What do the fourth-grade math tabloids write? Unit 4?

What does the fourth-grade math tabloid write? The content of Unit 4 is as follows:

1. Numbers and calculation: introduce the types of numbers (integers, decimals and fractions), basic mathematical operations (addition, subtraction, multiplication and division) and their applications in daily life.

2. Graphics and Geometry: Introduce basic graphics (lines, angles, triangles, quadrangles, etc.). ), and their basic properties and classification. At the same time, the calculation methods of perimeter, area and volume of some geometric figures can be discussed.

3. Statistics and probability: introduce the basic concepts and making methods of statistical charts, as well as the basic concepts and calculating methods of probability. You can illustrate some simple statistical and probability problems, such as weather forecast and coin toss.

4. Mathematical thinking: Introduce some mathematical thinking methods, such as induction, deduction and analogy. Examples can be given to illustrate the application of these methods in solving mathematical problems.

5. Mathematical stories: Introduce some interesting mathematical stories, such as mathematicians' interesting stories and the interesting application of mathematics in life.

6. Mathematical Games: Introduce some interesting mathematical games, such as Sudoku and Huarong Road, and their roles in training mathematical thinking and problem-solving ability.

7. Math puzzles: Introduce some math puzzles, such as puzzles and riddles, and their functions in stimulating math interest and cultivating thinking ability.

First, expand the information.

Mathematics tabloid refers to interesting tabloids related to mathematics. The main contents are: mathematical knowledge, mathematicians' stories, interesting mathematical problems, mathematicians' famous sayings, etc. You can use handwritten newspapers, computer printing, newspaper clippings, Olympic math questions and other forms.

Mathematics tabloid is demanding and difficult, so students had better finish it with their parents. But it can't be a single form. We should apply what we have learned and not blindly and rigidly imitate old-fashioned forms.

Second, mathematical stories.

Born in 624 BC, Ju Lushi was the first famous mathematician in ancient Greece. He used to be a shrewd businessman. After he accumulated considerable wealth by selling olive oil, Cyrus devoted himself to scientific research and travel.

He is diligent and studious, at the same time, he is not superstitious about the ancients, and he is brave in exploration, creation and positive thinking. His hometown is not too far from Egypt, so he often travels to Egypt. There, Ju Lushi learned about the rich mathematical knowledge accumulated by ancient Egyptians for thousands of years. When he traveled in Egypt, he calculated the height of the pyramids in a clever way, which made the ancient Egyptian king Amerasis admire him very much.
