The crucial role of language in mathematical development

Basic mathematics skills build on nonverbal number sense But these innate non-verbal skills are insufficient to develop symbolic exact number concepts and to learn arithmetic. Language development allows the acquisition of number words and math vocabulary, crucial for developing basic exact number concepts and arithmetic skills. This presentations highlights five key aspects on how language influences mathematical development. First, language is a building block for basic math skills. Second, number naming systems affect number transcoding. Third, multilingual students calculate better in the language in which they have learned numbers. Forth, children's home language influences their mathematics achievement. And finally, the mastery of the language of instruction has a strong impact on mathematics achievement. The implication of these key aspects are discussed with regard to education and instruction in schools.
