Graphical Arithmetic for Learners with Dyscalculia 
University West, Department of Economics and IT, Division of Media Production.
2005 (English)In: Proceedings of the 7th international ACM SIGACCESS conference on Computers and accessibility , New York: ACM [Association for Computing Machinery] , 2005, p. 214-215Conference paper, Published paper (Refereed)
Abstract [en]

We propose a model for arithmetic, based on graphical representations, to complement the symbolic language of mathematics. The focus is conceptual understanding of arithmetic. We argue that the graphical model supports understanding concepts known to be difficult for learners with dyscalculia, such as number-sense and decimal system. The proposed graphical representation share properties of the decimal system, but is closer to the semantic representation of numbers vital to the number-sense. The model is evaluated with school-children, but needs to be further tested by learners with dyscalculia.
