Dyscalculia vs Number Dyslexia: Signs, Tests and Classroom Strategies
Spot the signs of dyscalculia with our 24-point teacher-led checklist. Practical strategies for supporting pupils who struggle with number sense.
What is Dyscalculia?
As a teacher, recognising and supporting students with dyscalculia can transform their mathematical learning experience from frustration to success. This specific learning disorder, often called 'number dyslexia', affects how approximately 1% of your students process numbers and mathematical concepts, making everyday classroom tasks like counting, basic arithmetic, and number recognition genuinely challenging. Many students with dyscalculia go undiagnosed throughout their school years, struggling silently whilst their difficulties are mistaken for lack of effort or ability. The right classroom strategies and understanding can help these students unlock their mathematical potential and build genuine confidence with numbers.
The National Dyscalculia Association estimates that around 1% of people are affected by this condition. The NDSA also says that it may be more common than previously thought because many sufferers don't realise they have dyscalculia until later in their lives. While dyscalculia cannot be 'cured,' there are evidence-based interventions and teaching strategies that can significantly help students but there are ways you can help your child develop strategies to cope with maths difficulties. Many children struggle with understanding mathematical concepts, these abstract ideas can be difficult to grasp.
Key Takeaways
- Early identification is paramount for effective dyscalculia intervention. Dyscalculia is characterised by a persistent difficulty with number sense, impacting basic arithmetic and mathematical reasoning, distinct from general learning difficulties (Butterworth, 2010). Recognising these early signs in learners allows for targeted support, preventing the accumulation of mathematical learning gaps and fostering greater confidence.
- Multi-sensory teaching approaches are highly effective for learners with dyscalculia. Learners with dyscalculia benefit significantly from multi-sensory methods that engage visual, auditory, and kinesthetic pathways, helping to build a robust understanding of mathematical concepts (Dowker, 2005). This approach aids in solidifying number sense and operational fluency, which are often areas of struggle for these learners.
- Dyscalculia stems from specific cognitive deficits, often distinct from reading difficulties. While sometimes co-occurring with dyslexia, dyscalculia primarily involves deficits in core number processing, working memory, and retrieval of arithmetic facts, rather than phonological processing issues (Geary, 2011). Understanding these distinct cognitive profiles is essential for accurate diagnosis and tailoring appropriate classroom strategies for learners.
- Comprehensive assessment and appropriate classroom accommodations are vital for supporting learners with dyscalculia. Accurate assessment, including diagnostic tests, helps to differentiate dyscalculia from general maths anxiety or poor instruction, providing a clear basis for support (Shalev, 2001). Implementing accommodations such as extended time, use of manipulatives, and structured practise can significantly improve a learner's access to the curriculum and reduce anxiety.
Dyslexia for numbers or dyscalculia is different as it is a learning disability that can often go under the radar for years if not a lifetime. A learning difficulty left undiagnosed at best will harm a child's education. At its worse, it runs the risk of putting off children from learning for life, significantly impacting student wellbeingand social and emotional development. Arithmetic skills are a fundamental part of life and children who continue to struggle with mental maths might need a different pedagogical approach to their learning. In this brief article we look at how children with dyslexia can be supported to develop the essential mathematical skills needed to engage with the curriculum. We will also explore a new visual strategythat supports children with poor memory.
Mind map showing dyscalculia at centre with five branches covering definition, symptoms, causes, impact, and strategies" loading="lazy">Dyscalculia is a learning disorder that primarily affects mathematics and can be found in several other learning disorders such as dyslexia assessment and ADHD. The disorder affects perception of numbers, difficulties understanding word related to numbers, difficulty with basic calculations and more. Understanding this disorder is key for teachers and mental health professionals who are helping individuals with these conditions.
One of the more common forms of dyscalculia is developmental dyscalculia, which affects an individual's brain development. It affects the understanding and use of numerical concepts, difficulties in multiplication and division processes, difficulty with basic calculations such as addition and subtraction, as well as difficulty with understanding math-related words. This disorder can affect individuals across all age groups; however, it most commonly presents itself during early childhood.
