The importance of preschool education for a child's development should not be underestimated. In my opinion, knowledge that children receive in preschools, develop the basics of social adaptation, a positive attitude to work, and the correct value system. Preschool education helps a child to develop in a variety of ways in accordance with needs, aptitudes, physical and mental characteristics. This is an important component in the education system. I work according to the Montessori system- balanced pedagogical technology, which has been demonstrating excellent results for 100 years! Being in an adapted Montessori environment, the child understands that is capable and intelligent enough to do many things on his own. As an English language teacher, I can say that a child's speech determines intellectual, communicative and general cultural level. So, during my lessons, I focus on enrichment of vocabulary, phonetic and grammatical development, and activation of dialogical and monological speech. If speak about Mathematics lessons in preschool education I think that all children have start to learn mathematics very naturally: first perceives numbers, formulas and symbols visually and tactilely, and only then put it in mind as abstract concepts.
