Mathematical KVN
Mr. X
(for students in grades 6 - 7)

Preparation
Draw.
Prepare cards with the letters X1, X2, X3 according to the number of participants and offer to pull out of the blind hat for each participant. To one team - all X1, to another team - X2, and to the third - X3 (teams are completed randomly).
Homework: "X-mixture"
The team selects 1 from Latin letters and composes a song, a verse, a ditty about it and thinks through the elements of the costume - hats, masks, collars.
As homework, viewers can be asked to draw a portrait of some letter of the Latin alphabet, presenting it as a person, animal, plant, etc. These drawings can be used to decorate the hall.
Equipment: cards - X tokens for correct answers - 100 pieces, cards with the letters: Z, N, M, X, S, F (for the X-film competition); test and three blank cards for team answers (the team must have a pack of felt-tip pens on the table to quickly write in answers), 1 answer sheet for the jury; 3 equation sheets for teams and 1 answer sheet for the jury; X-chance question sheet for the presenter.

Event progress

Competitive part.

1. 1. The "X-Test" (see Annex 1)

Host: Questions and 4 answer options will appear on the slide You need to choose the correct answer and enter it in your blank card At the end of the test, teams will submit their cards to the jury.
In the meantime, the jury is checking your answers with their homework "X-mixture" shows the X1 team.

1. 1. "X-List"

Host: Each team receives 10 equations to solve, you write the answers into a sheet and hand them over to the jury.
While the jury checks your answers, their homework "X-mixture" shows the X2 team.
(Equation options can be selected taking into account the capabilities of the guys and the material covered from the simplest to the most complex)

1. 1. The X-Film

Host: Now you get a card with a Latin letter and remember the film or movie hero where this letter appears (as a signature, costume element, hero name, etc.). In addition, you can offer your own options.