The exact cause of dyscalculia has yet to be determined, however it is thought to have a genetic component in some cases. For those with this disorder to get a proper diagnosisfrom a medical or educational professional to find the individualized strategies they need to help them manage their difficulty.
Some researchers believe that dyscalculia has both genetic and environmental components. This means that while some individuals inherit genes that predispose them towards developing dyscalculia, other factors such as early experiences contribute to whether someone develops dyscalculia.
What are the signs of Dyscalculia?
Research shows dyscalculia affects learners' number skills. They find number words hard, struggle with calculations, and miss patterns (Butterworth, 2005). Learners may struggle to link numbers to objects (Geary, 1993). Poor number sense and trouble estimating are also common (Dehaene, 1997). They find maths symbols confusing (Dowker, 2004).
Dyscalculia affects the way a person thinks and processes information, which means that some aspects of mathematics might seem difficult. This could include:
- Difficulty understanding what number words mean.
- Misunderstanding how addition works.
- Not being able to recognise patterns such as multiplication tables.
- Having difficulty remembering things like times tables.
- Understanding that one-to-one correspondence is not always possible between numerical symbols and their corresponding objects or actions. For example, "two" may be used as an adjective for describing something good but also as a noun meaning "twice".
- Difficulty understanding how many items there are in a group of things.
- Difficulty counting by ones, tens, hundreds, etc.
- Aphasia, nonverbal, involving inability to compute or understand arithmetic facts.
- Arithmetic disability, including dyscalculia, is not considered an organic mental disorder by most authorities.
- It may be associated with other disorders such as attention deficit hyperactivity disorder, learning disabilities, reading difficulties, language impairment, autism spectrum disorders, and specific phobias.
- The use of manipulatives, such as cubes, rods, rulers etc., in class activities;
- Using interactive whiteboards to show examples or explain concepts;
- Use of calculators/computers with software that can be used by teachers to create lessons on-line;
- A range of different types of mathematics games;
- Different ways of presenting information through graphs, charts, tables etc.;
Children who have been diagnosed with dyscalculia may be able to count up to 10 or 12 items but cannot do so accurately. They also tend to miss out on subtraction problems that involve numbers greater than 4. For example, if you ask them what comes after 7 they might say 8 instead of 9 because it sounds like an easier problem for them. This type of error is called "subtractive confusion".
The term dyscalculia was coined by Ladislav Kosc in 1974, who described it as a disorder that affects arithmetic ability and defined it as an inability to understand or use numerical concepts. The term has been widely adopted since then and is now commonly used to describe any mathematical disability affecting numerical processing and calculation skills.
Number dyslexia is a term sometimes used to describe trouble with math. If you have problems reading numbers, then your problem might be called "number dyslexia." It doesn't mean you can't do math at all. In fact, many people with number dyslexia are very good at math. They just find some things more difficult than others. Number dyslexia usually starts early in life. Children often learn how to count before they start school. And when children get older, their brains develop new skills for dealing with numbers.
What causes Dyscalculia? There's no single cause of dyscalculia; rather, it seems to result from several different factors working together. These factors include brain damage, learning disabilities, attention deficit hyperactivity disorder and other conditions. Some researchers believe that genetics plays a role too. There isn't enough research yet to know whether these factors work independently or interactively. These factors include brain damage, learning disabilities, attention deficit hyperactivity disorder and other conditions.
However, we do know that dyscalculia tends to run in families, suggesting there may be a hereditary component. Research indicates that children with a family history of dyscalculia may be at higher risk of developing the condition themselves. So far, scientists haven't found much evidence that environmental influences play a major part in causing dyscalculia. How common is it? Estimates vary greatly depending on which study you look at.
One estimate suggests there may be about 1% of the population affected. Another says up to 5%. A third puts the figure even higher: 10-20% of the general population. Why don't doctors diagnose it? Doctors aren't trained to recognise dyscalculia. Most medical students only take two hours' training in basic maths during their studies. Many doctors think that mathematics is simply another language skill, something everyone learns naturally through experience. Others feel uncomfortable diagnosing mental health issues.
What treatments exist? People who struggle with arithmetic tend to rely heavily on visual cues such as pictures, diagrams and models. This helps them remember what they've learned. But not everyone responds well to visuals. For example, someone with dyscalculia may need to see written instructions instead. Other strategies include using symbols to represent quantities, writing out calculations by hand, or asking friends or family members to help with simple tasks like adding money into a bank account.
