Nezha, an interesting math story in Grade Two (1), continued to run to Jubaoge, when he suddenly felt a huge shadow covering him. When Nezha just wanted to look up to see what this shadow was, the monster swept it gently with its tail, and a powerful current swept Nezha far away. It turned out to be a shark in the East China Sea.
The shark grinned, revealing two rows of sharp teeth, and asked without cutting. The little boy, Nezha Nezha, who is said to be omnipotent, calmly replied:? Yes! ? General shark:? It's not enough to eat you, so I'll try you out: the tail is half the length of the body, the head is half the length of the tail, and the head is 3 meters long. Can you tell me how long I am? I'll let you go if you answer it. If you can't answer, I'll eat you as a snack today! ?
Nezha:? It's too simple. Your head is 3 meters long, which is half the length of your tail, which means that your tail is 6 meters long and half the length of your body, which means that your body length is 12 meters, so you have 3+6+ 12=2 1 meter. ? General shark:? I'll let you go today, and when you get the child back, I'll have a fight with you sometime. I can't believe I can't beat you! ? Nezha thought:? What a big guy, 2 1 meter long. Without weapons, it is really not necessarily his opponent. ?
The second day of the second day (2) Interesting math story Nezha longs for treasures and cherishes the beautiful scenery of Guo Huashan. Straight into water curtain cave, Nezha came to the pine forest. Suddenly, a masked man appeared from the forest with a bowl of thick mord in his hand and said, I opened this road and planted this tree. If you want to pass by here, stay and buy the toll! ? Nezha was frightened and thought: How can there be robbers in Huaguoshan? Must be the Monkey King's helper again. So he said:? Sorry, I came in a hurry and didn't bring any money. ?
Hearing this, the masked man raised his staff and hit him. Nezha fought with the man for a long time, but it didn't tell the winner. I saw the big fellow jump to one side, take off the black cloth on his head and say, stop, the third prince is skilled in martial arts! ? Nezha turned out to be Friar Sand. Nezha asked? Sha Wujing, are you here to stop me from getting the treasure? Friar Sand:? The golden cudgel is my brother's exorcism weapon. If you can't say it, give it. Unless you can answer my question, I will let you meet my brother. ? Nezha readily way:? It's a deal! ?
Friar Sand:? Third Prince, the mord in my hand was given by the Jade Emperor when I was a general in Heaven. It is divided into three parts: crescent knife, staff handle and shovel. Among them, the length of crescent knife accounts for the total length of Zen stick, which is less than the length of shovel 10 cm, and the handle of stick is more than the sum of shovel and handle 10 cm. Do you know how long the mord in my hand is? Nezha thought, while calculating on the ground with branches. The crescent knife takes up the total length, which is less than the shovel length 10 cm? , it can be concluded that shovel and stick handle account for 10 cm of the total length, and shovel accounts for 10 cm of the total length. At the same time, 10 cm of the total length of the stick handle can be deduced. The handle of a stick is more than the sum of the length of the blade and the handle 10 cm? Know that the handle is longer than the total length of the mord (? ) 10 cm is extra. Assuming that the total length of the mord is x cm, then X- 10= (? ) X+ 10, here, Nezha said confidently. The length of your mord is 180 cm! ? Hearing Nezha's calculation process, Friar Sand exclaimed. The third prince is not only skilled in martial arts, but also extremely clever! ?

Grade 2 (3) Interesting Math Story Nezha bid farewell to the folks in Qiantangguan, and soon came to the foot of Guo Huashan on hot wheels. The beautiful Guo Hua is full of the fragrance of fruits all year round, and Nezha puts down his clouds. Just as Bajie wanted to pick some fruits to quench his thirst, he suddenly cried out: Who dares to steal the fruits from Guo Hua Mountain? ? Nezha embarrassedly said:? It turned out to be Bajie. How did you come to Huaguoshan? I just wanted to pick a fruit to quench my thirst, but I didn't expect to disturb you. ?
When Pig saw that it was Nezha, he laughed. It turned out to be the third prince. At the invitation of the monkey, I have been waiting for you here for a long time. If you want to eat fruit, I have prepared it for you. I picked a basket of pears just now, and I ate them because of the hot weather. The remaining 24 is more than half of what I ate. Do you know how many pears I ate? If you can answer, I'll let you see my monkey brother. If you can't answer, please come back ?
Nezha thought:? Bajie must be the Monkey King's reinforcements. It's definitely not possible to rush in. ? So he said to the pig, as soon as I answer, you let me go. Bajie: Of course, I will not only let you go, but also treat you to pears. ? Nezha thought for a moment and answered? You ate 16 pears. ? The pig thought:? You can't guess the answer so soon. Let me give him some color to see see. ? And said:? You're guessing, right? You have to tell me the process you asked for! ? Nezha ha ha laugh: Why is it so difficult to take a basket of pears seriously? 1? According to the food, we can know how much is left, and then according to the fact that 24 people have eaten more than half, we can deduce that there are more pears left than the original basket. = 24 more. With 24? (-)=48, you can find out that there are 48 pears in a basket, and then use 48? = 16, you have eaten 16. ? Nezha promised, took a pear from the basket and said to Pig who was still in a daze. I can go there now! ?
