Starting from the fifth grade, all schools regularly hold competitions in all basic subjects. This system has existed since Soviet times - the winners school stage participate in the regional Olympiad, then the city Olympiad, and so on up to international competitions. There are also Olympiads for high school students, which are held by famous universities. But little is known about the Olympiads for primary schools. But also junior schoolchildren there is a chance to test yourself. Moreover, for many children, it is with interesting Olympiad problems that their interest in a school subject begins.

"Kangaroo"

Item: mathematics.

How it is organized:“Kangaroo” is the most popular mathematical competition for younger schoolchildren (but it is also held for older children). Children from all over Russia and beyond participate in it; the Olympiad is held under the motto “Mathematics for everyone.” Every student can take part in a math competition without leaving their classroom. Schools that submit applications receive tasks for children and organize the Olympiad. All schoolchildren write "Kangaroo" on the same day once a year. The school sends the completed forms to the organizing committee, after about a month and a half to two months the results appear on the competition website, and they come to the school. As a result, the student will know his place in the school, in the city, and among all the participants in the competition. All participants receive 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 organized, 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 must also pay a small organizational fee (about 60 rubles).
