Mathematical problems for ingenuity for grades 1 and 2

This is an educational article on mathematics, before starting classes we recommend that you read the introductory part

This activity does not require any skill, knowledge or ability to perform complex calculations. All you need is a child's ingenuity and imagination. This section contains folklore mentality problems that have been passed down orally by many generations of mathematicians.

In addition, the task includes fairly well-known logic problems and puzzles from the literature of past centuries. For ease of perception, some of them have been reformulated in a language that is more understandable for today’s schoolchildren.

Please note that some problems are comic and to solve them you just need to carefully read the conditions.

Each problem is given with a solution, based on it, you can help the little student, give him an idea, give him a little hint, but in any case you should try not to tell the solution to the problem in full.

Remember: the main thing is that the child solves at least one or two problems on his own. The fact that you tell him how to solve this or that problem will be much less useful than if you solve it yourself.

We also advise you not to rush; if you cannot solve a problem, you can postpone solving it for a couple of days and move on to the next task.

Hints are given for some problems - you can use them to help your child solve the problem without telling the whole solution.

Task No. 1

Dasha and Masha went to the cinema, along the way they found 2 rubles. How much money would the girls have found if they had also taken Olya with them?

Clue

Where did the money come from on the road? How much money would be there if Masha went alone?

Solution

This is a joke task. The amount of money does not depend on how many people find it.

Answer:

2 rubles.

Task No. 2

Nikita came out from the village of Myshki to the village of Koshki, and Ira rode out on a bicycle to meet him, from the village of Koshki to the village of Myshki. Which of the children was closer to the village of Cats when they met?

Clue

What happens when someone dates someone? How far are they from each other?

Solution

When a meeting occurs (no matter who with whom), those who met are in the same place. This means that Ira and Nikita were at the same distance from everything, including the village of Koshka.

Answer:

the same.

Task No. 3

Imagine that you have 5 sticks. How many sticks will there be if you break two of them into halves?

Clue

Is half a stick also a stick?

Solution

If we break one stick, then instead of one we get two sticks. This means that if we break two sticks, then instead of two we will have four, that is, two more sticks will be added. Since we did not touch three sticks, there will be seven sticks in total.

Answer:

seven sticks.

Task No. 4

Sveta can cut any ribbon in half in 1 minute. She really wants to cut her red ribbon into 6 pieces. How many minutes will Sveta be able to cope with this?

Clue

How does the number of pieces increase after one cut?

Solution

Note that in one minute Sveta increases the number of pieces of ribbon by 1: After 1 minute: 2 parts. (1 + 1 = 2). After 2 minutes: 3 parts. (2 + 1 = 3). After 3 minutes: 4 parts. (3 + 1 = 4). After 4 minutes: 5 parts. (4 + 1 = 5).

After 5 minutes: 6 parts. (5 + 1 = 6). This means that in order to get 6 parts from one part of Sveta, she will need = 5 minutes.

We can assume that the number of cuts is always 1 less than the number of parts: 6 – 1 = 5 cuts need to be made, which will take 5 minutes.

Answer:

5 minutes.

Problem #5

There were four glasses of jelly on the table. Misha drank one glass of jelly and put the glass back in its place. How many glasses are there on the table now?

Clue

Where did the jelly glass go?

Solution

Since the empty glass was put back on the table, the four glasses were still standing on the table. The fact that now there are three full and one empty does not matter. The main thing is that there are four of them.

Answer:

4 glasses.

Problem #6

In one family, each of two sisters has three brothers. How many children are there in the family?

Clue

If a sister has three brothers, how many boys are there in the family? Can two sisters have different numbers of brothers?

Solution

According to the condition, each sister has three brothers. This means that there are three boys in the family. And two girls, since it is given that there are two sisters. That is, a total of 3 + 2 = 5 children.

Answer:

5 children: three boys and two girls.

Problem No. 7

4 boys went to the store: Dima, Kolya, Nikita and Andrey, on the way to the store they found 4 rubles. How much money would Nikita find if he went to the store alone?

Clue

And if 25 boys went to the cinema, how much money would they find?

Solution

The amount of money lying on the road cannot depend on the number of children who went to the cinema. From this we conclude that Nikita would have found the same 4 rubles if he had gone to the cinema alone.

Answer:

4 rubles.

Problem No. 8

Marya was going to Moscow, she met 3 men, each man had 3 bags, each bag had 2 cats. How many creatures were heading to Moscow?

Clue

Where were the men going?

Solution

Men with cats in bags walked towards Marya, and Marya was heading to Moscow. This means that the men with the cats were walking in the opposite direction from Moscow. Consequently, only Marya went to Moscow.

Answer:

1 person – Marya herself.

Problem No. 9

One corner of the lid of the quadrangular table was sawed off. How many angles does the lid have?

Clue

Draw a table top on paper and try to “saw off” the corners using a ruler. What will happen?

Solution

Let’s draw a “table cover” on paper in the form of a square and “saw off” the corner (see figure). In the picture, the “sawed off corner” is dark. What remains is a white polygon. It has five corners.

A comment

Perhaps your child will go further and think about what will happen if the corner is sawed off not as in the picture - “a little bit”, but more. Then the lid may still have four corners (if the cut line goes through the corner - see Fig.

Poems about the number 2 for 1st grade

***

But this is number two. Admire how it looks: The deuce arches its neck, Its tail drags behind it.

***

By the river in a gray forest, the TWO cried to the beaver: “I don’t dare go into the water, I don’t know how to swim!” TWO minnows whisper to her: “You’re sad, girlfriend, in vain!” TWO dragonflies flew in: - Wipe away your tears, TWO! TWO little foxes came running and consoled the TWO little foxes: “You look like a swan, so you can swim too!” THE TWO sighed joyfully, shook its long neck, went into the warm water and swam like a swan!

***

Only an equal one is suitable as a pair for our unit. For example, patent leather boots, the same size. Although not on one leg, This pair is boots! They also consider a cup and saucer, Mom and Dad, to be a couple.

***

Number 2 is still strange: it looks like a swan. Proud, majestic, she walks everywhere like a peahen. He is very friendly with the little one, with his own sister. Divides it into two parts evenly and behaves so modestly. It’s a pity when a D is punished for knowledge.

***

Neck, tail and head, Like a swan number 2.

***

And the Cat has two ears. The ear is the organ of hearing. With its ear the Cat hears the scratching of mice.

***

And this is the number two: There is both a tail and a head With a long swan neck, The neck goes into the back.

***

I probably won’t be able to bend my neck like a deuce. Maybe you can? Barely! A swan with the number 2 can do it.

***

Her appearance is like a comma, her tail is crooked, and it’s no secret: She loves all lazy people, but her lazy people don’t.

***

Two sisters - two hands Chopping, building, digging, Pulling weeds in the garden bed and washing each other. Two hands knead the dough - left and right, rake in the water of the sea and rivers while swimming.

***

We are given one head, And two eyes and two ears, And two temples, and two cheeks, And two legs, and two hands. But there is one nose and mouth. But if we had the opposite, One leg, one arm, But two mouths, two tongues, - We would only know what we ate and chatted!

***

Who does the deuce look like? Maybe for a duck? Wait! No, only a swan, arching its neck, can compare with her.

***
