Unit 1 how to draw a mathematical tabloid in the second volume of fourth grade mathematics
The drawing of the first unit of the fourth grade mathematics volume II is as follows:

1, take out the prepared A4 paper, marker and Gou Xianbi.

2. First, determine the approximate position of the handwritten newspaper to be drawn on A4 paper.

3. Write all the frame parts of the newspaper with Gou Xianbi's handwriting on A4 paper.

4. Draw some erasers, triangles, compasses and three-dimensional graphics around the border.

5. Then, write the headline "Fourth Grade Math Newspaper" at the top of the handwritten newspaper.

6. Write the frame of the newspaper by hand with beautiful blue paint.

7. Then resign and paint all the decorations around the frame with beautiful colors.

Archimedes, an ancient Greek scholar, died at the hands of Roman enemy soldiers who attacked Sicily. ), people carved the figure of the ball in the cylinder on his tombstone to commemorate his discovery that the volume and surface area of the ball are two-thirds of that of the circumscribed cylinder.

Archimedes was born in Syracuse, Sicily, at the southern tip of the Italian peninsula in 287 BC. Father is a mathematician and astronomer. Archimedes had a good family upbringing since childhood. 1 1 years old, was sent to study in Alexandria, the cultural center of Greece.

In this famous city known as the "Capital of Wisdom", Archimedes Job collected books and learned a lot of knowledge, and became a protege of Euclid students erato Sese and Cannon, studying geometric elements.

Ju Lushi, born in 624 BC, 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.