Dyscalculia in Adults: Lifelong Impact
Dyscalculia presents challenges for adults with maths. They struggle with finance and time (Butterworth, 2010). Learners find budgeting and measuring difficult (Emerson & Babtie, 2006). Workplace calculations become hard, impacting independence (Parsons & Bynner, 2005).
Adults with dyscalculia often struggle with everyday tasks like managing finances, reading clocks, or calculating tips at restaurants. Many adults don't realise they have this condition until later in life, as they've developed coping mechanisms to hide their difficulties with numbers. Without proper support, these challenges can impact career choices and daily independence.
Dyscalculia, similar to dyslexia, is a specific learning difficulty. Learning difficulties often co-occur, (Butterworth, 2010). Learners with dyscalculia may have dyslexia, dyspraxia or ADHD/ADD. Dysgraphia is common in adults with dyscalculia. Other issues include dysorthography and phonological processing problems, (Rubinsten & Henik, 2009; von Aster & Shalev, 2007). Reading, spelling, perception, attention, anxiety, depression, OCD, autism and neuropsychiatric disorders may also be present, (Fine, et al., 2018).
Does Dyslexia Affect Math Skills?
Dyscalculia, or 'number dyslexia,' impacts maths. It affects number processing and calculations (Butterworth, 2010). This learning difficulty affects around 1% of learners. Researchers like Geary (2004) study dyscalculia.

Is Number-Only Dyslexia Possible?
Dyscalculia, or 'number dyslexia', means dyslexia affects numbers (Butterworth, 2010). Learners struggle with maths concepts and basic calculations (Geary, 2004). Numerical processing is affected, while other areas remain unaffected (Shalev, 2000).
This directly addresses the common search query "can dyslexia be with numbers" which receives 26 monthly impressions.
Common Questions About Dyscalculia
Here are answers to the most frequently asked questions about this topic, based on what teachers and educators commonly search for.
Dyscalculia vs Dyslexia: Key Differences
Research (Butterworth, 2005) shows dyscalculia hinders number processing. It impacts learners' calculations and mathematical thinking. Dyslexia (Snowling, 2000) mainly affects reading and writing skills. It causes issues with word decoding and spelling (Elliott & Grigorenko, 2014).
Students can have both conditions simultaneously, requiring tailored support strategies for each area of difficulty.
How do you identify dyscalculia in the classroom?
Researchers identify dyscalculia by watching for ongoing issues with numbers. Learners struggle with mental maths and spot patterns slowly (Butterworth, 2010). Mathematical symbols often confuse them. Learners perform below expectations, despite good teaching and average intelligence (Geary, 2004).
Educational psychologists' assessments give clear diagnoses. They also offer specific ideas for helping learners in the classroom. (Frederickson & Cline, 2002; Farrell, 2009; Griffiths, 2020). This helps teachers provide effective support.
What are the main signs of dyscalculia in students?
Main signs of dyscalculia include difficulty counting backwards, problems understanding place value, struggles with telling time, confusion over mathematical operations and poor number sense. Students often use finger counting beyond age-appropriate expectations and have trouble with word problems.
These difficulties persist despite regular teaching and often cause significant anxiety around mathematics lessons.
How can teachers help students with dyscalculia?
Teachers help students with dyscalculia by using visual aids, concrete manipulatives, breaking tasks into smaller steps and providing extra time for mathematical work. Multi-sensory teaching approaches, number lines and calculators support learning whilst building confidence through achievable goals.
This approach allows learners to confidently tackle more complex problems (Johnston-Wilder & Lee, 2010). Maths anxiety can hinder progress, but positive reinforcement aids resilience (Dweck, 2006). Boaler (2009) suggests number fact practise builds a strong foundation for further maths study.
Classroom Accommodations for Dyscalculia
According to experts, visual methods and maths tools can help. Give learners more time (Butterworth, 2010). Calculators help with complex sums. Breaking down problems helps learners grasp concepts (Dowker, 2004). Use objects to show ideas (Hughes, 2001).
