What impressed me the most was this story: Ma Xiaotiao dreamed that he became a horse and raced with a kangaroo. There will be a trap every 123/8 meters from the runway to the starting point. Whoever falls into the trap will become the hunter's dish, and the winner will be awarded the title of "King of Forest Speed". Ma Xiaotiao runs 412 meters a second, and kangaroo runs 23/4 meters a second. After a while, the kangaroo fell into a trap. Ma Xiaotiao got carried away and fell into a trap. Ma Xiaotiao was puzzled: How did the kangaroo fall into the trap first? How far did he run when he fell in? I patted my head and suddenly came up with the answer: because (123/8)/(41/2) = 4/1,(123/8)/(23/4). So, the kangaroo jumped for 9 seconds when it fell into the trap. Ma Xiaotiao ran 1 1 sec when he fell into the trap. I took a look at the answer, ha! Well, I'm so happy!
Mathematics is like air, it surrounds us all the time, and we can't feel its existence all the time. As long as you study hard, master the method of solving problems, understand the meaning of the questions, clear your mind and calculate accurately. I believe that learning math well is not a very difficult thing, but full of fun. In fact, you will find that mathematics contains many interesting things!
Ma Xiaotiao plays math Part II: Ma Xiaotiao plays math. This summer vacation, I read a book called Playing Mathematics in Ma Xiaotiao. The book tells the story of Ma Xiaotiao applying mathematical knowledge to solve various mathematical problems in his life.
To tell the truth, I, a guy who doesn't know much about math, am really not interested in math storybooks. However, the book was attracted by the slogan, and I couldn't help opening it. I rummaged aimlessly, and gradually, I found that every story was so attractive, and there were so many ways to solve the problem that I felt very novel. The original boring numbers can also constitute an interesting topic! My interest in this book is also growing. At first, I always read the whole story at once to understand the method inside. Once, I decided to solve the problem in the story by myself. After careful consideration, I finally found the law and quickly worked out the answer. Haha, I succeeded! I excitedly told my father to share my joy, hoping to get his praise. Dad patted my little head and said encouragingly, "Great, I will definitely do it later!" " "Now I'm a little embarrassed, cuddling up in my father's arms like a coquetry. This book has made me understand the magical mystery of mathematics, and I strongly recommend it to you. In addition, I also want to say to you: "If you understand mathematics in another way, you will find it really interesting!"! " "
Ma Xiaotiao Plays Mathematics Part III: Comments on Ma Xiaotiao Plays Mathematics Part III: Comments on Ma Xiaotiao Plays Mathematics 1
Today, I saw Ma Xiaotiao's mysterious report card and original formula for playing mathematics. The main content of the mysterious report card is that the final exam of a semester is over and the report card will come out soon. Ma Xiaotiao just wanted to put away his report card, but Luhmann got wet. After returning home, Ma Xiaotiao asked the playful father and baby mother to guess their exam results. Ma Xiaotiao's father calculated on a piece of paper and said to Ma Xiaotiao, You did well in math, but it would be better if you did better in English and Chinese. From it, I learned that I should study hard in all subjects and not be partial to them.
After reading the original formula, the long-awaited summer vacation is coming, and everyone is busy doing homework while playing. In Ma Xiaotiao's family, students are advised to do their homework before playing. After doing homework for a while, Tang Fei suggested that everyone check their homework. In the process of checking homework, Tang Fei found that the careless angel's answer was different from others, and wrote the multiplier 78 as 87. Angel quickly wrote the correct answer.
I learned from it that you must check your homework carefully. Don't wait for classmates or parents to check your car. I will check my homework carefully in the future.
Reflections on Ma Xiaotiao's Playing Mathematics II.
Today, I read Ma Xiaotiao's questions about playing math and unclear time. Everyone goes to Ma Xiaotiao's house to play math games. Unconvinced, Lu Man wanted to kill Ma Xiaotiao, so he said to Ma Xiaotiao, I'll give you a question. I wonder if you can answer it? Ok, I accept the challenge, Ma Xiaotiao said confidently. Luhmann said: Today is Monday. /kloc-What day is 0/5? What day is it in 25 days? Ma Xiaotiao said to Luhmann: Start the class and I'll tell you after class. Ma Xiaotiao didn't listen to what the teacher was saying. He's just wondering what day it is. After class, Ma Xiaotiao said to Ruchman:/kloc-0.5 days later is Tuesday, and 25 days later is Friday. You're right, Ruman. Ma Xiaotiao turned away without looking.
Zhang Da was late for class, which made the teacher very angry. It turns out that Zhang Da miscalculated the time. Seeing the note left by Zhang Da's parents, Ma Xiaotiao helped Zhang Da figure out the exact time to get up.
It can be seen from these two stories that Ma Xiaotiao is a brainy child. When he encounters a problem, he will observe it carefully and find a solution.
Reflections on "Ma Xiaotiao Playing Mathematics" (Ⅲ)
Today, I saw Ma Xiaotiao's guess about how many pieces of wood there are in math. The story about how many logs there are tells that the wolf said to Ma Xiaotiao, "Hand over the fat sheep." . Ma Xiaotiao walked out of the room and said, No way. We will guess how many pieces of wood there are in a civilized way. If I'm wrong, the sheep is yours. If you are wrong, go home at once. The wolf guessed that there were 400 logs, and Ma Xiaotiao guessed that there were 430 logs. They counted out 430 pieces of wood. The wolf went home despondently, and the lamb was saved by Ma Xiaotiao.
In Tang Fei's conjecture, it is described that Tang Fei gave Mao more than one question, 1 the number divided by 7 =&; &, the remainder can be several, and the largest one can be several. Mao Chao was in trouble and turned to Ma Xiaotiao for help. Ma Xiaotiao wrote a note to Mao Chao. Ma Chao was ecstatic when he heard the note, and soon solved the puzzle.
Through these two stories, I understand that you should use your head more when you do things, and all problems can be solved.
