What is dyscalculia?
Dyscalculia is a specific learning difficulty that affects a person’s arithmetical ability. In terms of research it remains the baby of the specific learning difficulties family. There’s a wealth of knowledge and understanding about dyslexia, dyspraxia and autism, but much less is known or understood about dyscalculia.
Coined in the mid-20th century, the word dyscalculia has both Greek and Latin origins: the Greek prefix ‘dys’ means ‘badly’, while ‘calculia’, from the Latin ‘calculare’, means to count. So, literally dyscalculia means to count badly. The reality is much more complex than this.
Common Difficulties
People with dyscalculia may struggle with any or all of the following areas:
Estimation – being able to tell if an answer is reasonable or not.
Short- and long-term memory – difficulty remembering procedures in maths
Time – many children have difficulty in learning to tell the time, but this can persist in learners with dyscalculia. They can also have difficulty with appreciating the passage of time. So they may not be able to tell whether 1 minute or one hour has passed.
Assessing numerical quantity – eg when given two numbers a dyscalculic learner will have difficulty in identifying which is the larger.
Money – this can be a severe difficulty and often stems from a lack of understanding of place value. For example, not being able to appreciate that a £20 note will be sufficient to cover a £15.75 taxi fare.
Performing calculations – both in choosing the correct numerical operation and applying it correctly
Sequencing and recognising patterns
Counting backwards and counting in steps
Direction/ orientation – difficulty in understanding spatial orientation, confusion over left and right, leading to difficulties in map-reading and following directions
Definitions of dyscalculia
As with dyslexia, there is no single commonly accepted definition of dyscalculia. The Department for Education and Science (DfES) describes it as:
‘ … a condition that affects the ability to acquire arithmetical skills. Dyscalculic learners may have a 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’
A more quantifiable definition, perhaps, is given by the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM IV) which sees dyscalculia as a mathematics disorder:
‘As measured by a standardized test that is given individually, the patient's mathematical ability is substantially less than you would expect considering age, intelligence and education. This deficiency materially impedes academic achievement or daily living.’
As with dyslexia, there is no single commonly accepted definition of dyscalculia. The population is far too heterogeneous.
The American Psychiatric Association (2013) defines Developmental Dyscalculia (DD) as:
A specific learning disorder that is characterised by impairments in learning basic arithmetic facts, processing numerical magnitude and performing accurate and fluent calculations.
These difficulties must be quantifiably below what is expected for an individual’s chronological age, and must not be caused by poor educational or daily activities or by intellectual impairments.
DfES (2001). The National Numeracy Strategy. Guidance to Support Learners with Dyslexia and Dyscalculia. London. DfES
APA (1994), Diagnostic and Statistical Manual of Mental Disorders . Washington, DC, ed. 4. American Psychiatric Association
The impact of dyscalculia
The impact of dyscalculia is far reaching and can have a profound impact on daily life, especially work.
For example, some dyscalculic adults never learn to drive, because of the numerical demands of driving and map reading (although SAT NAVs can help a great deal here).
Dyscalculia can also lead to social isolation, due to an inability to be at the right place at the right time, or to understand the rules and scoring systems of games and sports.
It can have a severe impact on job prospects and promotional opportunities for those in work.
Personal finances and budgeting will also be an issue for people with dyscalculia. Research shows that adults with low numeracy earn on average £2,100 less per annum than adults with average or above numeracy. In the UK as a whole, it is estimated that low numeracy levels cost the UK £20 billion per year, largely due to poor productivity. (National Numeracy, 2014)
To have dyscalculia can be a very frustrating experience, but it does not mean that you will never achieve in life. It is, after all, a specific learning difficulty. Paul Moorcraft’s book ‘It just doesn’t add up’ is testament to what can be achieved despite having severe dyscalculia. Surprisingly, a number of mathematics professors could be described as dyscalculic, reminding us that this is a specific difficulty with arithmetic and not with every branch of mathematics.

Co-occurring difficulties
Specific Learning Difficulties (SpLD) is an umbrella term used to cover a range of frequently co-occurring difficulties. SpLD affect the way information is learned and processed. They are neurological (rather than psychological), usually hereditary and occur independently of intelligence.
A range of studies have indicated high levels of overlap between dyscalculia and other SpLD. This has led to the assertion by Kaplan (2001) that ‘in developmental disorders, co-morbidity is the rule, not the exception’.

