Overview
What it is
Dyscalculia is a learning difference that affects math — understanding numbers, quantities, and mathematical reasoning. Sometimes called “math dyslexia,” it's not about intelligence or effort. With explicit, well-designed instruction and the right tools, students with dyscalculia can build strong math skills.
Signs
Signs & characteristics
- Weak number senseTrouble grasping quantities and how numbers relate
- Difficulty with math factsStruggling to memorize and recall basic facts
- Trouble with sequences & place valueConfusing steps or digit positions
- Difficulty with time, money, or estimationEveryday number tasks are hard
- Math anxietyFrustration and avoidance around math
Evaluation
Evaluation & testing
Dyscalculia is identified through a comprehensive evaluation that assesses math skills and number sense alongside cognitive and processing measures (comparing math achievement to overall ability). A school or private evaluation can determine eligibility for support.
