"Math Quiz"
Class: 11A, 11B.
Teacher: Erokhina N.E.
Goals: Strengthen students' interest in studying mathematics, broaden students' horizons, and instill a desire to win and achieve new results.
Teacher: Guys, today we will give you a math quiz. It will include various sections on mathematics, entertaining questions and tasks, and even tests. At the end of our event, we will find out which team knows the history of arithmetic and geometry better, is more attentive and smarter. You will learn something new for yourself and remember what you already knew before. So let's get started!
1. Teams read poems about mathematics (instead of greetings).
1) 11A:
Why is there solemnity around?
Do you hear how quickly the speech stopped?
This is about the queen of all sciences
We start this evening.
It is no coincidence that she is so honored
It is given to her to give answers,
How to do a good calculation
To build a building, a rocket.
There is a rumor about mathematics
That she puts her mind in order,
Because good words
People often talk about her.
Mathematics, you give us
To overcome difficulties hardening,
Young people learn from you
Develop both will and ingenuity.
And for the fact that in creative work
You help out in difficult moments,
We are sincere to you today
We send thunderous applause!
Quiz on the history of arithmetic.
1) Who owns the words: Mathematics is the queen of sciences, and arithmetic is the queen of mathematics?
2) Is the name Arabic numerals correctly applied to our modern numerals?
3) Why was the method of division that we now use called “golden division” in the Middle Ages?
4) What books by M.V. Lomonosov called “the gates of his learning”?
5) Find out, without leading to a common denominator, which fraction is larger:
20/21 or 21/22?
6) Point A is located at a distance of 60 km from point B. at the same time, two bicycles left these points towards each other at a speed of 15 km/h. Together with the first cyclist, a wasp flew out from point A, its speed was 20 km/h. The wasp overtook the first cyclist and flew towards the second, who had left point B. Having met him, she immediately turned back and flew towards the cyclist, who had left from point A. Having met the cyclist, she again flew towards the second cyclist. And so she continued to fly back and forth until the cyclists met. Then she calmed down and sat down on one of them’s cap. How many kilometers did the wasp fly?
7) Three cats catch three mice in three minutes. How many cats does it take to catch 100 mice in 100 minutes?
8) How did Western Europe become familiar with Russian abacus?
9) Which two natural numbers, if you divide the larger one by the smaller one, give the same result as when multiplied?
10) Who is considered the inventor of decimal fractions?
11) What is “abacus”?
Answers:
1) These words belong to the famous mathematician Carl Friedrich Gauss (1777-1855), who worked in the field of number theory.
2) Modern numbers and the modern number system were invented in India. All number systems before the Indian system were extremely inconvenient. The Indian number system spread throughout Europe from the Arabs and the numbers were called “Arabic”. It would be more correct to call them “Indian”.
3) Before the introduction of the Indian number system and zero in Europe, division was a very difficult operation. There were many different methods of division, and each was very cumbersome. In the middle of the century there was even an academic degree “master of division”. Therefore, when in Europe they became acquainted with the Indian method (the modern method of division), it was called “golden”.
4) “The gates of your learning” M.V. Lomonosov called “Arithmetic” by L.F. Magnitsky and “Grammar” by M.G. Smotritsky. The publication of Magnitsky's book in 1703 was an important fact in the history of mathematical education in Russia. This was the first original Russian textbook on mathematics. The real name of the author of "Arithmetic" is unknown. Peter I talked with him many times about the mathematical sciences and was so delighted with his deep knowledge, which attracted people, that he called him a magnet and ordered him to “write Magnitsky.”
5) The second fraction is large, since it lacks 1/22 to one, and the first one lacks 1/21.
6) The wasp flew as long as it took before the cyclists met, therefore it flew 40 km.
7) 3 cats catch one mouse in 1 minute, which means the same 3 cats will catch 100 mice in 100 minutes.
8) Russian abacus was brought to France and written about by the French mathematician Jean Victor Poncelet, who was a prisoner of war after the Patriotic War of 1812. He was delighted with the simplicity and convenience of this device.
9) The larger number will be any natural number, and the smaller number will be 1.
