"Mind Games" for students in grades 5-9

In work we use addition,

Build - both honor and honor,

Let's add patience to skill,

And the amount will bring success!

Multiplication will help in labor,

So that the work is efficient,

Let's multiply hard work a hundredfold -

Our deeds will multiply!

Any of the following will help:

They bring us good luck

And that’s why we’re together in life

Science and labor are advancing!!!

Don't forget to subtract

So that the day is not wasted,

From the sum of effort and knowledge

We will subtract idleness and laziness!

Division actually serves us,

It will always wash us:

Who shares the difficulties equally,

Share the successes of labor!

Commandments of the competition

• Give your opponents nothing but tribute of admiration.
• If you lose, don’t be upset: next time you will win.
• If you win, don’t flatter yourself: next time you can lose.
• Don't lose your temper, otherwise nothing necessary will come of you.
• Trust in the fairness of the jury and remember: jury members are not sappers and can make mistakes many times.

So that the game goes as it should,

I am glad to present to the jury.

The jury is the highest executive body of the competition. All jury members are strong, healthy people, and therefore do not have the right to root for any team.

Our competition is judged by:...

Jury commandments:

• Don't rush to a quick conclusion.
• Get into command position.
• Resolve contradictions skillfully.
• Remember that truth is born in disputes.
• Don't make predictions about the winners.
• Do not abuse your rights.
• When counting points, look carefully at the sum of the numbers in the right and left columns. Think about how to move them so that the amounts are equal.

And let the struggle rage on,

Intense competition.

Success is not decided by fate,

But only your knowledge.