Current research into dyscalculia
Dyscalculia can affect different aspects of maths ability- leading to a variety of math profiles. Karagiannakis and Cooreman (2014) have identified four areas or subtypes. Dyscalculic learners may have difficulty in all or maybe just one or two to these areas:
- Core Number
- Reasoning
- Memory
- Visual Spatial
1. Core Number
This particular sub type of dyscalculia will lead to difficulties with:
- Basic number sense, which is the ability to use and understand number and our number system
- Estimating, for example, being able to arrive at a rough idea of what the answer may be
- Assessing difference in numerical quantity, for example, understanding that 230 is ten times as much as 23 or that 9 is larger than 7
- Understanding and using mathematical symbols
- Understanding place value, for example being able to write 102 in response to hearing one hundred and two rather than writing 1002
- Placing numbers on a number line, for example , understanding that 5 would be placed in the middle of a number line from 0-10
2. Reasoning:
This particular sub type of dyscalculia will lead to difficulties with:
- Understanding mathematical concepts and relationships. For example, understanding that multiplication is repeated addition or that addition and subtraction are inverse operations
- Generalising and transferring information. For example, using the fact that 5 + 4 = 9 to work out that 50 + 40 = 90 or that 5 + 5 = 10
- Understanding multiple steps in complex procedures/algorithms
- Problem solving and decision making. For example, selecting the best method for solving a problem or deciding which operation to use when solving a word problem
3. Memory
This particular sub type of dyscalculia will lead to difficulties with:
- Remembering and retrieving numerical facts. For example, recall of number bonds to ten or times tables
- Understanding and recalling mathematical terminology. For example, terms like numerator and denominator
- Understanding word problems . To make sense of a word problem often requires you to hold information in your short term memory
- Performing mental calculations accurately. Mental arithmetic places great demands on the working memory
- Remembering and carrying out procedures as well as rules and formulae
- Keeping track of the steps in problem solving
4. Visual Spatial
This particular sub type of dyscalculia will lead to difficulties with:
- Recognising and understanding symbols. For example confusing x with +
- Interpreting visual representations of mathematical objects. For example being able to recognise the net of a square
- Placing numbers on a number line. For example, being able to place 75 in roughly the right place on a blank number line from 0-100
- Visualising geometric figures, such as 3 D shapes
- Interpreting graphs and tables. For example , having difficulty reading information from tables or understanding distance /time graphs

Identification
Please be aware that the indicators listed in this column are only intended to be used as a checklist to provide a basic indication of whether or not an individual may be at risk of dyslexia. If you identify a cluster of difficulties and strengths, your next step should be to consult the school Special Needs Co-ordinator (SENCo) so that appropriate and immediate support can be put in place (see Column 5: Signposting for further intervention / assessment)
Pre-school level indicators
Preschoolers with dyscalculia may have trouble with maths skills like counting, sorting and organizing. For example:
Connecting symbols with numerical quantities- for example matching the number 3 to a plate with 3 biscuits on it
Sorting – grouping things by shape, size or colour
Time - difficulty appreciating the passage of time
Primary level indicators
1.Delay in counting. Five to seven year-old dyscalculic children show less understanding of basic counting principles than their peers (eg that it doesn't matter which order objects are counted in).
2. Delay in using counting strategies for addition. Dyscalculic children tend to keep using inefficient strategies for calculating addition facts much longer than their peers.
3. Difficulties in memorizing arithmetic facts. Dyscalculic children have great difficulty in memorizing simple addition, subtraction and multiplication facts (eg 5 + 4 = 9), and this difficulty persists up to at least the age of thirteen.
These symptoms may be caused by two more fundamental difficulties, although more research is needed to be sure:
1. Lack of 'number sense'. Dyscalculic children may have a fundamental difficulty in understanding quantity. They are slower at even very simple quantity tasks such as comparing two numbers (which is bigger, 7 or 9?), and saying how many there are for groups of 1-3 objects. The brain areas which appear to be affected in dyscalculia are areas which are specialised to represent quantity.
2. Less automatic processing of written numbers. In most of us, reading the symbol '7' immediately causes our sense of quantity to be accessed. In dyscalculic individuals this access appears to be slower and more effortful. Thus dyscalculic children may have difficulty in linking written or spoken numbers to the idea of quantity.

