Mathematical Abilities of Children With Specific Language Impairment

Abstract

A 2-year follow-up of the mathematical abilities of young children with specific language impairment (SLI) is reported. To detect the nature of the difficulties children with SLI exhibited in mathematics, the first- and second-grade children's performance was compared to mental age and language age comparison groups of typically developing children on a series of tasks that examined conceptual, procedural, and declarative knowledge of mathematics. Despite displaying knowledge of many conceptual aspects of mathematics such as counting plates of cookies to decide which plate had "more," children with SLI displayed marked difficulty with declarative mathematical knowledge that required an immediate response such as rote counting to fifty, counting by 10's, reciting numerals backwards from 20, and addition facts such as 2 + 2=?. Moreover, children with SLI performed similarly to their cognitive peers on mathematical tasks that allowed children to use actual objects to count and on math problems that did not require them to exceed the sequence of numbers that they knew well. These findings offer further evidence that storage and/or retrieval of rote sequential material is particularly cumbersome for children with SLI.
