What knowledge should a four-and-a-half-year-old baby master? I believe that every parent attaches great importance to children's knowledge enlightenment. Early education, family teaching, picture books, etc. Will arrange for the children. Children learn something at every age. Four and a half years old is the age to go to kindergarten, so what knowledge should a four and a half-year-old baby master? Let's see:

Four-and-a-half-year-olds should master some basic knowledge:

1, color discrimination

Let's talk about three primary colors: red, yellow and blue.

Teaching in kind is easy to understand. At the same time, red apples, red strawberries, red pens and red colored paper are displayed. Say something like "red apples" and "red strawberries" to children. Then, if the child understands the three primary colors, he will gradually increase the number of colors, such as white, black, green, pink, orange, purple, brown and so on.

The more children's color vision is cultivated from an early age, the more superb ability to distinguish subtle color differences can be cultivated. So, don't be limited to ten colors, even if children can recognize 50 colors and 100 colors, it is really beneficial.

In order to cultivate excellent sense of color, the most important thing is to take children out and let them feel and linger in the colors of natural scenery. Red sunrise, blue sky, white clouds, green trees, yellow flowers ... the most indispensable thing in nature is color.

At the same time, as early as possible, cards such as famous paintings will be made for children every day. Children can naturally understand the nuances of the painter's use of color.

Let the children name the colors they create. Let him challenge and see how many different colors he can create. Use these created colors to describe things like strawberries and beans, and cultivate his interest in painting.

Step 2 recognize shapes

Let children notice that there are many shapes in daily life. In this way, children will show interest in shapes. Round sun and moon, square windows and books, triangular trees and triangular mountains. I began to teach children these things when I was over one year old.

If the child understands circles, triangles and squares, let him notice that there are many other shapes, such as oval, rectangle, star, cross, diamond and trapezoid. If you can draw circles, triangles and squares with a pencil, you can write or draw good pictures. Shape is basic. If children are allowed to play the game of building a house with various shapes of building blocks, they can grasp the feeling of shape three-dimensionally. Start by creating things. Building block games and mud games can cultivate things that children like to create.

Various shapes can be used to create various designs. Remember, children who create fun, once they have leisure time, will try to create things of various shapes. Perhaps it is from this time that they cultivate the soil to become future designers.

The result of playing this meticulous and accurate assembly game is to cultivate accurate computing ability, concentration ability, thinking ability and creativity. It can also cultivate the flexibility of shooting.

Step 3 identify the size

The difference between "big and small" is a very easy concept for children to understand. The father is big and the children are small; Elephants are big, ants are small, and so on. You can know the size of the textbook and give many examples in life.

At what age can children understand the difference between big and small? It started when I was about two and a half years old. Know the size of the circle and the size of the snack. If children are allowed to see big snacks and small snacks and choose from them, they will definitely choose the big one.

Step 4 know the numbers

In order to cultivate children who are sensitive to numbers, it is very important to make them aware of the numbers in their lives and get close to them as soon as possible. When eating, let the children notice the father's bowl, the mother's bowl and the child's bowl. There are three bowls in one bowl. There are two chopsticks.

When taking a bath, show him two eyes, a nose, a mouth, two ears and five fingers ... even such body parts make him notice the numbers. When going out, let him pay attention to how many stairs there are and how many bicycles are parked there ... If he keeps focusing on numbers like this, he will cultivate children who are very sensitive to numbers.

Four-and-a-half-year-olds should master the following knowledge:

1, spatial cognition

The concept of "up and down, back and forth, left and right, inside and outside, far and near, etc." is called spatial cognition. Please teach children through specific examples such as the up and down of the table, the left and right of the child's hand, the inside and outside of the box, and the distance the ball is thrown. It will be easier for him to understand.

If you can't tell the right from the left, "When eating, the hand holding chopsticks is right (left)" or "When shaking hands, the hand is right" and so on, these are also specially taught to children. This is good, too.

Step 2 compare

"greater than …, less than …," greater than …, less than … "These are all comparisons.

To teach children "to compare two things is to compare." Take out two pencils. "This pencil is longer than this one." Teach children which is long and which is short like this.

It is a very good practice to teach children as many antonyms as possible when teaching children to compare. Hot and cold, fast and slow, sweet and bitter, etc. Because antonyms are words with opposite meanings when compared.

Step 3 order

Besides the first, the second, the third and the last one at the beginning, there is also the order when you see the coordinates, such as the second from the left, the third from the right, the fourth floor from top to bottom, the bottom, and the fifth from the right on the top floor.

There is also the order of size, such as "the third largest" and "the second longest". Let children understand all these sequences.

4. Money

Three or four years old is an important period to learn the concept of "money". Let children master the concept of money through The Imitation Game, such as "playing the game of shopkeeper".

In addition, when shopping in the supermarket, when buying car and tram tickets, etc. In order not to cause trouble to others, please let your children touch money in real life experience.

Five dollars for Zhang Yiyuan, ten dollars for Zhang Yiyuan, two tens for fives, fifty dollars for five tens, ten hundred dollars for ten, and so on. Children can be taught to play games of "pretending to be a bank" and "pretending to be a shopkeeper" with toy coins.

After school, a four-and-a-half-year-old child who has no such experience can't have abstract imagination and can't understand the questions he asks when he encounters a word arithmetic problem about money.
