Learning Disability with Impairment in Mathematics - click link

A learning disability with impairment in mathematics, (formerly referred to as Dyscalculia) is a broad category of life-long difficulties related to calculation, spatial relationships, timekeeping and other mathematic functions. There is no easy single definition of Dyscalculia at this time. Since the disability varies so much in its presentation, the effects Dyscalculia may have on individual development can be just as varied. For example, two individuals with a learning disability with impairment in mathematics may have varying degrees of math comprehension and performance. In some cases, short term memory may be affected. 

Warning Signs and Symptoms

Symptoms of a learning disability with impairment in mathematics do not show significant change as the individual ages. According to the DSM-V, young children, elementary-age children, adolescents, and adults tend to exhibit similar difficulties, including:

• Number sense
• Memorization of arithmetic facts
• Accurate or fluent calculation
• Accurate math reasoning
