Dyscalculia

Why it works

Dyscalculia is a specific learning difference affecting the understanding of numbers and mathematics, difficulty with number sense, connecting numbers to quantities, recalling math facts, understanding math concepts and procedures, that is real, neurological, and unrelated to intelligence or effort (the math equivalent of dyslexia). Students with dyscalculia are often mislabeled as lazy or bad at math and lose confidence. Supporting them means recognizing the signs, using approaches that build number sense (concrete and visual representations, explicit instruction, multisensory methods), reducing reliance on memorized facts under pressure, providing appropriate accommodations, and sustaining confidence, so they can access and understand mathematics.

The research: Research on dyscalculia and math learning differences.

The core activity: support real math understanding

Teachers leave with approaches that build number sense and confidence.

Recognize the signs of dyscalculia (number sense, fact recall, concept difficulty).
Build number sense with concrete and visual representations and explicit, multisensory instruction.
Reduce reliance on pressured fact recall and provide accommodations.
Sustain confidence and access to real math.

A real difference, not lazinessDyscalculia makes math genuinely hard, regardless of effort or intelligence. Recognize it, build number sense with concrete and multisensory methods, and sustain confidence and access.

Facilitator notes

Recognize the signs, and build number sense concretely and multisensorily.
Reduce pressured fact recall.
Accommodate and sustain confidence.

Mislabeling dyscalculia as laziness crushes studentsStudents with dyscalculia are often called lazy or bad at math and lose confidence. It is a real difference, recognize it and support real understanding.

Adapt it

Elementary: number sense, concrete, multisensory, confidence.
Secondary: concepts, representations, accommodations, confidence.
All settings: build number sense, reduce pressured recall, sustain confidence.

Common questions

What is dyscalculia?

A specific learning difference affecting number sense and math, difficulty connecting numbers to quantities, recalling facts, and understanding concepts, that is real and neurological, unrelated to intelligence or effort. It is the math equivalent of dyslexia.

Isn't a struggling math student just not trying?

Dyscalculia is a genuine learning difference, not laziness. These students are often mislabeled and lose confidence. Recognize the signs and support them with the right approaches.

How do I support a student with dyscalculia?

Build number sense with concrete and visual representations, explicit and multisensory instruction, reduce pressured fact recall, provide accommodations, and sustain confidence, so they can genuinely understand math.
