متى نقول عن شخص ما ( أنه معاق في مجال الرياضيات ) ؟؟؟؟؟؟
Dyscalculia refers to a wide range of lifelong learning disabilities involving math. There is no single type of math disability. Dyscalculia can vary from person to person. And, it can affect people differently at different stages of life.
Two major areas of weakness can contribute to math learning disabilities:
 Visualspatial difficulties, which result in a person having trouble processing what the eye sees
 Language processing difficulties, which result in a person having trouble processing and making sense of what the ear hears
Using alternate learning methods, people with dyscalculia can achieve success.
What Are the Effects of Dyscalculia?
Disabilities involving math vary greatly. So, the effects they have on a person's development can vary just as much. For instance, a person who has trouble processing language will face different challenges in math than a person who has trouble with visualspatial relationships. Another person may have trouble remembering facts and keeping a sequence of steps in order. This person will have yet a different set of mathrelated challenges to overcome.
For individuals with visualspatial troubles, it may be hard to visualize patterns or different parts of a math problem. Language processing problems can make it hard for a person to get a grasp of the vocabulary of math. Without the proper vocabulary and a clear understanding of what the words represent, it is difficult to build on math knowledge.
When basic math facts are not mastered earlier, teens and adults with dyscalculia may have trouble moving on to more advanced math applications. These require that a person be able to follow multistep procedures and be able to identify critical information needed to solve equations and more complex problems.
What Are the Warning Signs of Dyscalculia?
Having trouble learning math skills does not necessarily mean a person has a learning disability. All students learn at different paces. It can take young people time and practice for formal math procedures to make practical sense. So how can you tell if someone has dyscalculia? If a person continues to display trouble with the areas listed below, consider testing for dyscalculia. Extra help may be beneficial.

How Is Dyscalculia Identified?
When a teacher or trained professional evaluates a student for learning disabilities in math, the student is interviewed about a full range of mathrelated skills and behaviors. Pencil and paper math tests are often used, but an evaluation needs to accomplish more. It is meant to reveal how a person understands and uses numbers and math concepts to solve advancedlevel, as well as everyday, problems. The evaluation compares a person's expected and actual levels of skill and understanding while noting the person's specific strengths and weaknesses. Below are some of the areas that may be addressed:
 Ability with basic math skills like counting, adding, subtracting, multiplying and dividing
 Ability to predict appropriate procedures based on understanding patterns—knowing when to add, subtract, multiply, divide or do more advanced computations
 Ability to organize objects in a logical way
 Ability to measure—telling time, using money
 Ability to estimate number quantities
 Ability to selfcheck work and find alternate ways to solve problems.
How Is Dyscalculia Treated?
Helping a student identify his/her strengths and weaknesses is the first step to getting help. Following identification, parents, teachers and other educators can work together to establish strategies that will help the student learn math more effectively. Help outside the classroom lets a student and tutor focus specifically on the difficulties that student is having, taking pressure off moving to new topics too quickly. Repeated reinforcement and specific practice of straightforward ideas can make understanding easier. Other strategies for inside and outside the classroom include:
 Use graph paper for students who have difficulty organizing ideas on paper.
 Work on finding different ways to approach math facts; i.e., instead of just memorizing the multiplication tables, explain that 8 x 2 = 16, so if 16 is doubled, 8 x 4 must = 32.
 Practice estimating as a way to begin solving math problems.
 Introduce new skills beginning with concrete examples and later moving to more abstract applications.
 For language difficulties, explain ideas and problems clearly and encourage students to ask questions as they work.
 Provide a place to work with few distractions and have pencils, erasers and other tools on hand as needed.
Help students become aware of their strengths and weaknesses. Understanding how a person learns best is a big step in achieving academic success and confidence.