Secondary level indicators
If a pupil is presenting a number of these difficulties, it is a clue that something is wrong and they are experiencing difficulties which will get in the way of them learning arithmetical skills.
Language and Memory
- Doesn’t seem to comprehend the precise meaning of the terms used in mathematics.
- Has difficulty reading mathematical terms.
- Doesn’t remember what the abbreviations for terms mean.
- Has difficulty comprehending questions or holding the ideas long enough to make sense of the request.
Numbers
- Has difficulty linking words and numbers.
- Doesn’t understand the concept of number ie 'threeness' and therefore may answer randomly with any number to a question.
- Has difficulty with sequences.
- Has difficulty with time eg telling the time, concepts of time passing such as yesterday, today, tomorrow.
- Reverses numbers.
- Has difficulty transferring from the concrete to abstract ideas.
Work
- Work is very messy and the columns do not line up.
- Methods are not stable and mistakes cannot be explained.
- May be ok with the tangible but cannot deal with concepts.
- Lacks confidence and avoids estimating and checking or other systematic ways of validating working methods.
- Has problem with place value.
- Has orientation problems eg left and right or vertical and horizontal.
Confidence
- Does not appear confident even with work which should be quite easy.
- Finds ways to avoid being in class, being exposed to arithmetical work.
- Displays stress or withdraws during mathematical lessons.
- Gets tired very easily when doing mathematical work.
- Worries about performance, time taken or being slow.

Top ten Tips for teaching children with dyscalculia
1. Use concrete manipulative materials
Invest in the right kinds of concrete materials and let your child play around with
them, experimenting and having fun with them. Most useful and versatile of all the
resources that I use with dyscalculic learners is a set of Cuisenaire rods. [Cuisenaire
rods are cuboid rods of wood or plastic, in ten fixed colours, ranging in length from
1 cm to 10 cm to represent the numbers from 1 to 10.] Other helpful materials are
chunky counters, Dienes blocks or other base-10 blocks, dice and dominoes.
2. Play with dice and dominoes to improve recognition of spot patterns
Play any games that incorporate the use of dice. Teach your child to recognise the
number patterns on the dice rather than having to rely on counting the spots one by
one after each new throw of the dice. Play domino games, too. Point out the
similarities between the dice patterns and the domino patterns. Encourage your child
to look for patterns inside patterns. For example, inside the traditional spot pattern
for the number 6 one can see two 3s, or three 2s, or the patterns of 4 and 2.
3. Beware the ‘counting trap’
Take care your child does not fall into the ‘counting trap’. This is a self-perpetuating
situation in which a child solves every fresh calculation by counting up or down in
ones because they know so few numeracy facts for certain. Meanwhile, they cannot
increase their store of known facts because the process of finding the answer to a
computation takes so much time and effort that, a) they can never be sure that the
answer is correct, and b) because by the time a solution is reached, the child no
longer connects the answer to the question. To help a child out of this vicious cycle,
focus on composing and decomposing small quantities into chunks, not into a
succession of single units. Play games and activities that highlight numbers being
built out of component chunks, not ones. Introduce as large a variety of games as
possible, in order to provide enough practice with components.
4. Focus on games and activities, rather than worksheets
It is not difficult to find, or invent, simple activities and games that target particular
misconceptions or points of difficulty. Activities present mathematics as a challenge
or a puzzle that needs to be solved in a practical manner. They allow children to
focus on one aspect at a time and to construct mathematical meaning for themselves
at their own rate of understanding. Games encourage children to revisit important
topics regularly, thereby developing some degree of automaticity, whilst maintaining
a high level of interest and enjoyment.
5. Highlight the repeating decimal structure of the number system
Help your child construct an accurate mental model of the decimal number system.
One way is by exploring number tracks. Another is by using base-ten blocks on place
value mats to build 2- and 3-digit numbers and to support step counting in 1s and
10s. Don’t always start a count at zero and switch back and forth between the step
sizes at random intervals. Try a short run of backward steps from time to time.
Extend the concrete step counting beyond 100, paying special attention to the
difficult boundaries between decades and hundreds.
12/09
6. Take a step-by-step approach
Break down each learning topic into the smallest possible incremental steps. Be
prepared to explore, repeat and rehearse each step many times before the child can
be expected to understand it well enough to use it as a foundation for the next step.
7. Help children to construct visual mental models
Encourage your child to use the concrete materials as a basis for creating pictures in
the mind. Discourage any attempt to use the resources mechanically, just to find an
answer. All work with sketches and diagrams should also be seen as a route to
learning or practising visualisation techniques.
8. Explore the language of maths
Explain mathematical terms carefully. Encourage your child to articulate their
thinking at every stage of any maths task. Broaden your child’s mathematical
vocabulary as much as possible, using a wide variety of common synonyms for basic
arithmetic operations. For example, synonyms for ‘subtract’ might include ‘minus’,
‘take away’, ‘less than’, ‘fewer than’, ‘decrease(d)’, ‘take(n) from’, ‘reduce(d)’,
‘difference’, etc.
9. Don’t rush into abstract and written work
Allow your child to spend plenty of time manipulating concrete materials before
anything is written down. Use mathematical notation to record only what your child
already fully understands. Use diagrams and sketches to support a gradual
transition between concrete and abstract work.
10. Teach for understanding
Memory problems are often associated with specific learning difficulties and can have
a severe impact on maths performance. For instance, a common phenomenon
amongst both dyscalculic and dyslexic learners is an inability to memorise
multiplication tables. Take care, therefore, to minimise the number of facts that your
child is expected to commit to memory. Take care also to restrict the number of
strategies your child is expected to master. Limit them to only those key strategies
with the widest applications. Instead of relying on rote-learning, teach children how
to use logic and reasoning to derive new facts and methods from those that they
already know and understand.

