Dyscalculia - (revised) The Why’s and how to spot some of the Signs by Dyslexia Dublin CETC © 2013
Dyscalculia can be described as an innate specific learning disability (in the mind) that prohibits various levels of understanding in mathematics. It is very similar to dyslexia and in some cases, children/adults can have both.

The main difference between the two is the difficulty in understanding numbers, ie. 5 back to front and getting sums reversed (54 x 4 can be read as 45 x 4), learning how to manipulate numbers, learning maths facts and a number of other related symptoms. As with dyslexia, Maths disabilities can also occur as the result of some types of brain injury (apraxia), in which case the proper term is acalculia, to distinguish it from dyscalculia which is of innate, genetic or developmental origin.
Although maths learning difficulties can be generic, occurring in children with low levels of academia, dyscalculia also affects people from across the whole IQ range and sufferers often, but not always, also have difficulties with telling the time and measuring (eg. cooking).
Many find counting numbers going forward in a particular patter, however they have problems with reversing numbers especially those that have a sequence involving two's and three's
Estimates of the population with dyscalculia range between 3 and 6%. around 50% of those with dyslexia have dyscalculia and the remainder are generally quite good at mathematics.
Dyscalculia can cause problems with the written maths and indeed for those with dyslexia and dyscalculia, algebra can cause particular problems as the calculations and written word become entwined…however, not so with physical maths (eg. counting with fingers or an abacus) as this is visual. Learning Maths through the visual channel is very important (games , etc.). Also, I find that some, but not all, children are no longer being taught by rote (ie. memorising through repetition)…children with specific learning needs would benefit from this method.
Children suffering from visual stress can also have a problem with writing down sums, as they have a problem in forming columns and rows.
Symptoms of dyscalculia could be if you throw down a number of coins or counters in a random fashion the child/adult would have difficulty in arriving at the correct value/number. They would have a far greater chance of accuracy if they were in rows. Also, with varied objects i.e. one of each…cow, pig, horse, dog for example…they would then use their visual image side to great effect and gain the correct answer and with increased speed too.
Reading a clock is also difficult, especially analogue as opposed to digital…again games can speed this up. Also, going in up in 5’s is good (5, 10, 15 mins) and avoid the ‘to the hour’, just use past the hour, ie. 10,20,30,40 mins past, etc. ‘Quarter past/to’ and ‘half past’ can be introduced later on. Also time keeping can be a problem – it’s beneficial to use minutes when giving instruction, ie. we’re going out in 10 minutes, it’ll be time for bed in 20 minutes, as they will find this easier to understand.
As with Dyslexia, left and right is a problem - with map reading people often turn the map towards the direction they need to head.
Other symptoms are an inability to process multiple requests, difficulty in multi-tasking. Also, problems with reading music and with visualisation in general.
Many adults with dyscalculia have learnt to adapt their world to allow them use their strengths. Being creative for the most part, many become writers and artists
Software intended to intervene and improve children and adult’s academic ability is now widely available.
Multi-sensory educational therapy is a very effective way of increasing academic (ability) age up to a person’s chronological age range.
