About Dyscalculia

Illustration of two human heads with brains highlighting different numbered areas. The left head is blue with the numbers 1, 2, and 3 inside the brain. The right head is red with numbers 4, 5, 6, 7, and 9, 10, 11 in different brain regions. Above each head are speech bubbles with handwritten math problems and answers, such as addition and subtraction equations.

Dyscalculia is a specific learning difference that affects a student's ability to understand numbers, develop number sense, learn math facts, and carry out calculations. It is neurobiological in origin, meaning it reflects differences in how the brain processes numerical information.

Students with dyscalculia are not struggling because they are not trying or because they are "not math people." Many work hard and practice repeatedly but continue to have difficulty with skills that require automatic understanding of quantities, relationships between numbers, and mathematical procedures.

Dyscalculia is estimated to affect approximately 5 to 7 percent of people, making it a relatively common learning difference.

With explicit, structured instruction, students with dyscalculia can build stronger number sense, develop effective strategies, and gain confidence and competence in math.

Common Characteristics of Dyscalculia

  • Difficulty understanding that a numeral represents a specific quantity

  • Difficulty developing a sense of number magnitude, for example, understanding which numbers are larger or smaller

  • Trouble learning basic math facts despite repeated practice

  • Trouble remembering and applying multi-step procedures

  • Difficulty telling time, managing money, or using math in everyday situations

  • Slow or inefficient calculation

  • Reduced confidence in math from repeated experiences of difficulty

  • A gap between strong verbal or reading skills and math skills, often one of the first signs families notice

Common Misconceptions About Dyscalculia

  • Dyscalculia is not simply being "bad at math." Many students with dyscalculia have strong reasoning skills and perform well in other academic areas. Their difficulty is specific to aspects of numerical understanding and mathematical learning.

  • Dyscalculia is not a sign of low intelligence or low effort. Students with dyscalculia often work very hard but need instruction that directly addresses the skills that are difficult for them.

  • Dyscalculia is not something students simply grow out of without support. Like dyslexia and dysgraphia, dyscalculia responds to explicit, structured instruction that builds foundational math skills and understanding.

How We Support Students with Dyscalculia

Math is built from many interconnected skills, including number sense, understanding quantities and relationships, remembering math facts, understanding place value, and applying procedures accurately. We identify which skills are creating difficulty for each student and build instruction around those needs rather than following a one-size-fits-all curriculum.

Many students we work with have spent years practicing math facts that have not become automatic or repeating procedures they do not fully understand. This often means the underlying concepts need to be strengthened before more advanced skills can develop.

We build those foundations through concrete materials, visual models, and explicit teaching sequences. Our instruction draws on research-aligned approaches including the Concrete-Representational-Abstract (CRA) framework, Montessori math, and Stern Math. We focus on building conceptual understanding first, then developing the fluency and automaticity students need to apply math skills confidently.

Instruction covers number sense, place value, the four operations, fractions, decimals, and pre-algebra. We support students from early elementary through high school and adulthood, with instruction tailored to each student's current skills and goals.
