Humorous math stories in grade three

when does the snail climb the well? A snail accidentally fell into a dry well. It lay down at the bottom of the well and began to cry. A toad (lai) crawled over and said to the snail in a muffled voice, "Stop crying, little brother! It's no use crying. The shaft wall is too high. If you fall here, you can only live here. I have been here for many years, and I haven't seen the sun for a long time, let alone want to eat swan meat! " The snail looked at the old and ugly toad and thought to himself, "What a beautiful world outside the well! I can never live in a dark and cold well like it!" " The snail said to toad, "uncle toad, I can't live here. I must climb up!" How deep is this well? " "Ha ha ha ....., what a joke! This well is 1 meters deep. How can you climb it at your young age and with such a heavy shell? " "I'm not afraid of hardship and fatigue. I can always climb out after climbing for a while every day!" The next day, the snail ate enough and drank enough water, and began to climb up the wall. It kept climbing, and finally climbed 5 meters in the evening. The snail was very happy and thought, "At this rate, I can climb up tomorrow evening." Thinking about it, it fell asleep unconsciously. In the morning, the snail was awakened by a purr. At first glance, it turned out that Uncle Tu was still sleeping. It was surprised: "How come I am so close to the bottom of the well?" It turned out that the snail slipped down 4 meters from the well wall after falling asleep. The snail sighed, gritted his teeth and began to climb again. In the evening, it climbed another 5 meters, but at night the snail slipped another 4 meters. Climb and climb, and finally the strong snail finally climbed up the well platform. Can you guess, children, that it will take a few days for a snail to climb the well platform? During the Warring States Period, Qi Weiwang raced with general Tian Ji, and Qi Weiwang and Tian Ji each had three good horses: getting on, winning and dismounting. The race is divided into three times, and each horse race is bet on thousands of dollars. Because the horsepower of the two horses is almost the same, and the horses in Qi Weiwang are better than those in Tian Ji, so most people think that Tian Ji will lose. However, Tian Ji adopted the advice of his protege Sun Bin (a famous strategist), dismounted Qi Weiwang's horse, dismounted Qi Weiwang's Zhongma, and dismounted Qi Weiwang. As a result, Tian Ji won a daughter by winning Qi Weiwang 2-1. This is an example of using game theory to solve problems in ancient China. For an internationally renowned country, once a woman went to buy cotton. Hua Luogeng was working out a math problem. How much did the woman say it would cost to pack cotton? However, Hua Luogeng, who was diligent, didn't hear it, so she answered the calculated answer. The woman screamed, "Why is it so expensive?" At this time, Hua Luogeng knew that someone was coming to buy cotton and said the price. The woman bought a bag of cotton and left. Hua Luogeng was just about to sit down and continue to calculate when he found that the toilet paper for calculating the problem just now was taken away by the woman. This time, Hua Luogeng was so anxious that he went after him desperately. A master of Huang Bao saw Professor Hua Luogeng, a modern mathematician in China who enjoys a high reputation in the world. I let him take a bus (because they knew each other) and finally caught up with him. Hua Luogeng said shyly, "Auntie, please … please give me back the toilet paper." The woman said angrily, "I paid for it, but it wasn't from you." Hua Luogeng was so anxious that he said, "How about this! I paid for it. " While Hua Luogeng was reaching for money, the woman seemed to be moved by the child! Not only did he not ask for money, but he also returned the toilet paper to Hua Luogeng. At this time, Hua Luogeng was slightly relieved. After returning home, he calculated again ... When did the snail climb the well? A snail accidentally fell into a dry well.

Can you guess, children, that it will take a few days for a snail to climb the well platform? The best answer to adopt one * * * is three articles, which should be simple and detailed to standardize the three major distributions.
