Put the even numbers in order. How to learn to identify even and odd numbers? Even and odd numbers
Sequential account.
When the baby learns the names of numbers well, play with him in turn counting: you say 1, he says 2, you say 3, he says 4, etc. At first he will want to call your numbers; explain to him that this is prohibited by the rules of the game. Next time he should start: he says 1, you say 2, and so on. When the child can easily cope with such a task, involve someone else in the game (say, another child, he will like it too!) And play with three, then four, etc. Now that he quickly figured out what's what, continue to play only if he shows interest.
Even and odd numbers.
To explain this concept to a child, take two plates and a handful of beans:
This is your plate and this is mine. Here are two beans. Can you put as many beans on my plate as you have on yours? Oh sure! You can put one bean on your plate and one on mine. Now here are three beans for you, see if you can do the same with them? .. No! There are two beans in one plate, and one in the other. You see, it turns out that the number 2 can be divided into two equal parts (such a number is called even), but the number 3 cannot be divided into two equal parts (it is called odd). Now let's see how 4 behaves...
When the baby understands the difference between an even and an odd number, play with him in turn counting, while one of you will call odd numbers, and the second - even.
Numbers in their graphical form.
Before showing the child abstract symbols denoting numbers, it is necessary that he learns to count well. Otherwise, he will become like most of us (and this is undesirable!): for him, counting will mean only playing with abstract symbols. Imagine a person for whom the words "banana", "chair", "shoe" are associated exclusively with their written form, and not with specific objects. Such a person would really know nothing about the world around him, and his acquaintance with the language would be superficial and useless. How he reminds all those who freeze in horror at the word "mathematics". Such people know the symbols, but do not really understand why they are needed and what they symbolize!
As with the alphabet, there are children who are very fascinated by the process of naming an abstract symbol. They instantly learn the numbers, it is enough to show them several times. But there are other children who, being able to count well, cannot remember which number corresponds to which number. Because they don't care! Here is a game they should enjoy.
First, show your child a picture with the first three numbers. When he learns them, reward him by including a fourth character in the game. Still use only the interrogative form. Only in this case, he will call the number, and not you. When the child learns the numbers with small drawings, show him the same ones. figures, but without figures. Remind your child of the text if he forgets it. In this way, even the most stubborn child will quickly learn the numbers. BUT GO TO THE NUMBERS ONLY WHEN HE LEARNS TO CALL THE NUMBERS AND COUNT!

And in life, where is the knowledge of even and odd numbers used? First, any even number of something is divisible by half. Secondly, this is important information if you need to find any address. If you go from the beginning of the street, then the houses with even numbers will be on the right, and with odd numbers on the left. Even in trains, the numbers of berths are: the lower ones are “odd”, and the upper ones are “even”. The schedule of appointments with doctors or working days with other specialists can be on even days or on odd days. There are also road sign with a parking ban or permit: on even or odd days of the month.
Count by even twos up to a hundred! This skill will be useful for the guys in studying the multiplication table for 2, 4.

Mathematical fairy tale
Once upon a time, an amazing story happened in the kingdom of Mathematics. The numbers that lived in this kingdom were very friendly. They often went to visit each other, got together and came up with various games. Once they decided to play such a game: each number had to be divided by 2. But in the end, all the numbers quarreled and even began to live on different sides of the streets.
– What do you think happened? (Not all numbers are divisible by 2)
- That's right, since then, those numbers that could be divided by 2 began to live on one side of the street, and those that could not be divided by 2 began to live on the other side.
Let's try to spread our numbers together.
(On the blackboard at home, children carry cards with numbers through the streets.)
2, 4, 6, 8, 10
1, 3, 5, 7, 9
- The street where the numbers 2, 4, 6, 8, 10 live, which could be divided into 2, began to be called - EVEN, and the numbers - even.
- The street where the numbers 1, 3, 5, 7, 9 live, which could not be divided by 2, began to be called - ODD, and the numbers - odd.
- And in our time, for convenience, the numbering of houses is arranged in a certain order: even numbers are on one side of the street, and odd numbers are on the other.

