Dyscalculia is a math-related learning disability that makes math tasks difficult for students. Children with dyscalculia may struggle with number sense, memorizing math facts, recognizing patterns, and understanding information from charts or graphs. Dyscalculia affects a student's working memory and ability to solve multi-step problems. Genetic disorders and conditions affecting brain development can increase the risk of dyscalculia. Treatment focuses on multisensory instruction that builds math skills systematically using concrete examples and visual aids.
