Mathematics in primary school is a very important subjects. In third grade, children learn to build logical chains of thought and teaching sequence. In the third class are starting to solve the first problem is not obvious. The importance of this subject is expressed in the further addition of the mind of the child. Mathematics allows us to develop the child's ability, which can then open it in the pursuit of science.
 
 The school curriculum in mathematics for third grade children to give an idea of ​​what are the units of measurement, the value of which is independent and which is the ratio of the other two variables. We study such a thing, which is the main basis on which further courses are built. One of these concepts is a fraction, giving the concept of infinity number. This problem is for children aged 10 years is not trivial and causes difficulties.
 
During the year, it is the first presentation of the figures, which will later be used in geometry. These skills develop in a child's geometric thinking, attentiveness, that is the most important in the development of mathematical mindset. But the curriculum could not devote sufficient time to address such problems. This requires extra classes in math class 3, which further elaborates on the basics of the theoretical component of the geometrical figures, but also to develop spatial thinking, which requires a more individual approach to each child, that becomes difficult if the lessons of this discipline are in the general education classroom. Extra classes in math class 3 help secure repeat material passed at school and help the child to learn the material, which is the arithmetic, algebraic and geometric components in one-piece object, pointed at each of its parts. But most importantly, these studies are needed for a more deliberate study of the subject, which increases the interest of the children themselves to the discipline.
