Currently, there are a large number of different Olympiads designed for students primary grades... The significance of these Olympiads is very great for them: it broadens their horizons, instills a desire for knowledge, etc.
Excitement and fear await pupils while participating in city and regional Olympiads. All this can adversely affect their performance. Under conditions of stress, the participants of the Olympiads may not cope with elementary tasks for them. In order to avoid this, students need to early years accustom to such conditions. It is best for students to start participating in various Olympiads back in primary school... Olympiads for elementary school students not only accustom children to stressful conditions and effective work at such moments, but also allow them to broaden the horizons of children, to form an interest in academic subjects, deepen knowledge.
The Olympics are also good because they are in lung shape competitions, form in children the desire to show themselves, become better, begin to understand better in any area and achieve their first successes in life. Currently, there are many ways to conduct Olympiads for primary school students. Primary school teachers themselves prepare tasks for olympiads in various subjects (mathematics, reading, cognition of the world, etc.) and conduct them between the entire parallel.
The development of computer technology has contributed to the emergence of a new type of Olympiads: various intellectual Internet contests. Schoolchildren from different cities can take part in such competitions at the same time, the results of such Olympiads will be obtained in as soon as possible (right after the answers are processed by the computer - it may take only a few minutes), which will save teachers' time, which they usually spend on preparing assignments and checking the work performed by the contestants.
There are also various distance Olympiads, the participation of which consists in completing the proposed tasks and sending them for verification (by mail, by e-mail and etc) . One of the striking examples of such Olympiads is All-Russian Olympiad for pupils of grades 1-4, which was named "House of Semignomics" Those wishing to take part in this Olympiad apply to certain terms, then they take assignments on the site on which the Olympiad assignments are published, perform them and send them for review. After summing up the results of the Olympiad, all participants receive various diplomas: Diplomas of winners, prize-winners and participants.
Another example of distance intellectual marathons is the Unik-Um Olympiad. This Olympiad is All-Russian, its preparation is carried out on the basis of Omsk state university them. FM Dostoevsky Center for Distance Technologies in Education "Distance +". Participants in this Olympiad are divided into 2 age categories: students in grades 1-2 and 3-4. Participants can choose one of the proposed directions for participation: multidisciplinary (interdisciplinary) Olympiad, Olympiad in literary reading, computer science, Russian language, the world around them, etc. According to the results of the Olympiad, participants will receive diplomas and certificates.
Very interesting intellectual contests held among pupils of both senior classes and elementary schools are "Russian Bear", "Golden Fleece", "Kangaroo", "EMU", "Clever", etc. The Russian bear cub is an international intellectual game in linguistics, which annually admits students from schools in Russia, Armenia, Kyrgyzstan, Ukraine, Moldova, Kazakhstan, India, United United Arab Emirates, Finland, Latvia, Bulgaria and other countries. Distinctive feature of this intellectual competition is that the tasks in it are presented in a fun game form, which makes children interested in the subject, they have a desire to find answers to one or another question that they could not solve on their own. In this regard, schoolchildren begin to read more, take an interest in issues related to linguistics, and thus broaden their horizons. It is very important that the tasks of this intellectual competition are divided into different groups according to the level of difficulty, which makes them accessible not only for gifted children, but also for ordinary students. general education schools... All pupils from 2nd to 11th grade can take part in the competition "Russian Bear Cub".
An analogue of the Russian Bear Cub competition is the Kangaroo intellectual competition in mathematics. Usually, schoolchildren rarely like math, most often children perceive exact sciences as something boring and even boring. To solve this problem and allows participation in the competition in mathematics "Kangaroo". The tasks of this competition, presented in a playful way, stimulate children's interest in mathematics. Intellectual competition "Golden Fleece" is an analogue of "Russian Bear" and "Kangaroo". This competition is held with the aim of instilling an interest in history and culture in children.
The intellectual competition EMU is designed for primary school students. There are 3 directions in which primary school students can take part in this competition. The first direction is EMU-Erudite. Participation in this competition will help students show their knowledge in all subjects studied in primary grades... During their participation in the competition, students will also be given the opportunity to demonstrate speed, courage and dexterity. The second direction is the EMU specialist. By participating in this competition, having completed the tasks of 6 rounds, students can demonstrate their knowledge of Russian and english languages, mathematics, literary reading, computer science and knowledge of the surrounding world. The third area is Creative teams. In this competition, children take part in teams of 5 people. Students in grades 1 and 2 participate separately from students in grades 3 and 4. By participating in such a competition, students are given the opportunity to demonstrate their creative skillsby preparing a project and submitting it. In addition, teachers under the "EMU-Marathon" project are given the opportunity to order a newspaper for students (for students of grades 1-3), "intellectual vitamins" (for grade 1 students) is a set of various tasks that contribute to the development of children logical thinking and other intellectual abilities, children's educational magazine "Adventures of Emu", a set of various tasks for students in grades 1-2 and 3-4.
It is very important to start teaching kids about research as early as possible. This ability will be simply necessary for them in the course of their studies in the future. In Russia, there is only one competition that allows primary school students to conduct research. This competition is called “I am a researcher”. This competition is held annually to develop skills in elementary school students. research work, the ability to observe various objects and processes, analyze them, build any hypotheses, learn to confirm or refute them in the process of research and, finally, draw conclusions from the research. In addition to all of the above, the intellectual competition allows junior schoolchildren to realize their creative abilities, and also contributes to the formation of students' interest in various sciences, allows them to understand them in more depth, etc.
In our age of intensive development information technologies it is extremely important to be fluent in computer technology. Interest in the in-depth study of a personal computer and work with it allows the development of the Infoznayka competition, which is held in a playful way. This competition is analogous to "Russian Bear" and "Kangaroo". In the Infoznayka competition, children are given the opportunity to compete in the knowledge of a personal computer, in the ability to work with it. Within the framework of the children's Internet festival "Umnik", many different online contests are held: games - a marathon (to complete tasks in a certain amount of time), a cinema park (looking for actors according to the description in in social networks), BEETLE (passing the labyrinth), night watch (solving the greatest number of problems), etc. In addition to various intellectual marathons for primary school students, an all-Russian competition "Man and Nature" is held. By participating in this competition, students can demonstrate their knowledge in the field of knowledge of the world, the connection of a person with environment, natural science, ecology and other related sciences.
In the primary grades of Russian schools, a heuristic Olympiad called "Owlet" is held annually. The main goals of this Olympiad are to identify gifted children in elementary grades, which will allow them to further develop their intellectual abilities, to form students' interest in learning in general or in more in-depth study of individual subjects. This Olympiad is held in two stages, according to the results of which the winner is determined. Each of these Olympiads will help develop the intellectual potential of the younger generation.
Primary school Olympiads, of which there are a lot now, allow with early childhood to identify children with good intellectual inclinations. This will further contribute to the development of abilities in these children.
