After reading DK Children's Mathematical Thinking Manual 1 This summer vacation, I read an interesting book called DK Children's Mathematical Thinking Manual, written by Mike from Britain. Goldsmith's works, Cyber, England. Bennett Cartography, a hardcover book published by Popular Science Press.
The cover is in the shape of a brain, which is filled with all kinds of numbers and symbols and tools related to mathematics. The content inside is very rich, including knowledge explanation diagram, scene diagram, specific section diagram, hand drawing and other pictures, with text explanation. I like missing numbers best. It tells the story of Sudoku, Kakuro and the number circle. Sudoku is performed in a 9×9 square, which consists of nine 3×3 sub-squares. The number 1-9 can only appear once in each sub-grid, column and row. You need to use the given numbers in the grid to fill the empty grids one by one through calculation. Every time you fill in a number, more clues will appear to solve the problem.
It turns out that mathematics is not just memorizing formulas and doing exercises. As long as you read this book carefully and patiently, you will see interesting stories behind math experiments and knowledge.
DK Children's Mathematical Thinking Manual 2 This summer, I read the book DK Children's Mathematical Thinking Manual recommended by my teacher. This book is about mathematics and talks about many interesting mathematical problems. Also won the "China Excellent Popular Science Book Award". Although I still can't understand some of the contents in the book, I still appreciate the charm of the mathematical world.
What impressed me most in this book is Pascal Triangle. Pascal Triangle was invented by Blaise Pascal, a scientist, mathematician and inventor. Pascal's triangle contains many magical mathematical laws, including triangle number, square number, power number, and many types of sequence. Pascal triangle can also be used to learn probability, which is the possibility of something happening and is very practical in life. The invention of computer is also related to Pascal, so Pascal's triangle is really a very powerful mathematical knowledge.
I like this book very much, because by reading this book, my mathematical thinking can be well exercised and I can become smarter.
