Children with disorders in mathematics are included under the definition of Learning Disabilities.  However, in many school systems, special education services are provided almost exclusively on the basis of children's reading disabilities. Even after being identified as having a learning disability in mathematics few are provided substantive assessment and remediation of their arithmetic difficulties.  Approximately 6% of school-age children have math deficits and among students classified as having learning disabilities, arithmetic difficulties are as pervasive as reading problems.
