Siblings and parents of 39 children with dyscalculia were assessed for arithmetic, reading, and attention disorders. Findings indicated a familial prevalence of dyscalculia almost tenfold higher than expected for the general population and suggest that dyscalculia, like other learning disabilities, has a significant familial aggregation,…

Classification of arithmetic disorders is predicated on neuropsychological features and associated learning disabilities. Assesses the compatibility of these classifications on a nonreferred, population-based cohort of children (N=139) with developmental dyscalculia. Concludes that children with dyscalculia and disabilities in reading and/or…

This study found that 331 Toronto (Ontario, Canada) adolescent and adult subjects with learning disabilities could be grouped into three subtypes: (1) arithmetic disability, (2) reading disability, and (3) reading and arithmetic disabilities. Each group differed significantly from the others on tests of reading, spelling, memory, and other…

Presented is evidence suggesting that many of the 6 percent of children who have difficulty with arithmetic suffer from a neurological development lag rather than an underlying deficit. Such pupils appear to favor the right cerebral hemisphere, which serves spatial functions, rather than the left, analytic half of the brain. (Author/KC)

This book explores how primary school children with dyslexia or dyspraxia and difficulty in math can learn math and provides practical support and detailed teaching suggestions. It considers cognitive features that underlie difficulty with mathematics generally or with specific aspects of mathematics. It outlines the ways in which children usually…

Examines the concept of number sense in mathematics learning, compares this concept to that of phonological awareness in reading, and urges application of existing research to improving mathematics instruction for students with mathematical disabilities. Reviews research on building automaticity with basic facts, adjusting instruction to address…
