Teacher: Sharikova Lyubov Nikolaevna



The sons drove for a long time, and they met a passer-by. "Is it far to the village?" - they ask "

"You have covered a third of the total distance - that's 6 kilometers" How many kilometers still need to be covered by the sons?


The sons drove to the village and went to the inn to rest.

They asked the hostess to boil potatoes, but they themselves fell asleep. The hostess cooked the potatoes, set the table and left.

Fedor woke up, ate the third part and fell asleep again. Then Yegor woke up, counted the potatoes, ate the third part and also fell asleep. Ivan woke up and ate a third of the remaining potatoes. Then all the brothers woke up and saw that there were 8 potatoes left in the cup. How many pieces did the hostess cook and how much more should each of the brothers eat so that everyone gets the same amount?


The brothers wandered for a long time until they reached the hut of Baba Yaga. They told her where and why they were going.

“Guess my riddles, then I'll tell you where to find living water and rejuvenating apples,” said Baba Yaga


Ducks flew: one in front and two behind, one behind and two in front, one between two and three in a row. How many ducks flew?

Which is heavier: a pound of iron or a pound of fluff?

The goose weighs 2 kg. How much will he weigh if he stands on one leg?


The brothers guessed all the riddles and Baba Yaga showed them the way to Koshchey the Immortal, and left Fyodor so that he could cut wood for her.

It takes 1 minute to cut one meter off a log. In how many minutes will he cut a five-meter log?


So they drove along the road along which Baba Yaga showed them. Ahead is the river. They see a peasant sitting on the bank of the river, who needs to transport a wolf, a goat and a cabbage.

Only one person can fit in the boat, and with him - either a wolf, or a goat, or a cabbage. If you leave a wolf with a goat without a man, then the wolf will eat the goat. If you leave the goat with the cabbage, the goat will eat the cabbage. In the presence of a man, a goat cannot eat a cabbage, and a wolf cannot eat a goat.

Did the peasant ask the brothers for advice on how to transport his cargo across the river?

The brothers helped the peasant, and then Fedor caught up with them. And they went together to Koshchey the Immortal.



Problem 2. To put up the fence, 20 pillars were dug in a row 2 meters apart. How long will the fence be?

Problem 3. How to fill the barrel exactly half, but without using anything for measurement?

Tasks of Koshchei the Immortal:

Problem 1. The miller came to the mill. In each of the four corners, he saw three sacks of flour. There were three cats on each bag, and each cat had three kittens with her. The question is, were there many feet in the mill?


The brothers took half a barrel of living water, went to the garden where an apple tree with rejuvenating apples grew. They approached the apple tree and saw that a snail was trying to climb to its top.

Every day the snail climbed 3 inches up, and every night it slipped 2 inches down. Up to the top of the apple tree 12 vershoks. How long does it take to get to the top?

Having collected living water and rejuvenating apples, the brothers went home. They safely reached their kingdom-state. They brought to my father what he asked for. And since then the king has not been sick, and everyone lived happily ever after.

Slide 2

Once upon a time there was a king. The tsar had three sons: Fedor, Yegor and Ivan. The king had riches - not to count. Yes, he began to get sick. So he sends his sons for living water and rejuvenating apples. The sons set out.

Slide 3

The sons drove for a long time, and they met a passer-by. "Is it far to the village?" You have traveled a third of the entire distance, and if you still drive 2 miles, you will be exactly in the middle - a passerby answered. How many miles still need to be covered by the sons? Solution: 2 versts is 1/2 - 1/3 \u003d 1/6 of the total distance between villages, which means that the entire distance is 1 i.e. 6/6 is equal to 2۰6 \u003d 12 (versts). 1 / 3–4 versts, and 12-4 \u003d 8 (versts) remain. Answer: 8 versts

Slide 4

The sons drove to the village and went to the inn to rest. We ordered the hostess to cook potatoes, but they themselves fell asleep. The hostess cooked it, put it on the table and left. Fedor woke up, ate the third part and fell asleep again. Then Yegor woke up, counted the potatoes, ate the third part and also fell asleep. Ivan woke up and ate a third of the remaining potatoes. Then all the brothers woke up and saw that there were 8 potatoes left in the cup. How many pieces did the hostess cook and how much more should each of the brothers eat so that everyone gets the same amount?