SEND Code of practice and whole school approach
Statutory guidance for schools in England on duties, policies and procedures relating to children and young people with special educational needs (SEN) is contained with the SEND Code of Practice (2014).
With maths teaching it is important for schools to create an environment where learners feel safe to explore their ideas and strategies without fear of feeling ‘stupid’ if they get they answer wrong. Moving away from a procedure and answer focused way of teaching to a more exploratory and problem solving approach can also help to alleviate maths anxiety
Supporting dyscalculic learners with word problems
One of the most effective ways to support dyscalculic learners when tacking word problems is to use the bar modeling method. This is a very common method in countries such as Singapore and China and helps the learner to visualise the maths. The model shows them which operation they need to use to solve the problem and what steps they need to take.

Continuing Professional Development
Teachers who are interested in becoming a specialist dyslcalculia teacher or dyscalculia assessor can find information about training courses and professional accreditation on the BDA, Dyslexia Action, Edge Hill University and Learning Works websites.
The BDA also offer a Level 2 accredited 3 day Dyscalculia Course
Seeking further advice
When a pupil fails to thrive or make progress in spite of receiving a well-founded intervention programme, or when a screening test indicates a high probability of dyscalculia, a full diagnostic assessment should be considered.
Diagnostic assessments should always be conducted by a properly qualified, certified assessor. This will be either an Educational Psychologist or an AMBDA qualified specialist teacher. For advice on finding an assessor in the UK, see the BDA website or the PATOSS Tutor/Assessor Index.
Assessments are provided by the BDA Dyslexia Action and PATOSS

Exam provisions
Children and young people in the UK who are identified as having SEN or SpLD are entitled to access arrangements and reasonable adjustments during exams. These adjustments range from additional time in exams to the provision of a scribe/reader or computer based assistance.
Details of these adjustments are published each year by the Joint Council for Qualifications ( JCQ and are freely available online

Strength of Evidence
Although there is not as much research into dyscalculia as there is for dyslexia, there is still a substantial body of research in this area and some strategies will work for some children and some for others. Teachers are advised to consider the advice here in the light of the context in which they are teaching and then to make their own professional judgements about how to work with the individual students they have – always seeking advice from specialists if possible.
Transferability
Dyscalculia is a specific learning difficulty that occurs worldwide and is not more prevalent in one country than another. The research and strategies referred to will be applicable whatever your country of origin. However, the references to assessment and further professional development are UK based.
Editor’s comments
Around 6% of the population are dyscalculic. This means that in every class of 30 pupils, there are likely to be 2 children who will experience difficulties associated with dyscalculia.
The advice in this guide sets a minimum standard of knowledge required to begin to identify and support these children effectively. Dyscalculia trained specialist teachers have an important role in helping schools to set up whole school dyscalculia friendly practices and training, including effective classroom teaching, environment and policies, and effective screening and intervention. Training should include all teachers knowing when to refer the child for further specialist assessment and intervention where appropriate.
