15 1C 2E 3A 4B 5D 2A 3D Discussion What is the universe?
What can I find in there? Why are people so fascinated by it? Would you like to fly to the Moon? Do you think that one day people will be able to travel to other planets? What are the biggest problems the scientists are solving right now? How would you count the distance between the Sun and the Moon? What is a black hole? Does it exist? How fast do the spaceships fly? What are some activities of the people in the spaceship? What can you say about the Sun? Can you say something about the other planets? What is the Milky way? What is a comet? What is a meteor? What kind of shapes can be found in the space? 1C 2E 3A 4B 5D 2A 3D Can you match these numbers? Neutral numbers a) -2, 2/3, 1,21 Integers b) –e, √2, π Rational numbers c) 1,2,3,... Real numbers d) 2i, -2+3i Complex numbers e) -2,-1,0,1,2,... Can you match these equations,read them aloud and draw the image next to the equation? Circle a) x y2 = 1 a b2 2. Ellipse b) x y2 = 1 Parabola c) x2 + y2 = a2 Hyperbola d) y2 = 4ax

16 Do you know the answer? What did people think about the shapes of the Earth? Did they always know the Earth was a sphere? Do you know any famous astronomers? Why did they have problems with the Church? What did people think about the Sun? What do people know about other planets and other galaxies? How do people find new planets? Where can people go to observe planets? What is gravitation? What is gravitation good for? Would life exist without it? What is an orbit? Does the universe finish anywhere? How did it start? What happened at the beginning? Do you think the universe will collapse one day? Do we need the Moon for anything? What is the eclipse? Do you like movies about „meteor falling on the Earth“? Is such a disaster possible? Can you comment these statements and facts? The geocentric model entered Greek astronomy in the 4th century BC. During this period, educated Greeks thought that Earth was at the center of the universe and the Sun, Moon, stars and other planets surrounded Earth. The application of the telescope by Galileo Galilei in 1609 questioned the very foundation of geocentrism. With the help of his telescope, Galileo defended, corrected and expanded the heliocentric model challenging Ptolemy’s geocentrism. Isaac Newton devised the law of gravitation in The law of gravitation explained the motion of planets. On a clear night, the naked eye can only perceive about 3000 stars. Our galaxy alone has an estimated 1011 to 1012 stars and there are probably more than 1012 galaxies in the universe. With this simple calculation, there might be more than 1024 stars in the universe. Even if you had the most sophisticated spacecraft that travels at the speed of light (speed of light=186,000 miles per second), it would take approx. 105 (one hundred thousand) years to cross the galaxy.

27 Discusstion How do we read time in English? Why do people need to know time? What would happen if people didn´t know time? What kind of clock do you know? How do we read dates in English? How do we read years and centuries in English? What is a calendar? What parts does it have and why do some years have 366 days? Can you read these times? 12: :20 3. 5: :30 8: :58 7. 12: :00 9: The teacher dictates the times and the students write: _______________ 2) ______________ _______________ 4) ______________ 5) _______________ 6) ______________ What do you think about these statements? Time on Earth is actually slowing down. Dinosaurs had to fit a full day’s work into just 23 hours. Cultural background affects our perception of time. The Soviet Union experimented with 5 and 6-day weeks between 1929 and 1931. Like all good things, time will come to an end….maybe? There is no time like the present. Until the 1800s, every village lived in its own little time zone, with clocks synchronized to the local solar noon. Time has not been around forever. Most scientists believe it was created along with the rest of the universe in the Big Bang, 13.7 billion years ago. Everyone experiences time differently. The past and future are equally real.

A square is formed by 4 angles. The length and width of a rectangular are the same. π is needed for counting the sphere. Right angle triangle means that one of the angles measures 80o. Symmetry means that both sides are the exact same when split in half. Similarity means that the objects look the same but might have different lenght and width. A vector is needed for counting triangles.

55 Famous maths quotes... what do you think about them?
If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is.  ~John Louis von Neumann Pure mathematics is, in its way, the poetry of logical ideas.  ~Albert Einstein The essence of mathematics is not to make simple things complicated, but to make complicated things simple.  ~S. Gudder Go down deep enough into anything and you will find mathematics.  ~Dean Schlicter Sometimes it is useful to know how large your zero is.  ~Author Unknown If there is a God, he's a great mathematician.  ~Paul Dirac Infinity is a floorless room without walls or ceiling.  ~Author Unknown One cannot escape the feeling that these mathematical formulas have an independent existence and an intelligence of their own, that they are wiser than we are, wiser even than their discoverers...  ~Heinrich Hertz You and maths When did you become interested in maths? Why did you decide to study it? What about your studies? Where did you study and how difficult was it? Why did you become a teacher? Say something about your school. Say something about maths in each grade – what do you teach there? Which fields of maths are the most popular and which ones are the least popular of all? Why do the children like / dislike maths? What kind of tool do you use during your lessons? How often do you test your students? What methods do you use to explain various fields of maths? What do you think about the „state maturitas“? Do you think everyone should take the state maturita from maths? Why is maths important for our future? How do you think young students should be attracted to mathematical universities? What jobs can the students do when they finish mathemtical universities? Which mathematical problems do you think scientists will be solving in the future? Do you think you will spend your life as a teacher of mathematics?
