He has noticed that, the child in mathematics has a problem with the numbers, confuses the mathematical signs (more or less), misunderstands the composition of the number, does not understand the content of the tasks without external help; It is likely that the child has dyscalculia.

What is dyscalculia?

Dyscalculia is a learning disorder that affects children's ability to learn mathematics. Children with dyscalculia may have difficulty understanding the concepts related to numbers or to use the "plus", "minus" symbols or functions required in mathematics.

However, this is not a purely school problem. This disorder can also cause problems in daily life. As a rule, this disorder appears in children of preschool and primary age, but it can also occur in an adult.

Children who have learning difficulties have problems with many aspects of mathematics.

They often have difficulties with the concept of quantity or the mathematical categories of "more", "less". They may not understand that the number 5 matches the word "five" (these skills are often called numerical skills).

Children with dyscalculia also have problems with the mechanics of mathematics, such as the ability to memorize mathematical facts. They can understand the logic of mathematics, but they do not understand how and when to apply what they know to solve mathematical problems.

They often also have problems with functional memory. For example, they may have difficulty keeping numbers in memory when solving multi-step math problems.

## Terms that denote problems with mathematics.

The term dyscalculia is not well known. Therefore, this disorder is called differently. Some schools view dyscalculia as a normal school failure. This is sometimes called a mathematical disorder. You can even hear how children and parents call it mathematical dyslexia.

## Symptoms of dyscalculia:

Source

❇ difficulty in distinguishing and writing numbers;

❇ inability to determine time and navigate in hours, minutes, seconds;

❇ lack of coordination of fine movements;

❇ the inability to determine the distance traveled, measure the length of the segment;

❇ the complexity of the perception of the concepts "less", "more";

❇ the impossibility of solving problems without illustrative support;

❇ difficulties to solve logical problems, perform actions with abstract categories;

❇ the inability to visually determine the number of objects, converting them into groups without recalculating them one by one.

## Causes of dyscalculia

**Mathematical phobia.**Some students have a negative learning experience in the past, which has developed doubts and fear of mathematical examples.**Bad processing of visual information.**At the same time, children can not accurately visualize the situation and the mathematical numbers in the problem. These violations are also called "non-verbal learning difficulties."**Inability to establish order.**Children with this difficulty can not remember the facts and formulas required for mathematical calculations.

## There are five different types of dyscalculia, these are the following

**Verbal dyscalculia:**difficulty in naming and understanding the mathematical concepts that are taught verbally. They can read or write the numbers, but not recognize them when someone else mentions them.**Practognostic dyscalculia:**difficulty in understanding abstract-mathematical concepts. They can not list, compare and manipulate mathematical operations.**Lexical dyscalculia:**There is a difficulty in reading mathematical symbols, mathematical expressions or equations.**Graphic dyscalculia:**It is the difficulty to write mathematical symbols.**Ideognostic dyscalculia:**They can not do mental operations without using numbers. He also has difficulty remembering mathematical concepts after learning them.**Operational dyscalculia:**There is difficulty in performing arithmetical operations or mathematical calculations, both verbal and written.

*"If an intervention is not carried out in time, the dyscalculia can cause repercussions in the academic performance and in the daily functioning of the children who suffer it, having consequences in their current and future well-being. The faster you know the child's difficulties, the easier it will be to get the help you need."*
