Time flies so fast, and one day passes. In this day, is there anything or someone that touches us?

Let's write a diary seriously together.

Before writing, you must first consider the content and structure!

The following is a compass drawing diary for math class that I compiled for everyone for your reference. I hope it can help friends in need.

Mathematics Class Compass Drawing Diary Part 1 On a fresh morning, I got up early, and a new day began again. I rode my bicycle quickly to school.

As soon as I walked to the school gate, I found many sixth grade students buying something from the canteen!

I took a closer look out of curiosity. I really didn't know what to look at, and I was shocked when I saw it.

It turns out that the math teacher assigned an assignment yesterday to buy a compass today.

This was bad. I suddenly became anxious. What should I do?

In desperation, I suddenly thought that my mother-in-law's house is not far from the school. Why don't I ask my mother-in-law to give money to save the emergency?

The extremely flustered mood finally relaxed, so I quickly ran to my mother-in-law's house, but the door of my mother-in-law's house was locked. Was there no one at home?

I knocked hard on the door, but no one answered.

So I hurried to school again on my bicycle. When I got to the classroom, luckily I was not late.

Helpless, I borrowed from the left and right, but everyone only had one compass. I couldn't help but tremble all over and became nervous again.

In class, the math teacher asked the students to take out compasses to draw pictures. I looked left and right. The teacher seemed to have noticed something unusual and walked towards me. At this most critical moment, I suddenly saw that my classmate could not

After drawing a picture, an idea came to her: "I didn't bring it with me, let me draw it for you." She readily agreed. When the teacher came to me, I was drawing a picture seriously with a compass!

I finally passed this class.

Now that I can, I don’t dare to be careless anymore. Although I escaped criticism today, I may not be so lucky next time.

Mathematics Class Compass Drawing Diary Part 2 In the evening, my brother said he was hungry and wanted to drink milk powder. I saw my mother washing clothes, so I helped to make milk powder for my brother.

But I didn’t know how much water and how much milk powder I needed, so I ran to ask my mother.

My mother told me that I need 180 ml of warm water.

I asked my mother how many spoons of milk powder I needed. My mother said: "30 ml of warm water requires 1 spoon of milk powder. How many spoons of 180 ml of warm water do you need? Do the math!" I added it with my mouth and counted a few 30's with my fingers.

: 330=60, 630=90, 930=120, 1230=150, 1530=180.

Finally, when I counted the sixth 30, it added up to 180. I quickly told my mother that it was 6 spoons.

Mom smiled and said: "That's right, but if you learn multiplication and division, the calculation will be easier, 180÷30=6, and you can calculate it quickly." It turns out that it can be so simple!

Mathematics is all around us, I want to learn it well!

Diary of Compass Drawing in Mathematics Class Part 3 Happy Saturday came, and I accompanied my father to work in the store.

As soon as he arrived at the store, my father received a call from a customer.

It turned out that I wanted to buy the portion tray on the warming table.

After answering the phone, my father said to me: "Dad, let's test you today! The customer wants to buy 4 portion basins on the warming table. There are 6 portioning trays on the warming table. How many do you need?"

I thought in my mind that 6+6+6+6=24 (pieces).

Dad asked again: "Do you have any other algorithms that are more convenient and faster?" I then thought about the multiplication formula I just learned during the summer vacation, "four six twenty four". I quickly calculated it, and the answer to addition is

the same.

After my father heard the answer, he gave me a thumbs up.

Dad said: "The number of pots in our warehouse is 12 per box, so how many boxes do we need to send them?" I quickly thought about it in my heart, 24-12-12=0 is exactly 2 boxes.

I quickly told my dad, "Just 2 boxes." My dad laughed happily and treated me to ice cream.

It turns out that mathematics is everywhere in our lives.

Math Class Compass Drawing Diary Part 4 On Tuesday, my mother and I came to the swimming training class to continue learning to swim.

The coach asked me to swim ten times.

After the swimming, my mother asked me a question: "How many sets of swimming movements do I need to do for ten rounds?" My mother wanted to test my calculation ability.

I thought about it, I need to do 16 groups of swimming movements in one round trip (one group of swimming movements includes: 2 kicks, raising the head once to take a breath and moving the hands to both sides once), then 10 round trips means 10 16 groups of swimming.

action.

I thought of two calculation formulas. The first one is the continuous addition formula: 16+16+16+16+16+16+16+16+16+16=160; the second one is the multiplication formula: 16x10=160.

I answered my mother’s question, and I also told my mother two calculation methods.

My mother asked me again: "Which calculation formula do you think is the easiest?" I replied with a smile: "Of course it is the multiplication calculation! It took me a long time to calculate on the paper and I was dizzy."

My mother gave me a thumbs up and praised me and said, "That's great! Mom thought you would only use the most troublesome method to calculate, haha!" My mother and I both laughed happily.
