Today, I finished my homework early in the morning, and when my mother saw it, she came over and said to me, "Xiao Ming, let's play a game with you!" "Okay! I readily agreed.

Mom brought a piece of cardboard, and a movable pointer was fixed with a nail in the center of the cardboard. The cardboard is divided into 24 compartments, with numbers 1-24 written in the compartments. "Mom, what are the rules of the game?

Say it quickly! I said anxiously. "The rules of the game are simple, it is:

The pointer to the odd or even cell is to add the next number. If it adds up to odd numbers, I win, and if it adds up to even numbers, you win. Mom said with a smile.

When I saw that the rules of the game were so simple, I played it more than ten times in a row, but I couldn't win against my mother every time, and my mother laughed. "Why is it always singular? I asked my mother puzzled.

Mom said, "Think for yourself!" So, I racked my brains and finally reminded me of a formula that my teacher once taught:

Odd + Even = Odd. Now I can understand that if the pointer is in the singular cell, then adding a number must be an even number; If the pointer is in a double number, then adding a number is an odd number, so no matter which box the pointer goes to, the number added up is an odd number. Mom took advantage of this law to win.

In the world of mathematics, there are many wonderful laws, as long as we learn mathematics well and make good use of mathematics, it is everywhere!

Today is the Mid-Autumn Festival on the 15th day of the eighth month of the lunar calendar. After dinner, our family sat in the small courtyard in front of the door and watched the moon of the Mid-Autumn Festival together.

There are many flowers and plants planted in the small courtyard, including osmanthus, orchids, and two iron trees, one large and one small, which make the whole courtyard full of vitality. A small stream flowing outside the courtyard was like a beautiful song played for this calm night.

Our family tasted fragrant tea in the small courtyard, ate moon cakes, greeted the bright moonlight, accompanied by the sound of gurgling water, and listened to grandpa tell the story of Yue'er, which was really pleasant.

When talking about the Mid-Autumn Festival, my father proposed: "Let's come to Bo Cake." I asked, puzzled

What is a bobiscus? Dad explained: "Bo cake originated in Xiamen, and it is said that Zheng Chenggong invented an entertainment activity three hundred years ago for fear that the soldiers would miss their families during the Mid-Autumn Festival.

Bo cake takes moon cakes as prizes, and the tools needed are dice and large bowls, and the champions and leaders are determined by the number of points thrown to obtain prizes. It is also an event for all ages." "Oh, I see!

I said with a sudden realization.

Let's start the cake! Everyone elected grandma to open the blog, only to see grandma staring at the big bowl, picked up six dice in the palm of her hand and shook it, threw it down, but did not win the lottery. Next came the uncle, who shouted as he picked up the dice

Take a flatbread and go home. Confidently, he threw the dice down. "One, two, three, four, five, six".

hit the "list eye". As the "custodian" of the prize, I gave him mooncakes. And so the game went on round by round.

Seeing that there are fewer and fewer mooncakes, but I haven't gotten any yet, I'm already starting to get anxious. It was my turn again, and I picked up the dice and thought to myself: I must win, this time I must win!

I slowly threw the dice down, and the result was five sixes, and I won the "champion". Finally put the last mooncake in the bag. After statistics, my uncle got the most moon cakes, there were eight of them, and I only had one moon cake in my account.

The worst thing is Dad, there is not a piece of bread.

At this time, the bright moon has risen to the middle of the sky, illuminating half of the sky, and the moonlight sprinkling illuminates our small courtyard, and the laughter of the small courtyard continues to drift away with the gentle evening breeze ...... into the distance

Rabindranath Tagore once said, "The bee sipps the nectar from the flower, and when it leaves, it says thank you." The pompous butterfly believes that the flowers should be thanked to him.

When we have a mutually beneficial relationship with others, both parties should be grateful. The earth selflessly provides us with a place to live, so that our lonely hearts have a home; The earth zealously provides us with energy and makes our hungry stomachs happy. We repay the earth with high-speed development, so that the heart that pays can be harvested.

Friends, family, and everyone behind them are a force of support and a backing for self-confidence. They warm our growing hearts with love without complaint, and encourage our young hearts with actions. "Whoever gives me a drop of water, I will give him the whole sea.

This is a famous quote that Hua Mei said. As the old Chinese saying goes, "The grace of a drop of water is reciprocated when a spring springs." "Echo each other from afar.

If, in times of difficulty, someone behind you lends a helping hand to you, you should be ten times more grateful to help him.

Do you know that every flower and grass is a young heart. When you brutally strangle these hearts that are eager to survive, isn't your heart dripping blood?But if you save these hearts, will you dare to be happy?

God will punish you for violating the right to life of others!

Therefore, when you embrace the whole world with a grateful heart, and when you repay the whole world with a grateful heart, the true meaning of the world is by your side.
