Almost every day, parents tell me that their children are active-

Every time I let my children read a book or write a word, they always look around in less than ten minutes. Sometimes I think he has studied, but at first glance he just scribbles on paper. Why can't my children be quiet! Do you have ADHD?

In fact, being lively and active is a child's nature. Preschool children tend to think in images, so it is difficult to stay focused when faced with abstract characters in books.

Parents should be "sparse" rather than "blocked", and make use of the active characteristics of preschool children to carry out appropriate early mathematics education instead of training children's thinking more efficiently.

Graffiti can exercise spatial cognition, so stop criticizing children for desertion!

According to the requirements of the Guide to Learning and Development for Children Aged 3-6, it is a mathematical ability that preschool children must master to perceive the relationship between shape and space. The specific requirement is to creatively assemble shapes with common geometric figures.

And children are free to "scribble" on white paper, which happens to be a rare opportunity for spatial thinking-

Isn't it in line with the requirements of the guide to doodle various geometric figures and then combine and split them?

Next, I will teach parents a simple and easy-to-learn early education method, and teach children to learn mathematical knowledge related to spatial graphics in graffiti.

Simple and naive painting of stars hides so much mathematical knowledge!

(1) interval connection point method

For adults, drawing a simple five-pointed star is a subconscious "instinctive reaction", but for preschool children, the first step is to teach them the steps of drawing stars.

The most intuitive method is "connecting points". For example, to draw a five-pointed star, first draw five points on white paper, randomly choose a starting point, and connect a line every other point to draw a five-pointed star.

After children learn to draw a five-pointed star, they can increase the number of points to seven or nine, so that children can still remain highly sensitive to images and space in more points and lines.

(2) Graphic mosaic method

The connected point method introduced earlier is suitable for odd-numbered stars, and even-numbered stars are suitable for drawing by means of graphic splicing; For example, a six-pointed star can be seen as two triangles.

Similarly, an octagonal star can also be formed by splicing two quadrangles. After drawing specific figures, parents can also sum up the rules of drawing stars with their children.

Two identical polygons can be combined into a star, and the number of angles combined into a star is twice the number of sides of the polygon.

This rule applies to stars with ten or more angles.

(3) Thinking: Why is the five-pointed star the most common?

In addition to graffiti, drawing stars can also extend many early childhood education problems that exercise mathematical thinking;

For example, parents can let their children think about why the five-pointed star is the most common in life.

After just finishing the process of drawing stars, children will feel that among the stars with more than five corners, the five-pointed star needs the least strokes and the least effort, and is definitely the first choice for drawing stars;

However, when the angle of the star is less than 4, it is impossible to draw the star quickly, whether through the connection of points or the splicing of figures, and other forms of stars can only be drawn by more complicated methods.

This method introduced today can make graffiti painting stars an early education process for children to learn preschool mathematics. Parents may wish to try it with their children with a pen and paper ~

Welcome to pay attention to He Qiu Guang's pre-school math, privately believe the key words of "course" and play math with famous teachers.
