Math Story Composition in Life 1 One weekend afternoon, my mother and I went to the west edge bathroom to take a bath. When we finished taking a bath, we were looking in the mirror. My mother suddenly said to me, "daughter, I will test you on a math problem to see if you can?" I opened my mouth and said, "OK, no problem." Mother said, "Did you see a clock in the mirror? Now the clock in the mirror is 7: 15. Can you imagine what time it is in the afternoon? "
I thought for a while, but I didn't make it. Time goes by. I really didn't expect it, so I had to say shyly, "I can't come." When I looked back at the clock hanging on the wall, it was already 4: 45 pm. Mother asked me if I could analyze how to study this problem now. My mother reminded me, what is the relationship between the hour and minute hands in the mirror and those hanging on the wall? At this moment, I immediately realized that they were symmetrical, which is what I learned recently.
When I got home from the shower, I asked my mother to make me some more. The first way is that the clock time in the mirror is 3: 30, and the second way is that the clock time in the mirror is 9: 40. I immediately began to work out the answers to these two questions on paper in a symmetrical way: 8: 30 and 2: 20.
At this time, my mother asked me if I had a little trouble every time I did the problem. Is there a better way? I thought for a while, but I couldn't figure it out. Mother said at this moment: "Remind the child again, add up the clock time and the actual time in the mirror, can you find any rules?" I quickly began to calculate, 3: 30+8: 30 = 12, 9: 40+2: 20 = 12, and found that the clock time in the mirror and the actual time add up to 12, then I jumped with excitement. I know, I know, as long as the clock time in the mirror and the actual time add up to 12.
I said, "It's so simple! Why didn't I think of that? " Mom smiled and said, "Is it simple? This shows that you should have a train of thought when you encounter problems. In real life, we should be good at discovering things and finding out their laws, then you will feel that mathematics in life is much more interesting than in class. "
Through this incident, I found that' mathematics' in life is indeed everywhere, and it is everywhere in life and study. From then on, I like math more!
In this colorful life, mathematics is everywhere, just like: buying things, dividing things, talking about prices, discounting goods and so on. There is a math problem in math today, which is about prices.
"Elder sister, I'm so hungry. What do we have to eat? " "Why don't you go to the supermarket to buy something to eat!" As soon as I heard that I was going shopping, I was a little worried, because supermarkets and convenience stores are rarely open now. "Go to my bag and get 20 yuan! If it is not enough, take 10. Where does the rest come from? " "Oh, oh." I set off on my bike in high spirits. Dingding .....
When I arrived at Kelly's supermarket, fortunately I opened the door. I want to buy a lot of things. Go in and have a look. All I can eat is instant noodles, film and crispy rice. I can't eat too much instant noodles. Just buy 2 packs! I have an instant noodle with a discount card. Buy one pack and get one free, but I can only use it once, so I have three packs of crispy instant noodles. I have spent 2 yuan. I want to buy two coated tablets, one for 2 yuan and one for 3 yuan. 2+2×2+3=9 (yuan). Let's go to the convenience store again! (Because the door is open) In this house, there are snacks besides shopping. Why don't you buy some snacks? If you can't finish it, you can eat it later. A pack of 1 yuan shrimp flavor strips, that's it! 9+ 1= 10 (yuan) is exactly 10 yuan. Finish the account and go home for dinner!
Yes! Mathematics is wonderful, as long as you find it. ......
