Dyslexia is often associated with difficulty reading, but dyslexia in math is a common challenge for many students. Math is a complex subject made up of symbols, word problems, and concepts of sequence and order. Because it calls on conceptual, logical, and spatial reasoning, parents often wonder: does dyslexia affect math performance even when a child is bright? The answer lies in how the brain processes symbols and sequences.
When people think of this condition, they usually picture letters flipping on a page. However, dealing with dyslexia with numbers is an equally common hurdle. Because digits are abstract visual symbols that must be decoded, sequenced, and recalled just like letters, the exact same neurological pathways responsible for reading difficulties can interfere with numerical fluency.
Much like reading, tasks in math are structured in sets of subskills. For a student with dyslexia for numbers, the cognitive load of reordering digits or recording problems incorrectly can lead to frustration.
This specific struggle often shows up during foundational arithmetic. A student dealing with dyslexia for numbers might perfectly understand the logic of addition or multiplication but continuously stumble because they copy the digits incorrectly from the whiteboard, reverse the order of 21 and 12, or lose track of their place in a column. The issue is not a lack of mathematical logic; it is a breakdown in symbolic processing.
While reading subskills are often evaluated, dyslexia for math often goes overlooked because we assume the two subjects are unrelated. Identifying these subskill weaknesses is essential for mastering future mathematical concepts.
When students are not equipped with sufficient reading skills, storing complex terms like quotient or denominator in their vocabulary becomes difficult. Math dyslexia often manifests most clearly in word problems. Even if a student has knowledge of the correct calculations, comprehending the sentences that frame the problem is a significant hurdle.
It is important to distinguish between different learning profiles. While dyslexia for math is often rooted in decoding, encoding, and language-based memory issues, dyscalculia specifically affects the brain’s ability to understand quantities and mathematical facts.
To understand exactly how does dyslexia affect math, it helps to look at the specific language demands of the subject. While dyscalculia impairs the innate sense of numerical magnitude, language-based learning differences disrupt math performance through:
Word-to-Symbol Mapping: Difficulty translating written words (like minus, product, or times) into their correct mathematical operational symbols.
Rote Memory Gaps: Intense frustration when trying to memorize sequential math facts, such as times tables, despite understanding the underlying concept of multiplication.
Procedural Confusion: Getting lost during multi-step operations (like long division or algebraic equations) due to working memory overloads.
Both require specialized, multisensory approaches to help the learner visualize the concepts.
Some students with dyslexia are able to excel in higher level math. However, dyslexic students may struggle with math facts that they need to build on in order to perform higher level problems more easily. It is essential to determine where in the process of problem solving that these issues in math occur.
Evaluation of skills is necessary. Math requires so much brain power! Organizing, naming, sequencing, and recognizing and relating quantities are all skills that go into different math problems. Math often requires the use of multi-step tasks as well. Students with dyslexia would benefit from being assessed on these skills in order to move forward in math.
Consider how a different learner’s brain works. For reading, many instructional methods are implemented to break down words and to learn vocabulary and context. For math, students with dyslexia can benefit from approaches that help them to visualize math, to talk out math problems, and to organize information so that they can solve problems.
Many processes are working in the brain for math and reading. As in reading, many cognitive steps and systems are at work when a student is doing math. Integrating multisensory approaches to help students connect with math can be effective and successful.
Because of the relationship between students with dyslexia and math, a calculator is an often used and appropriate classroom accommodation. Learn more about dyslexia treatment at Dyslexia on Demand.