The game "Even or Odd?"
There are several buttons in my fist. Guess if it's even or not?
(If the player guessed correctly, the host gives him the buttons from his fist. If he didn’t guess, he changes the number of buttons and again turns to one of the spectators. In this way, the host recruits several players.)
Each player is given 5 more buttons. The player takes and clamps a few buttons in his fist, pulls it out in the direction of the other player and asks: "Even or odd?" The other player answers, if he guessed right, he takes it for himself, if he didn’t guess right, he gives his own, as much as was held in the hand of the first player. We play until one of the guys has accumulated 10 buttons.
Finger game "Even-Odd" rock, paper, scissors. Children in a pair of chorus count "one, two, three!" and show an arbitrary number of fingers on both hands. One of them is "even" and always shows only an even number of fingers (including a fist-zero). The other is "odd". Children count the sum of fingers and mark the sum on a sheet of paper in the column even or odd. The winner is the one in whose column there are more marks-sums.
Games that can be printed and played, replacing English words with Russian "even and odd":
"Ghosts"
houses of numbers for the composition of the number are specially marked differently: with a cloud - even, with the sun - odd 
Age - from 4 years old.
Materials: cards with numbers from 1 to 9 and additional numbers 1 and 0 for the number 10, red circles with a diameter of about 2 centimeters - 55 pieces.
How to make - I did everything on cardboard. For circles, you can use a wide lid from cream, toothpaste, or something like that as a template. If instead of circles cut into squares, the essence of this will not change. Alternatively, you can do it on a computer, then print it on thick paper. Immediately prepare an envelope or box for this material so that you do not get confused.
1. Call the child and offer him something to show. Sit next to a table or on a rug and start laying out numbers in a row with him: 1,2,3 ... Leave free space between the numbers. The child can finish this on their own.
2. Next, show in what order the circles should be laid out under the numbers (see photo, order is important). Under each digit, the number of circles corresponding to this digit is displayed. After the number 3-5, the child does it on his own. If he suddenly puts the last unpaired circle on the side in odd numbers, move the circle to the middle and pronounce the number, thus emphasizing the importance of this.
3. When all the circles are laid out, show the child that the number 2 has a path between the circles and you can run your finger there. At number 3, the finger gets stuck in front of an unpaired circle, at number 4, it passes, etc. At this stage, it is only necessary to comment on what is happening here, but not here. My daughter immediately dubbed the unpaired circle a dead end. After you have gone through all the numbers in this way, you explain that the numbers where the finger went are even, where the dead end is odd.
4. Then you can ask about individual numbers - even or not. Example: “Tell me, what is the number 4?”. When the child remembers this, explain that in other numbers, the last digit can determine whether the whole number is even or odd. For example, 3945 is odd, since there is an odd 5 at the end. In the future, you can play such a game - you call big number, and the child answers whether it is even or odd. A convenient exercise, since you can play it everywhere: on the way to the kindergarten, walking from the store, etc.
Pluses of the exercise: the child himself sees that even numbers are divided into two (the finger goes down, dividing the circles into two parts). This does not need to be explained, as the child understands all this clearly.
Note: I myself did not expect that my daughter would be able to understand the topic of even-odd numbers the first time!

