work symbolically are often highly developed.
A dyscalculic student will have fundamental issues in the conceptual understanding of number and may have difficulties with anything numerical. Managing money, checking change, getting on the correct number bus and finding the room number in hall (all doors identical) are just some! Presentation by Claire Trott and Simon Drew
The Department for Education and Science (2001) defined dyscalculia as:
“A condition that affects the ability to acquire arithmetical skills. Dyscalculic learners may have difficulty understanding simple number concepts, lack an intuitive grasp of numbers, and have problems learning number facts and procedures. Even if they produce a correct answer or use a correct method, they may do so mechanically and without confidence”.
Embedded Learning Portal is good: http://rwp.qia.oxi.net/embeddedlearning/searchinteractive.cfm (search for numeracy topics by level)
http://www.skillsworkshop.org/ is another good one but it is so vast it takes a lot of searching.
MathsCentre has been set up to deliver mathematics support materials, free of charge, to students, lecturers and everyone looking for post-16 maths help. The mathcentre team are a group of people who run university mathematics support centres, who teach mathematics, and who design new media products for learning.
