To conduct zan
zibar it is necessary a rather limited jury, unlike other events, so the seniors in the league will choose their assistants themselves. But anyone wishing to help can arrive at this event.

Mathematical Zanzibar September 16, 2018

We will start olympiad competitions this year with a mathematical zanzibar. It is included in the program of the XV tournament of mathematical battles named after Lesya Rubleva. As in all recent years, the tournament (including mathematical zanzibar) will be held in four leagues: the youngest (not older than 7th grade), junior (8 classes), middle (9 classes) and senior (10 – 11 classes). Permissible, but not desirable, the participation of some students or entire teams in a higher parallel compared to their true learning class. The event will be held at the Faculty of Mechanics and Mathematics (M) and the Faculty of Computer Science and Cybernetics (K) of Taras Shevchenko National University of Kyiv at Glushkov Avenue 4d and 4e.

We will present the exact schedule of the event later upon registration. We would like to emphasize that two leagues will start the competition at 10:00, and two more at 10:30.

At 10:45 a.m., a meeting with teachers will begin. We ask everyone who participates in this meeting to read the program of our nearest events so that we can adjust it at this meeting with teachers.

As always in recent years, we have certain limits on the number of teams that will be able to participate in zanzibar. If it is not possible to place all registered teams under normal conditions, the organizing committee may reduce the number of teams in certain leagues by reducing the number of teams from educational institutions that will declare the largest number of teams. We will inform the educational institutions about our decision to reduce the number of their teams in the event, but to decide which teams to leave and which to remove (or simply reformat the compositions of all teams) will be decided by teachers – representatives of the educational institution. The team registration speed should not affect this decision.

From each educational institution you can declare:

no more than 3 teams in the youngest league,

No more than 2 teams in junior,

no more than 2 teams of medium and

no more than 4 teams in the senior.

Participation of teams from an educational institution that does not exceed these quotas is free of charge. For each additional team above the above quota, which will be allowed to participate, it will be necessary to contribute 200 UAH to the fund of our tournament at the teachers' meeting.

It is undesirable not to arrive at the zanzibar teams for which the organizing committee has participated. It is completely impossible to participate in the event of teams that were not registered at all, or those for whom the decision to refuse was made regarding their participation. Similarly, it is not possible to participate in one team of more than 6 students.

I ask that the registration be carried out by adults responsible for this team during the event. They should decide if fewer or more participants arrive, not the organizing committee or jury of the tournament.

I also ask teachers to help children get acquainted with the rules of "mathematical zanzibar" in advance so that children do not lose points because of misunderstanding or misinterpretation of the rules. The main nuances of Zanzibar are that the team in full solves all tasks in random order. As soon as she believes she has solved the problem and is ready to give the jury an answer, she passes the recorded response to the jury. Then there is the recalculation of points in all teams for this task. Let me remind you that with the correct answer of the next team, everyone who has solved it correctly receives 1 point less, and with the wrong answer – 1 point more. Therefore, unlike other competitions, with your wrong answer, you do not lose your chances to score points on this task, but also increase the achievement of opponents. Do not forget that if there are several correct answers in the task, then only guiding them all is counted.
