Peculiarities of perception of comic riddles by older preschoolers

From 5 to 7 years old, children are already good at telling jokes and understanding the jokes of others. Children of this age will be able to answer such a comic riddle correctly, provided that they understand it. If the sense of humor is poorly developed, then the child will solve the problem using simple calculations. And the answer will be wrong. The answers to such riddles must be explained to the whole group using visual methods.

Such problems are suitable as a warm-up before math classes. This contributes to the good development of mental operations. The proposed mathematical riddles with answers can also be used during the lesson in order to clarify the concept of any number.

You can also use humorous riddles when transitioning from one activity to another to give the children a little distraction and relaxation.

Mathematical riddles for logic

This is a very useful gymnastics for the mind. Logical mathematical riddles are quite complex - you will have to think a lot about the answers to them. Here are some of them:

  1. Misha had a large but sour orange. And Vitya ate big, but sweet. What is similar about oranges and what makes them different from each other? They are similar in that they are both large, but the difference is that one turned out to be tasty, and the second sour.
  2. Friends Vera and Nastya looked at the illustrations. One of them had a book in her hands, and the second had a magazine. Where did Nastya look at the pictures if Vera was not holding a magazine in her hands? Of course, in a magazine.
  3. Vasya and Petya decided to draw. Car and tractor. What was in Vasya’s picture if Petya didn’t want to draw a tractor? Of course, Vasya drew a car.
  4. Kristina, Vitya and Slava lived in multi-storey houses. Two of them were three-story, one was two-story. Kristina and Slavik did not live in the same houses, nor did Slava and Vitya. Who lived in which house? This problem is more complicated. The correct answer would be: Slava lived in a two-story house, and Christina and Vitya lived in a three-story house.
  5. Zhenya, Misha and Andrey loved to read books. One was interested in cars, another - stories about war, the third - about sports. Who read what if Zhenya didn’t read about war and sports, and Misha didn’t read about sports? Complex but has a fairly simple answer. Since Zhenya did not touch books about war and sports, it means that he read about travel. Misha didn’t read a book about sports, which means he chose a book about war. There is no information about Andrey, but by process of elimination we decide that he gets a book about cars. It's simple.
  6. Vera, Masha and Olesya loved to embroider. One is hearts, the other is houses, the third is patterns. Who embroidered what if Vera didn’t embroider hearts and houses, and Masha didn’t like hearts? Also quite a difficult task. Vera embroidered patterns, Masha embroidered houses, Olesya embroidered hearts.

Square

Don't delay your answer -
Next to Y and Z.
X

Sometimes it's sharp, sometimes it's dull,
But most often it is direct.
Blunt and sharp have different sizes,
Direct - constancy is an example.
The degree is changed between acute and obtuse,
Only a straight line remains straight.
Corner

To receive the amount,
Need two numbers...
Fold

All four sides
Such figures are equal.
And the angles are right
Who are we?
Squares

The peak serves as my head.
And what you consider to be legs,
All are called parties.

Looks in the mirror for a long time.
Can't get enough of it

She only has three in total.
Three sides and three corners.
A schoolboy can't go wrong
And he will say that the figure is that
It's called...
Triangle

Guess without delay:
Always requires a solution.
There is a question, a condition,
And without contradiction.
Task

We add numbers with a plus
And then we calculate the answer.
If “plus”, then, without a doubt,
This action is...
Addition

If it’s more than five times,
We will have numbers...
Multiply

Take me quickly
And draw a circle.
If necessary, open it
Measure the distance.
Compass

It is not out of malice that he takes away,
He's just doing his duty.
Take away a big master
This is a familiar sign to everyone.
Minus

It is sharp, but not the nose.
There is a direct, but not a question.
And there is a blunt one, but not a knife.
What could this be?