During the classes
I. Organizational moment.
Guys, today we have a guest. I will now read to you about him, and you must guess him.
…He looks like a swimming swan. Bowing his head, he doesn't know what to do out of shame. (appears). A frequent guest in the notebooks of dirty, sluts. Many poems and stories are written about him. Nobody loves him, but his friend "five" everyone loves. (Number 2). Card display.
II. Communication of the topic and objectives of the lesson.
At the figure "two" have a secret
She is proud of it.
And we will reveal your secret
And we will tell all the children.
Today we need to reveal the secret of the number "two". Who will participate well in the figure lesson "two" prepared a gift.
III. A minute of cleansing.
Open notebooks. Write number.
Prescribe number. Which number will be written? (Three-digit number 232) .
IV. Verbal counting.
1. The old one was upset cat:
"I'm not lucky today:
A couple of mice hid in a hole,
Three hid headlong,
Under a heavy old wardrobe.
The couple scurried away in fright
In the box where the coal was stored,
Three - in the corner behind the panel,
And one of the cracks clogged up.
How many mice managed to hide from the cat?
2. How to arrange 7 chairs in a room so that there are 2 chairs on each wall?
Answer:
V. Work on a new theme.
1. Working with counting sticks.
Take 9 counting sticks and arrange them in pairs.
What does couples mean? (two each).
How many pairs did you get? (4 and one left). Good! Then take 10 sticks and put them in two.
How many pairs did you get? (5 pairs).
And now we work in rows. Each row gets numbers and arranges the sticks accordingly in pairs: 1 row - 7.8; 2 row - numbers 9,12; 3 row - number 10,5.
What did you get? Did you manage to split it into two? (Not really, in work with number 7 one stick was left without a pair. Also from 9 and 5).
That is, the ones you named numbers are not divisible by 2. Writing numbers to blackboard:
1 2 3 4 5 6 7 8 9 11 12
How are they located in numerical series? (5 is not divisible, but 6 is divisible, 7 is not divisible, but 8 is divisible, 9 is not divisible, but 10 is divisible, 11 is not divisible)
look numbers alternate. Let's complete number row on the right(record to be added). We have discovered the secret number two. It turns out that taken in circles numbers are called even.
What unites them? (These numbers are divisible by"two"). And the rest odd.
Can you split them into "two"? (Not).
Tell me, from what numbers the natural series begins? (from 1).
What is it number? (odd) . Numerical the series will continue.
How do you define it even numbers? (If a number is divisible by 2, then it even, and if it is not divisible by two - odd).
Well done!
2. And now let's put the rule into practice.
Write it down in your notebook numbers from 10 to 19, circle even numbers. (Student works at the blackboard).
name odd numbers(11, 13, 15, 17, 19) .
3. Find #3, p. 34. (Perform together, on the board).
What received numbers? (Even) .
What received numbers? (Even) .
Multiplying odd number, got even number. See what a secret he has numbers 2.
VI. Fizkultminutka.
Attention game. Show drawing.
We squat so many times
How many berries do we have.
How many circles do you see
We do so many jumps.
Bent over so many times
How many butterflies do we have.
VII. Work on the material covered.
Find problem number 4. Read. We decide on our own.
8m was cut off from a coil of wire, and 7m remained in it. How?
8 = 7 (m.)
15 - 8 = 7 Answer: 15m was in a skein.
We solve problem number 5. We only write down the answers in notebooks.
Multiplier 2 9 8 7 2 5
Multiplier 9 2 2 2 6 2
Product 18 18 16 14 12 10
(18, 18, 8, 2, 2, 2)
In response, what numbers received? (Even) .
a). Listen carefully to the logic problem.
There were 3 jackdaws and 2 crows sitting on a tree. Two birds have flown away. How many and what kind of birds could stay? (All possible answers: 1) 3 jackdaws; 2) 1 crow and 2 jackdaws; 3) 2 crows and one jackdaw).
b). Additionally.
Fill in the gaps with math symbols and numbers.
15*2+9=39 12+4*2=20
VIII. Summary of the lesson. and homework.
Today we discovered the secret of the number "two". What is the secret? ( Numbers that are divisible by 2 are called even, a numbers which are not divisible by 2 odd).
Number "two" prepared gifts for those students who actively participated in the lesson. Tell me yourself, who sat well and actively participated? (Laysan, Albert, Malik). We give these guys this picture.
Homework #6. You need to solve the examples.

Figures and numbers. There are a great many of them. For a little schoolboy, these are endless hooks, squiggles and circles. Just starting to master them, he learns that, it turns out, in addition to just numbers, there are also “even” and “odd”. What is it and how to remember everything? You can't do it without the help of mom and dad. Our article will give you helpful tips, as quickly as possible in the form of a game to explain to the child what is what.
How to easily and simply explain even and odd numbers to a child
So, what should be done by caring parents who want to teach their baby to distinguish one type of numbers from others:
When the child remembers well the sequence, the name of the numbers and their graphic expression, use this knowledge wherever you are. For example, you can call the house numbers out loud and ask if the number is even or odd. In the game, you can use price tags in stores, the number of dogs Aunt Klava has, the number of sweets that mom got for tea. Room for fantasy this case unlimited.
Explaining to a student concepts that are new and unknown to him is not an easy task. But it is important to be patient and make the learning process interesting so as not to discourage the child from the desire for knowledge.
