The study aimed at investigating the role of concrete manipulatives materiales, in comparison to the traditional adopted methods of teaching, in enhancing the achievement levels of visually handicapped pupils in mathematics. The study focused exclusively on the unit of algebraic terms and expressions studied by the first preparatory pupils in Al-Noor Schools in 2002-2003. The problem of the study was formed in the following question: | The study aimed at investigating the role of concrete manipulatives materiales, in comparison to the traditional adopted methods of teaching, in enhancing the achievement levels of visually handicapped pupils in mathematics.
