In the webinar, you will learn about affordable and fun ways to increase parental involvement in the meeting. Parental involvement can be not only passive, but sometimes protesting opinion of the teacher. Create conditions, use soft forms of invitations to work and find like-minded people in the person of parents.

Some lessons may seem boring to children. And then discipline begins to suffer in the classroom, the students quickly get tired and do not want to take part in the discussion.

Case studies were created to combine educational school knowledge with urgently needed competencies, such as creativity, systemic and critical thinking, commitment and others.

Thanks to the cases, you will be able to help the student to receive benefits and pleasure from studying, to cope with his personal problems!

If you are a teacher, then of course you wondered: what books you need to read in order for your work to bring joy and satisfaction? There is no doubt that now you can find a lot of information on this issue on the Internet. But such a variety is very difficult to understand. Finding out which books will really become your assistants will take a long time. In this article, you will learn about which books every teacher should read.

The clarity of the material motivates elementary school children to solve the educational problem and maintains interest in the subject. Therefore, one of the most effective teaching methods is the use of flashcards. The cards can be used in teaching any subject, including in hobby activities and in extracurricular activities. For example, the same cards with vegetables and fruits are suitable for teaching counting in math lessons, and for studying the topic of wild and garden plants in the lessons of the world around.

Conversation-workshop for junior schoolchildren "The globe on the table" Goals and objectives: acquaintance with the history of the appearance and use of the globe and geographical maps; development of motivation for learning, logical thinking and the ability to solve the simplest logical problems. Equipment: desktop globes, various types of physical maps, atlases. The teacher tells the children about the globe.

And in ancient times, people traveled little: there was no modern transport, moreover, they did not even know where to go. Our distant ancestors knew little about the planet Earth, on which we live. Over time, they learned to build first small boats, and then ships on which they could go on distant wanderings across the seas and oceans. These wanderings continued for many days and nights. How did the sailors not go astray? What helped them travel? (Answers-assumptions of children.) In those distant times, which I am telling you, sailors were guided by the stars. But the stars appear only at night and only in good weather. During daylight hours and in bad weather, travelers were helped by a globe. Not a single ship went sailing without a globe. What is a globe, you know? (Answers of children. The teacher demonstrates a globe; children examine it.) Look - this is the globe of our planet Earth. The globe was invented and made by people. Looking at the globe, we can learn a lot about our planet. For example, what shape is the Earth? Is there land on it? Is there a lot of water on our planet? There are very interesting globes in the world. The largest of these was made in France. Our entire group could fit inside it (the diameter of the globe is 13 meters). This globe is very heavy, weighing as much as a modern bus. Our country also has amazing globes. One of them is located in St. Petersburg. Globe diameter - 3 meters; he was taken out of Germany by Peter the Great; on its outer surface - a map of the Earth, and on the inner - the starry sky. Another large globe can be seen in Moscow, on the site in front of the planetarium. Nowadays, a wide variety of globes are made. One of them is in front of you. Now I will show you the place where we live (show). This year we will learn a lot more about our planet: the globe will help us in this. ...

The giant ball, created back in 1998, is exhibited in the spacious pavilion of the DeLorme headquarters in Yarmouth, USA.

People started creating maps a long time ago, and these maps were different. So, the inhabitants of one of the southern islands weaved cards from dried leaves, and villages, rivers, mountains, sea routes were designated by shells, which were attached to a wicker base. They treasured their cards very much, never took them with them on sea voyages, so as not to lose or damage them during a storm. The islanders memorized the map before setting off. Nowadays, maps are printed on paper. People did not immediately create a map of the world, because in ancient times they did not know the planet on which they lived. It took many, many years. A map is an image, a drawing, which most accurately represents all the features of the area: lands, countries, cities

History of the issue The shape of the Earth - our home - worried mankind for a long time. Today, every schoolchild has no doubt that the planet is spherical. But it took a long time to get to this knowledge, going through church anathemas and the courts of the Inquisition. Today people are wondering who proved that the earth is round. After all, not everyone liked the lessons of history and geography. Is the Earth round? Different peoples had their own ideas about the structure of the world and space. Before answering the question of who proved that the Earth is round, you should familiarize yourself with other versions. The earliest theories of world building argued that the earth was flat (as people saw it). They explained the movement of heavenly bodies (sun, moon, stars) by the fact that it was their planet that was the center of the Cosmos and the Universe. In ancient Egypt, the Earth was represented as a disk lying on four elephants. They, in turn, stood on a giant turtle swimming in the sea. The one who discovered that the Earth is round was not yet born, but the theory of the sages of the pharaoh could explain the causes of earthquakes and floods, sunrise and sunset. The Greeks also had their own ideas about the world. The earth's disk in their understanding was covered with celestial spheres, to which the stars were tied with invisible threads. They considered the moon and the sun gods -. Science and the Church The Vatican admitted that the Earth is round rather late. Then, when it was impossible to deny the obvious. Early European writers initially rejected this theory as contrary to Scripture. At the time of Kozma, Indikoplevst described the Earth as a kind of box, at the bottom of which a stronghold inhabited by people rested. The sky served as a "cover", but it was motionless. The moon, stars and sun moved as angels across the sky and hid behind a high mountain. The Kingdom of Heaven rested over this complex structure. An unknown geographer from Ravenna described our planet as a flat object surrounded by an ocean, endless desert and mountains, behind which the sun, moon and stars hide.

Pythagoras said that the earth is round, but Galileo Galilei was the first to prove it theoretically. , the purpose of which was to go around the entire globe. Magellan himself at that time was still not sure of the happy end of the voyage, since the thought of the spherical shape of the Earth was only a theoretical assumption, but the journey ended successfully - and it was proved that the Earth is round.

The first round-the-world expedition of Magellan 1519-1522. Of the 265 people who went on a round-the-world voyage under the leadership of Magellan on September 20, 1519, only 18 sailors on September 6, 1522 returned on the last of the ships, sick and exhausted. Instead of honors, the team received a public repentance for one lost day as a result of moving around the time zones around the Earth in a westerly direction. So the Catholic Church punished the heroic team for a mistake in celebrating church dates.

Going outside and looking around, anyone can be convinced: the Earth is flat. There are, of course, hills and valleys, mountains and ravines. But in general it is clearly visible: flat, sloping along the edges. The ancients figured out this long ago. They saw the caravan disappearing over the horizon. Climbing the mountain, observers noticed that the horizon was expanding. The inevitable conclusion followed from this: the surface of the Earth is a hemisphere.

You will look into the sky and see the stars of the Zodiacs in life, space will give us Like destinies together in the space of the planet You will only receive answers on Earth Because the Earth is the base for the worlds of the Universe On this planet you are not the first For large worlds and civilizations That light, without all the abstractions So that we love, the blue planet And so that we give life, we are for the Earth - this Like a dear mother, loves and cherishes If the winter cold, she will warm everyone After all, she will not give offense, all the children dear In space distant, for she loved all of us and warmed her soul Our mother planet, warmed her heart
