Maya is a Mesoamerican civilization known for its writing, art, architecture, mathematical and astronomical systems. The beginning of its formation is attributed to the pre-classical era (2000 BC - 250 AD), most of the Mayan cities reached their peak in the classical period (250-900 AD). By the time the conquistadors arrived, it was in deep decline. The Mayans built stone cities, many of which were abandoned long before the arrival of Europeans, others were inhabited after. The Mayan calendar was also used by other peoples of Central America. The hieroglyphic writing system was used, partially deciphered. Numerous inscriptions on the monuments have been preserved. They created an effective farming system, had deep knowledge in the field of astronomy. The descendants of the ancient Maya are not only the modern Maya peoples who preserved the language of their ancestors, but also part of the Hispanic population of the southern states of Mexico, Guatemala, Honduras. Some Mayan cities are included in the UNESCO World Heritage List: Palenque, Chichen Itza, Uxmal in Mexico, Tikal and Quirigua in Guatemala, Copan in Honduras, Hoya de Seren in El Salvador.

The cultural history of this people is usually divided into three periods:

The first period (from antiquity to 317) is the time of the emergence of city-states, primitive slash farming, the manufacture of cotton fabrics, etc.

The second period (317-987) - the ancient kingdom, or the classical period - the time of the growth of cities (Palenque, Chichen Itza, Tulum) and at the same time the mysterious exodus of the population from them at the beginning of the 10th century.

The third period (987 - XVI century) - the new kingdom, or the post-classical period - the time of the arrival of the European conquistadors, the adoption of new laws, styles in life and art, the mixing of cultures, fratricidal wars, etc.

Education is an important part of modern life. Being educated means to know a lot of necessary and useful things for life, which is why every decent person studies at school. Originally Russian education starts from the early age. Children can start going to kindergarten from the age of two, but this is not a compulsory education. It depends on parents’ decision and child’s wish to attend this institution. However, school is mandatory. Every child starts going to school from the age of seven and till 16. Mandatory education in Russia is presented by three types of schools: primary, secondary and high. The primary school teaches its pupils elementary skills, such as reading, writing, counting. Many schools also offer foreign languages or some other special disciplines at this age. The most important period is the secondary school, which starts from the 4th or 5th grade, depending on school. This is the time when children start learning Biology, Geography, Chemistry, Physics, Computing, and many other new subjects. At the 9th grade children face a very important period in their life. They have to choose whether to continue school education, or to leave for other types of educational institutions, such as college, specialized schools and else. If the pupil decides to continue studying in high school, which lasts for two years, he can enter the university after school graduation. Of course, it’s only the general pattern of education in Russia, but there can also be some exceptions nowadays. For example, there are lots of special schools, where they pay attention only to particular subjects. Also, apart from state schools, there are a number of private schools, where education is not free of charge.