10) Dutch mathematician Simon Stevin. (1548 -1620)
11) Abacus - a counting board among the ancient Greeks and Romans, which was then used for arithmetic calculations in Western Europe until the 18th century. The principle of the device is similar to our accounts.
The jury evaluates the correctness and completeness of the answers (all answers are on the table of the jury members).
Quiz on the history of geometry.
1) What great creation of ancient Greek mathematics is the basis of the geometry textbook for high schools in all countries? Who is its author? When did he live?
2) In Ancient Egypt 4,000 years ago, land surveyors were called “rope pullers.” What does this name mean?
3) According to legend, which of the great geometers of antiquity said to the soldier who came to kill him, “Don’t touch my circles”?
4) What, according to legend, did Archimedes bequeath to carve on his tombstone?
5) on the building were inscribed the words: “Let no one who is not skilled in geometry enter here”?
6)Which theorem in the Middle Ages was called the “master of mathematics” and why?
7) Who is the creator of the first non-Euclidean geometry, which gave rise to many other geometries?
8) Who is the creator of the modern axiomatics of Euclid’s geometry?
9) name the great geometer and mechanic of ancient Greece who found the approximate value of 3 1/7 for the number “pi”
10) What famous problem is called “Delian”?
11) The letters are divided into groups as follows:
Group 1: A, D, L, M, P, T, F, Sh.
Group 2: B, E, Z, K, S, E, S.
Group 3: F, I, O, X, N
Group 4: B,G,R,U,C,H,L,Y,Y.
It is necessary to determine the principle by which this breakdown is made.
Answers:
1) All modern textbooks on geometry are based on the famous “Elements” of Euclid, written in the 4th century BC. Modern school textbooks are a much lighter version of the “Principles.”
2) Already in Ancient Egypt, a theorem was known, which later became known as the Pythagorean theorem, which was used to construct right angles on the ground using a rope triangle with sides 3,4,5 (Egyptian triangle). The sides of this triangle were tensioned using pegs stuck into the ground at the vertices of the triangle. This is where the name of the ancient land surveyors comes from.
3) These are the words of Archimedes (c. 287-211 BC), who died during the capture of his hometown of Syracuse by the Romans. He created a powerful throwing machine. His fame was so great that many legends arose about him that have survived to this day. one of them states that when the Roman soldiers arrived, he was busy solving a problem, a drawing of which was made in the sand. It was then that he uttered these words.
4) Archimedes is known for many inventions and discoveries in the fields of mathematics and mechanics. But most of all he valued his work on the properties of the sphere, cylinder and cone. Archimedes wanted the drawing of the theorem connecting the volumes of these geometric bodies to be depicted not in his tomb.
5) According to legend, these words were written at the entrance to Plato’s “Academy” (429-348 BC)
6) This name was given to the Pythagorean theorem in the Middle Ages. Instead of taking a math exam, the student had to take an oath. that he read the prescribed number of chapters of Euclid's Elements. In fact, no one made it past the first chapter, so the last theorem of the first chapter of the Elements (the Pythagorean Theorem) was called “Master of Mathematics.”
7) The author of the first non-Euclidean geometry is N.I. Lobachevsky. At a meeting of the Faculty of Physics and Mathematics of Kazan University on February 11 (23), 1826, Lobachevsky made a report on the fundamentals of geometry.
8) The famous German mathematician D. Hilbert (1862-1943).
9) Archimedes.
10) “The Delian problem” is a problem about doubling a cube, that is, about constructing a cube with volumes twice the volume of a given cube. there is a legend associated with it. In Ancient Greece, there was a pestilence on the island of Delos. When they contacted the oracle of the Delian temple, he ordered the altar to be doubled, then the gods would have mercy and the pestilence would stop. However, this problem turned out to be unsolvable. 6 Using a compass and a ruler, it is impossible to construct the side of a cube whose volume is twice the given volume.
11) the letters included in the first group have axial symmetry (and only axial symmetry), and their axis of symmetry is vertical. The letters of the second group have axial and only axial symmetry, but their axis of symmetry is horizontal. Letters of group 3 have central symmetry. Letters of group 4 are asymmetrical figures.
The jury evaluates the correctness and completeness of the answers.