While there's no cure for dyscalculia, effective accommodations include using visual aids, manipulatives, and allowing extra time for math tasks. Teachers can provide calculators for basic operations, break down complex problems into smaller steps, and use concrete examples to explain abstract concepts. Regular practise with multi-sensory approaches helps students develop compensatory strategies.
Providing extra time for testing or writing an assignment may help students who struggle with mathematics because it allows them to complete their work without rushing. It also gives teachers another opportunity to observe how well each student performs under pressure. Providing additional materials such as calculators or computers.
Some people find using technology helpful when doing arithmetic problems. Computers allow users to type numbers into a calculator-like device instead of having to write out calculations by hand.
Teaching Methods for Dyscalculia Students
Multi-sensory approaches help learners with dyscalculia grasp maths, using sight, hearing, and touch. Manipulatives, visual aids, and clear steps aid learning. Frequent practice with feedback builds number sense (Butterworth, 2010; Ansari, 2008).
Children with dyscalculia learn math best through visual and hands-on methods rather than traditional abstract teaching. Using physical objects, colour-coding number patterns, and connecting math to real-world situations helps make concepts more concrete. Consistent practise with patient support and celebrating small victories builds confidence and mathematical understanding.
arithmetical dyslexia, arithmetical disability, Gerstmann syndrome. Recent research by Temple (1991), Butterworth (1999), and Dehaene (1997) explores this area. They suggest aphasia affects a learner's number skills. Dyscalculia isn't usually seen as a mental disorder. It can link to ADHD and learning issues. Temple (1991), Butterworth (1999) and Dehaene (1997) show the term 'number dyslexia' now replaces older labels.
• Arithmomania, A condition characterised by excessive counting, especially of coins, bills, etc., which leads to hoarding behaviour. This was once called arithmania.
• Arithmatica, An abnormal interest in mathematical subjects.
• Arthimania, Excessive love of numbers.
Other Terminology associated with Number Dyslexia
Multi-Sensory Teaching Methods for Dyscalculia
The best classroom tools for teaching maths to dyscalculic students include number lines, counting blocks, visual fraction models, and digital mathematics programmes. Physical manipulatives such as base-ten blocks, calculators, and interactive whiteboards help students visualise mathematical concepts and reduce cognitive load during problem-solving.
There are some very good resources available to develop math concepts, especially for those with number dyslexia. These include:
Learners with dyscalculia could also benefit from using our specially designed learning blocks. The blocks have been used to help children grasp basic maths concepts. Activities include building number lines, exploring place value and creating basic math operations. Educational psychologists and SENDCos are always looking for tools to make number concepts less abstract. Using colour and shape to develop spatial reasoning has become common place in classrooms around the world. Building spatial reasoning skills can help reduce levels of Mathematics anxiety.
From a child's perspective, we can embed mathematical reasoning into a fun and engaging classroom activity. You can see examples of the blocks being used in Maths on our dedicated webpage.
Number Sense and Learning Difficulties
Butterworth (2019) suggests number sense is understanding quantities and maths. Dyscalculia hinders number sense development (Butterworth, 2019). Learners struggle with estimations, number size, and patterns (Butterworth, 2019). Poor number sense impacts later mathematical learning (Dehaene, 2011; Piazza, 2010).
Number sense forms the foundation of mathematical understanding, yet for children with dyscalculia, this intuitive grasp of numerical relationships remains elusive. Unlike typical learners who naturally develop an understanding of quantity, magnitude, and numerical patterns, learners with dyscalculia struggle to form these fundamental connections. Recent research by Fauzi et al. (2024) demonstrates that working memory and number concept development are intrinsically linked, suggesting that difficulties in one area compound challenges in the other. This relationship explains why traditional rote learning methods often fail these students, as their working memory cannot adequately support the processing and retention of numerical information witho ut proper conceptual understanding.
The absence of strong number sense creates a cascade of learning difficulties that extend far beyond basic arithmetic. Children who cannot intuitively understand that 7 is closer to 10 than to 2, or that 15 can be decomposed into 10 and 5, face significant barriers when encountering more complex mathematical concepts. These learners often rely on inefficient counting strategies well into secondary school, using their fingers for calculations that peers complete mentally. This dependency on concrete counting methods, whilst providing temporary support, ultimately hinders the development of mathematical fluency and confidence.
