Abstract
BackgroundMathematical skills have an important role in progress of the educational level of nations. Unfortunately, there are still some pupils in school with normal intellectual function, but they have different degrees of mathematical disabilities that really can fall apart their whole life.Dyscalculia is called number blindness. It is the name given to the condition that affects our ability to acquire arithmetical skills. In the Arabic language, there is a deficiency in tools for diagnosis of dyscalculia, so we conducted this study to formulate a test suitable for diagnosis of dyscalculia in Egyptian children via translation and modification of an American test (TOMA 3 test).ResultsThe modified test was highly significant in discriminating dyscalculic from non-dyscalculic Egyptian pupils regarding all items of the test.ConclusionThe Arabic version of TOMA-3 is valid and reliable for diagnosis of dyscalculia in Egyptian school-age children.

Mathematical skills have an important role in progress of the educational level of nations
By comparing the results of normal and affected groups, we concluded that the dyscalculic group performed worse compared with the control group regarding all items of the core subtest of modified Test of Mathematical Abilities—Third Edition (TOMA-3), and the difference between the two groups was statistically significant
The Cronbach’s alpha value was 0.915, which indicates an excellent degree of reliability for raw score
Summary
Mathematical skills have an important role in progress of the educational level of nations. It is the name given to the condition that affects our ability to acquire arithmetical skills. Some individuals commonly have some type of difficulty in acquiring basic mathematical concepts. This difficulty starts right at the base, and because it is not taken seriously, it escalates resulting in dyscalculia. Dyscalculia is a specific learning disability affecting normal development of school-level arithmetic skills that results from specific neurocognitive dysfunction [2]. It is a brain-based condition with a familial-genetic predisposition that makes it hard to make sense of numbers and mathematics concepts [3].
