"Letidor" has compiled a review of the Olympiads for elementary school, thanks to which you can check the level of knowledge of the child in mathematics, as well as Russian, English and German.
Starting from the fifth grade, Olympiads in all major subjects are regularly held in all schools. This system has existed since Soviet times - the winners school stage participate in the regional Olympiad, then the city and so on up to international competitions. There are also Olympiads for high school students, which are held by eminent universities. But little is known about the Olympiads for elementary school. But also junior schoolchildren there is a chance to test yourself. Moreover, for many children it is with interesting Olympiad problems that interest in the school subject begins.
"Kangaroo"
Thing: mathematics.
How organized:"Kangaroo" is the most massive mathematical competition for younger students (but it is also held for older children). Children from all over Russia and not only participate in it, the Olympiad is held under the motto "Mathematics for All". Each student can take part in a mathematical competition without leaving his class. Schools that have submitted applications receive assignments for children and organize the Olympiad. All students write "Kangaroo" on the same day once a year. The school sends the completed forms to the organizing committee, after about one and a half to two months the results appear on the competition website, they also come to the school. As a result, the student will find out his place in the school, in the city and among all the participants in the competition. All participants receive memorable souvenirs and certificates of participation from the organizers, and winners of all levels receive diplomas and more significant prizes.
How to participate: The organizer from the school must submit an application for participation. In most schools in our country, the competition has already been established, and there is such an organizer. If not, then any teacher or even a parent can become the organizer. The organizer collects applications from schoolchildren, everyone who wishes must also pay a small organizational fee (about 60 rubles).
Any child from 2nd grade can participate.
All information on the competition, including examples of tasks from previous years, is available on the website http://mathkang.ru/.
The competition is held in the third week of March, the next one will be held on March 19, 2015.
Olympics primary school v different time have always existed. In different schools, different cities. As long as there are enthusiastic teachers, there will be various Olympiads.
In 1995, a circle of primary classes was opened for the first time at the Small Mekhmat. In the spring of 1996, for the first time, the idea arose to hold something like an Olympiad for the members of the circle. All sorts of mathematical holidays have already been held, but there the guys participated in teams of different ages, but I wanted to give them the opportunity to work individually.
And for the first time in March 1996, the Primary School Olympiad of the Small Mekhmat was held. The Olympiad was held in an oral-written format. That is, the task was written on the blackboard and the children were asked to write it down on paper. But, since very young children also participated in the Olympiad, after the child declared that he had solved and wrote down the problem, the teacher approached him (then it was the head of the circle - Elena Yuryevna Ivanova) and asked to explain what was written in the solution.
Then, in 1996, only 15 people participated in the Olympiad, and no one was awarded prizes, the winners were given certificates and shook hands. But the guys were still happy.
Unfortunately, the conditions of the first Olympiads have not been preserved. We will be grateful if suddenly someone in the archives finds the conditions and he will share with us.
Inspired by the success, in the spring of 1997 it was decided to hold the Olympiad again. This year, the texts of the problems were typed, and each participant received his own condition. If in the first Olympiad the conditions were the same for everyone, then this year there were two options: for grades 1-2 and for grades 3-5. (During these years, a gradual transition to a four-year system of education in elementary school began and grade 4 in many schools began to disappear, turning into grade 5.) Already 22 schoolchildren took part in the second Olympiad, and not only circle members, but also several schoolchildren who did not participate in the work of the circle. So to speak for the company with friends.
The circle gradually grew, gradually turning into not one, but several. In 1999, for the first time in the Primary School Olympiad, a variant appeared separately for the 5th grade. Then the 5th grade olympiads were not held and the 5th graders - the participants of the olympiad were exclusively members of the circle.
Later, the 5th grade Olympiad spun off into an independent one and changed a lot. You can read about it in the 5th grade Olympiad section. Here we will continue the conversation about elementary school.
Until 2005, the Olympiad was held at the Small Mechanics and Mathematics of Moscow State University, being in fact a competition for circle members. In March 2005, for the first time, the Olympiad moved from the walls of Moscow State University to DNTTM and occupied an entire floor on one of the Sundays. Then for the first time there were already 85 participants and the work did not have time to check in one day. At the same time, for the first time, together with the diplomas, the first prizes from the DNTTM and the Small Mekhmat appeared.
The story about the Primary School Olympiads will definitely be continued...