Multi-Sensory Approaches for Number Sense
Intervention should use many senses, not just numbers. Visuals like number lines help learners picture maths (Uttal et al., 2009). Movement activities link numbers to real things (Piaget, 1954). This helps learners with working memory issues (Alloway, 2009).
Teachers can implement targeted number sense activities throughout the school day, not solely during maths lessons. Quick estimation games using classroom materials, such as guessing the number of pencils in a jar or comparing the heights of book stacks, help develop magnitude understanding. Creating number talks where learners explain their thinking about simple problems like "Which is closer to 50: 48 or 42?" builds metacognitive awareness whilst revealing misconceptions. For learners with severe dyscalculia, breaking down number sense into micro-skills, such as recognising dot patterns without counting or understanding "one more" and "one less" relationships, provides achievable stepping stones towards broader mathematical competence. Regular assessment of these foundational skills ensures that gaps in number sense are identified and addressed before they compound into more significant learning barriers.
Teacher-Led Dyslexia Checklist
Before requesting a formal assessment, teachers can use this observation checklist to gather structured evidence of a learner's difficulties. Tick each indicator you have observed consistently over time, not just on a single occasion. The more items ticked, the stronger the case for referral to a specialist assessor or educational psychologist.

Testing and Assessment Accommodations
Sokolová et al. (2022) say dyscalculia is often unseen, leading to misinterpretations. Adapt the classroom environment to support learners better. Consider physical space, sensory needs, and structural changes. These adjustments improve numerical processing, researchers argue.
Physical classroom modifications should prioritise reducing cognitive load and supporting visual processing. Position learners with dyscalculia away from high-traffic areas to minimise distractions, preferably near the front where they can clearly see board work. Use colour-coded materials consistently throughout the room, such as red for tens and blue for ones in place value work. Create dedicated maths manipulative stations with clearly labelled containers, allowing learners to independently access concrete materials like counting bears, number lines, and base-ten blocks. Wall displays should feature simplified number charts with clear spacing between digits, avoiding cluttered arrangements that can overwhelm visual processing.
Creating Supportive Classroom Environments
Mihajlovic and Meier (2023) say adapt the environment for learning. Use tactile number lines on desks so learners trace numbers. Create movement zones for learners to walk number lines. Try rhythmic clapping for times tables or use headphones.
Classroom structure is key. Use visual timetables for maths, helping learners prepare (Geary, 2010). Provide private workspaces to limit distractions during tasks (Butterworth & Yeo, 2004). Establish a buddy system for discreet support (Dowker, 2004). Normalise using accommodations in your classroom. Display problem solving strategies, valuing visual methods alongside algorithms (Sharma, 2021).
Co-occurring Learning Difficulties with Dyscalculia
Adults often live with unrecognised maths difficulties, despite focus on learners. They use calculators and avoid tasks with numbers (Butterworth, 2010). These strategies can limit jobs and independence (Parsons & Bynner, 2005). Educators should understand adult dyscalculia; parents may struggle with homework. This creates maths anxiety in families (Gifford, 2005).
Adults with dyscalculia face challenges at work, like budget management. Ahn's (2024) AI tools show promise for adult learners' numerical skills. These interventions adapt to learners, offering visual aids. Educators should introduce assistive tech early, helping learners develop lifelong strategies.
Supporting Adult Learners with Dyscalculia
Chai et al. (2019) found multimedia boosts learning for adults, especially those with dyscalculia. Brain-based methods help learners build number skills. Combining sight, sound, and movement works well. This approach adapts childhood methods to adult lives.
For teachers working with parents or in adult education contexts, recognising dyscalculia symptoms in adults becomes essential. Adults may exhibit anxiety around number-based tasks, consistently arrive late due to time-telling difficulties, or struggle with everyday calculations like splitting bills or measuring ingredients. By acknowledging these challenges without judgement and providing practical tools, such as visual fraction walls for cooking measurements or colour-coded spreadsheets for budgeting, educators can helps adults to develop numerical confidence. This support extends beyond the individual, as parents who understand their owndyscalculia can better advocate for their children's needs and work collaboratively with schools to implement
Essential Dyscalculia Teaching Resources
Visual number charts aid learners with dyscalculia (Geary, 2004). Manipulatives and graphing software help too (Mazzocco, 2007). Structured worksheets support maths learning (Butterworth, 2010). These tools give concrete examples (Kaufmann, 2011). They support memory and use multiple senses for understanding (De Smedt, 2016).
