WHAT IS DYSCALCULIA?
Understanding Dyscalculia and Its Impact on Learning
Dyscalculia is a specific learning disorder that affects an individual’s ability to understand numbers, perform calculations, and grasp mathematical concepts.
While dyslexia is widely recognised, dyscalculia—a “number-based” learning difficulty—remains less understood, even though the two conditions can co-occur.
Many children who are perceived as “struggling with maths” may, in fact, have dyscalculia. Without proper identification and support, these learners can experience ongoing challenges that affect confidence, academic progress, and everyday numeracy skills. This highlights the critical importance of professional learning disability assessments.
At SGDA, we specialise in the assessment and support of dyscalculia. We employ the only HPCSA-endorsed Dyscalculia Test in South Africa and follow a scientifically grounded approach that maps how different areas of the brain contribute to numerical understanding, problem-solving, and mathematical reasoning. Our goal is to provide accurate diagnosis, personalised intervention, and lasting support for learners.

SYMPTOMS OF DYSCALCULIA
Dyscalculia is a learning difficulty that can affect multiple aspects of numerical understanding and mathematical reasoning. Common challenges include:
- Understanding numbers and quantities –
difficulty grasping how numbers relate to one another. - Difficulties understanding maths concepts –
struggling to make sense of mathematical ideas and principles. - Recall of basic facts –
challenges with addition, subtraction, multiplication, and division. - Mental calculation –
difficulty performing calculations in the head. - Sequences and ordering –
trouble understanding number patterns, sequences, or procedural steps. - Time, direction, and measurement –
difficulty reading clocks, estimating time, measuring, or following directions. - Step-by-step problem-solving –
challenges following multi-step mathematical procedures.
It is important to note that low intelligence does not cause dyscalculia. Individuals with dyscalculia are bright and capable—their brains simply process numbers differently. Early identification and support can help learners reach their full potential.

HOW IT WORKS
How the Brain Processes Maths
At SGDA, we assess the three key neurological systems involved in mathematical learning and identify how differences in brain function contribute to dyscalculia:
Fact Retrieval
This system relies on the Angular Gyrus and the Intraparietal Sulcus (IPS), which enable the brain to store and quickly recall basic mathematical facts. When these areas function differently, learners may struggle to retrieve numbers and perform calculations efficiently.
Learning Strategies
The Inferior Prefrontal Cortex and Bilateral IPS support planning, reasoning, and strategy selection for solving mathematical problems. Difficulties in these regions can make it challenging to approach new or multi-step tasks with confidence and flexibility.
Visual–Spatial Processing
The Superior Parietal Lobule and Inferior Parietal Cortex underlie spatial awareness, mental number lines, and understanding quantitative relationships. When this system is affected, learners often find it hard to recognise patterns, organise information, or grasp visual and spatial maths concepts.
By evaluating these three systems, SGDA provides a comprehensive understanding of why learners with dyscalculia face difficulties and what targeted support is needed to help them succeed.
COMMON SYMPTOMS
How Dyscalculia Manifests in Daily Life
When dyscalculia is not identified and supported early, it can impact confidence, independence, and overall well-being. Symptoms may present differently across age groups:
Young Children
- Difficulty counting and recognising numbers
- Challenges with basic addition and subtraction
- Confusion about concepts of “more” or “less”
- Slow problem-solving skills
- Difficulty telling time
School-Age Children
- Ongoing difficulty with counting and number recognition
- Struggles with addition, subtraction, and other mathematical operations
- Challenges understanding quantities and comparisons
- Slow or hesitant problem-solving
- Difficulty reading clocks and managing time
Teenagers and Adults
- Difficulty budgeting and managing finances
- Challenges with measurements and estimations
- Trouble reading maps or understanding spatial information
- Anxiety or stress related to maths
- Persistent difficulties in academic, work, or daily-life tasks involving numbers
CATCH THEM BEFORE THEY FALL
Why Early Learning Disability
Testing Matters
Early assessment is essential for identifying number-related learning difficulties such as dyscalculia. A clear and accurate diagnosis can:

Reduce frustration – help learners understand their challenges and reduce stress.
Support school adjustments – enable tailored classroom strategies and accommodations.
Prevent long-term learning gaps – address difficulties before they compound.
Guide therapy – inform targeted interventions to strengthen numerical skills.
Build confidence – empower learners to approach maths with greater self-assurance.
Timely testing ensures that children receive the support they need to reach their full potential.
DYSCALCULIA TESTING
Comprehensive Assessment for Number-Related Learning Difficulties
At SGDA, our specialised testing programme is conducted by registered professionals trained in dyscalculia assessment. Our goal is to provide a thorough understanding of each learner’s strengths, challenges, and underlying causes, so that targeted support can be implemented.
Parent Questionnaire
and Consent
We begin by gathering essential background information, including early developmental milestones and daily challenges, to inform the assessment process.
Grade-Specific
Test Books (Gr 1–7)
Our carefully designed test books evaluate:
- Number sense – understanding quantities and numerical relationships
- Fact retrieval – recalling basic arithmetic facts efficiently
- Visual–spatial reasoning – recognising patterns, sequences, and spatial relationships
- Problem-solving and calculation strategies – applying logical steps to solve mathematical tasks
- Core mathematical abilities – foundational skills critical for academic success
Standardised Learning
Disability Testing
We assess the neurological systems involved in mathematical understanding, providing insight into how each learner processes numbers, solves problems, and approaches maths tasks.
Diagnosis and
