This essay is about the third grade of primary school. The title is "A Letter to Grandpa Li Yupei, the author of Math Detective 006". Everyone is welcome to contribute.

Dear Grandpa Li Yupei:

Hello!

As a primary school student who is about to enter the fifth grade, I have always liked all kinds of math popular science books you wrote. I have read your books on popular mathematics, such as Adventure of a Desert Island, Journey to the West of Mathematics, Mathematical Zoo, Story of Mathematical Intelligence and Mathematical Detective 006.

One of my favorite books is Math Detective 006. Today, I picked it up again and started my new round of wonderful math trip.

One of my favorite stories in this math book is Math Detective 006, which tells the story of how Monkey Detective 006 fought against the bad guys, regained the bamboo carving necklace and punished the bad guys. In this story, Monkey Detective 006 can always solve all kinds of thorny problems, save the day, and finally punish the bad guys, making them frightened, even the cunning fox lost to it.

After reading the book, I think: "The math detective 006 in the article is very smart and likes to use his head." We should all learn from the courage and wisdom of Math Detective 006! Compared with him, my knowledge of mathematics is too shallow. I really should learn more math! In ancient times, Wang Chong once said, "If you learn without knowing, you will know yourself, and if you walk past and present without asking, you will have nothing left. "Yes, I also want to study more and think more, otherwise, I won't know much knowledge.

Your other books are also wonderful! They all introduced me to a wonderful mathematical world, which made me understand a lot of mathematical knowledge from the book, such as: a truth and a lie together must be a lie; When doing complex math problems, you can try to use reasoning ...

Dear Grandpa Li Yupei, I have read so many interesting math books of yours, and my interest in math is getting stronger and stronger. To tell the truth, even our Olympic math teacher has been praising me: "flexible thinking, quick response, quick and good problem solving." I really appreciate your book. It is it that makes me interested in mathematics. In addition, I am also trying to integrate interesting math knowledge into my blog like you, and bloggers like it very much.

But there is still a big gap between my article and yours, and the style of writing is not as lively and interesting as yours; Mathematics knowledge is not as clear as you; Even the stories written are not as wonderful as yours. But these are exactly what I am trying to do. I want to say, "Dear Grandpa Li Yupei, the math story you wrote is like a lighthouse to me, which constantly inspires me to grow. I will always work hard to write a lively and interesting math story like you as soon as possible. "

Thank you, dear Grandpa Li Yupei, for creating so many interesting math stories for us. Here, I thank you on behalf of all the children!

hope

Grandpa Li Yupei is in good health!

Like your little reader: Jiuchong.
