"Dyscalculia is a learning difficulty involving the most basic aspect of arithmetical skills. The difficulty lies in the reception, comprehension, or production of quantitative and spatial information. Students with dyscalculia may have difficulty in understanding simple number concepts, lack an intuitive grasp of numbers and have problems learning number facts and procedures. These can relate to basic concepts such as telling the time, calculating prices, handling change." (SASC)
WHAT ARE THE MAIN DIFFICULTIES I SEE IN CHILDREN AND ADULTS WITH DYSCALCULIA?
finding it hard to calculate the right money in a shop (perhaps giving a £10 that will 'cover' the cost of the shopping)
finding it hard to check that you have been given the right change
taking longer to learn to tell the time and finding the 24 hour clock confusing
having little concept of time, leading to overestimating or underestimating what you can do in a certain period of time)
taking longer to learn your times-tables and perhaps never really mastering them
However, I also see many people whose maths is affected by other difficulties such as dyslexia, visual perception difficulties, etc. rather than dyscalculia.
It can be helpful to know that having a specific learning difficulty does not mean that you can not achieve your goals. Indeed, many people with SpLDs play to their strengths which can include creativity, lateral thinking, being empathetic, etc. Over the years, I have assessed many artists, photographers, architects, company directors, teachers, nurses, GPs, vets, an A&E consultant and an international human rights lawyer.
