CORSO, Luciana Vellinho  e  DORNELES, Beatriz Vargas. Number sense and learning difficulties in mathematics. Rev. psicopedag. [online]. 2010, vol.27, n.83, pp. 298-309. ISSN 0103-8486.

The article focuses on number sense, a key concept for understanding learning difficulties in mathematics. Through a review of international and national literature, the main topics around the theme are highlighted: definition, origin, intervention and assessment. The article presents the Number Knowledge Test, developed by Okamoto e Case (1996), suggested by the literature as a good instrument to measure number sense. Finally, it presents the implications of studying this concept to the prevention of mathematics difficulties and to research in this field.