Effective tools for teaching children with dyscalculia include number lines, base-ten blocks, digital math apps with visual representations, and graph paper for organising calculations. Memory aids like multiplication charts, finger counting strategies, and math games that incorporate movement also support learning. Technology tools that provide immediate feedback and allow repeated practise at the student's pace are particularly beneficial.
How does Numicon work?
Numicon is a great tool for visualising math concepts and could be very useful for individuals with dyscalculia. It can be used to help teach and reinforce basic mathematical skills, such as counting, addition, subtraction, multiplication and other basic number concepts. The app also includes an interactive calculator that allows you to practise basic math skills. You don't need any previous experience or knowledge of mathematics to use this app, it's designed to remove barriers to Maths.
What is Singapore Maths?
Singapore maths has been adopted in many schools around the UK. This overarching approach to number involves using concrete and pictorial representation of number. This method helps students understand numbers better by breaking them down into smaller parts and then combining those pieces together again. The country's success in mathematics education was recognised when it won the prestigious International Mathematics and Science Study award for excellence in science teaching last year. The IMSS awards are given annually to countries that have made significant improvements in their performance in math and sciences over time. In this article we look at how Singapore uses evidence-based approaches to
What are Dienes Blocks used for?
Dienes blocks are another good approach to Maths. Like the broad umbrella term of Singapore Maths, students manipulate blocks in different ways to express numbers and patterns. For example, they may stack two blocks on top of each other to represent 10; place one block under another to show 5+5=10; or add up all the blocks to find out what total amount there is. These manipulatives allow students to explore abstract ideas through physical manipulation. They provide opportunities for students to develop conceptual understanding and problem solving strategies.
Teacher FAQs About Dyscalculia Support
How Common is Dyscalculia in Classrooms?
Dyscalculia is a learning disorder that affects mathematical ability, often called 'number dyslexia'. It affects approximately 1% of learners according to the National Dyscalculia Association, though it may be more common as many cases go undiagnosed for years.
Key Dyscalculia Warning Signs for Teachers
Teachers should watch for difficulty understanding number words, trouble with basic calculations like addition and subtraction, inability to recognise patterns such as multiplication tables, and problems with one-to-one correspondence between numbers and objects. Children may also struggle with counting accurately beyond 10-12 items and experience 'subtractive confusion' where they give incorrect sequences.
Adapting Teaching Methods for Dyscalculia Students
Using visual methods helps learners with poor memory (Baddeley, 1992). Teachers can use symbols for quantities (Skemp, 1971). Give written, not verbal, instructions to learners (Sweller, 1988). Pictures, diagrams, and models aid mathematical concept recall (Bruner, 1966).
Why does dyscalculia often go undiagnosed in schools?
Dyscalculia frequently goes undiagnosed because many professionals, including doctors, aren't trained to recognise it, with medical students receiving only two hours of basic maths training. Many assume mathematics difficulties are simply a natural learning challenge rather than a genuine learning disorder.
Impact of Undiagnosed Dyscalculia on Education
Undiagnosed dyscalculia can significantly harm a child's education and, at worst, put them off learning for life. It can severely impact student wellbeingand social and emotional development, as arithmetic skills are fundamental to daily life and academic success.
Ensuring Proper Dyscalculia Support in Schools
Dyscalculia requires diagnosis from medical or educational experts. Early identification is vital; it isn't laziness. Understanding this helps teachers and mental health professionals create individual learning plans (Butterworth, 2005; Chinn, 2015).
Dyscalculia Causes and Treatment Options
There's no single cause of dyscalculia, though it appears to result from several factors including brain development issues, genetics, and possibly environmental components, with the condition tending to run in families. Whilst there's no cure or treatment, children can develop coping strategies through adapted teaching methods and visual learning approaches.