Slide 5

Solution: Ivan left 8 potatoes for the brothers, i.e. 4 each, so he ate 4. It turns out that Yegor left 12 for the brothers, 6 for each and ate 6 himself. It follows that Fyodor left 18 potatoes to the brothers, 9 for each, and ate 9 of them himself. So, the hostess served 27 potatoes on the table. The answer is 27 potatoes

Slide 6

The brothers wandered for a long time until they reached the hut of Baba Yaga. They told where and why they were going. “Guess my riddles, then I'll tell you where to find living water and rejuvenating apples,” said Baba Yaga

Slide 7

Answer: 1) 3 2) the same 3) 100 Ducks flew: one in front and two behind, one behind and two in front, one between two and three in a row. How many ducks flew? Which is heavier: a pound of iron or a pound of fluff? Divide a half in half

Slide 8

The brothers guessed all the riddles and Baba Yaga showed them the way to her middle sister, and left Fyodor so that he could cut wood for her. Sawing off one piece takes 1 minute. In how many minutes will he cut a five meter long log? Answer: 4 minutes

Slide 9

Meanwhile, Egor and Ivan reached the dense forest. In that forest there is a hut on chicken legs. The middle sister of Baba Yaga lived in that hut. She had 20 girls in her service

Slide 10

In the evenings, she went around the house and checked if everything was in order? There were 7 girls on each side of the room. 3 3 2 2 3 2 3 2

Slide 11

But one day 4 girlfriends came to the girls and stayed with them to spend the night. There were 24 of them. They were placed so that on each side there were again 7 girls. How did the 24 girls fit if there were 7 girls on each side? 24 girls were placed like this: 1 1 1 1 5 5 5 5

Slide 12

The next day 4 girlfriends left, 4 more girls went to see them off. There are 16 girls left. And they were positioned so that on each side there were again 7 girls. How did the 16 girls fit if there were 7 girls on each side? Here's how they fit: 3 3 3 3 1 1 1 1

Slide 13

The middle sister of Baba Yaga found out what the brothers were going for, and decided to help them. She sent them to her younger sister. They drove, drove, saw - the hut was standing on chicken legs, turning. And in the hut younger sister Baba Yagi.

Slide 14

She has a cow, a goat and a sheep. The younger sister is sitting, wondering how to feed her animals? A cow eats a cart of hay in a month, a goat in 3 months, a sheep in 6 months. How many days will a hayload of these animals last?

Slide 15

Solution: If there are 30 days in a month, then in 1 day the cow eats 1/30 of the hay load, the goat - 1/90 of the cart, and the sheep - 1/180 of the cart. Together they eat 1/30 + 1/90 + 1/180 hay in 1 day. 1/30 + 1/90 + 1/180 \u003d 1/20 This means that in 20 days they will eat 20/20 carts, i.e. 1 or all of the hay. And for a month you need 30/20, that is, 1.5 wagons. Answer: for 20 days.

Slide 16

The brothers helped Baba Yaga's sister, dung hay for her animals, and she told them how to get to Kashchey the Immortal, who had living water and rejuvenating apples. Here they went again along the road. Ahead is the river. They see a peasant sitting on the bank of the river, who needs to transport a wolf, a goat and a cabbage.

Slide 17

Only one person can fit in the boat, and he is either a wolf, or a goat, or a cabbage. If you leave a wolf with a goat without a man, then the wolf will eat the goat. If you leave the goat with the cabbage, the goat will eat the cabbage. In the presence of a man, a goat cannot eat cabbage, and a wolf cannot eat a goat. Did the peasant ask the brothers for advice on how to transport his cargo across the river?

Slide 18

Solution: First, the peasant needs to transport the goat to the other side, leaving the wolf with cabbage, then return, take the wolf, transport him to the other side, and take the goat back with him. Leaving the goat on the shore, you need to transport the cabbage to the wolf, then transport the goat.

Slide 19

The brothers helped the peasant, and then Fedor caught up with them. And they went together to Kashchei the Immortal. But it is not easy to cope with Kashchei. He does not want to give away living water and rejuvenating apples. He began to set tasks. Tasks of Kashchei Bessmertny: Task 1. The miller came to the mill. In each of the four corners, he saw three sacks of flour. There were three cats on each bag, and each cat had three kittens with her. The question is, were there many feet in the mill?

Mathematical tales

Performed:

student of grade 3-A

Lisyak Anastasia


Objective of the project:

Find out what role numbers play in our life.

Once an unpleasant story happened to the numbers.

So what happened?

We learn about this from a fairy tale.


"Important figures"

There were numbers in the mathematical kingdom

0 to 9. Digits as digits.


Some of them

were thin

such as, and Some are full, rounded.

These included

Some of the numbers were with a tail,

such as,

and Someone with a circle like


In general, they were different, unlike each other.

Despite this, the numbers were very close.

between themselves


But one day, at a holiday, the letters told the numbers that they are more important. Without letters and words, no one would understand anything. And the numbers were offended and scattered in all directions. And such chaos began!


Letter AND , for example, stands on 1 place in the alphabet,

letter D - on 5 and the letter I - on 33 location.

And now, when there are no numbers, it is not clear where

get them up.

Such a confusion!

- ? - ? - ? - ?

In the mathematical realm, no one could really count anything, and panic began.


Then the letters apologized to the numbers, and asked them to continue to fulfill their digital duties.

And everything fell into place.
