Take the sidewalk, cross the street and take the crosswalk, stop at the red light, go at the green light, watch the traffic carefully, don't play in the driveway, and don't cross the pedestrian guardrail.

Don't scramble to get on and off the bus, take a civilized bus, don't lean out of the window, don't grab the handrail on the bus, don't walk around with your schoolbag on your back, don't talk to strangers easily, and don't play with sick stray dogs. (2) Enter the school safely during the break, don't hug, don't squeeze and don't run, go up and down the stairs to the right, and then walk in an orderly way. The corridor is too dangerous to run and fight. Enter the classroom in a civilized way, don't step on tables and chairs, and don't climb high.

(3) Sports safety extracurricular activities are conducted in the playground. Check the venue and equipment. First put on sportswear, take off watches and accessories, make preparations before exercise, stretch your arms and bend over, behave in a standardized and civilized manner, and put an end to dangerous actions.

(4) Food Hygiene Remember to wash your hands before eating, don't laugh when eating, chew slowly and digest well, unlicensed vendors should not import unclean food, bring their own lunch to be heated, and raw fruits and vegetables should be washed.

(5) After school, the song "After School" rings and leaves the classroom in turn; Walking slowly in the corridor, orderly and disappointing; Stairs to the right, don't make trouble or push; Exercise should be moderate and class spirit should be strong; Play games happily and follow the rules; Remember safety and never forget it. Don't touch the knife and fork when you come home from school; There is electricity in the socket, so don't touch it; The balcony is very dangerous, but you can't climb it if you can see it; Gas is poisonous, so don't light a fire. A person squatting at home, the door is the protector; If someone knocks at the door, look through the cat's eye first; If a stranger comes, don't open the door; Shouting loudly, gangsters are most afraid; Bad guys can scare away and be safe and secure; Parents will praise you when you go home! (6): Save yourself from drowning Don't panic when drowning in Song Dynasty, and leave the scene quickly.

In case of fire, don't panic, don't be greedy for property, and don't jump off a building. Follow the instructions and run quickly. It is not safe to take the elevator.

If you have difficulty breathing when surrounded by thick smoke, you should stick your body to the ground, wet your nose and mouth with a towel, leave the fire for help, and call "1 19" quickly to ensure safety. If you really can't escape, run to the balcony and call for help.

(8): Earthquake rescue Don't panic when the earthquake comes, run outside the house. If it's too late to hide, hide under the table or bed.

The flood is low first and then high. Hold fast to mountains and trees and watch the weather forecast.

The fire is coming. It's cruel. Don't play with Mars. Call 1 19 to stay away from the fire and call for help.

Take the sidewalk after school and watch the traffic lights at the intersection. A person locks the door at home, and strangers don't answer the phone.

Dogs bite cats and catch poisonous snakes, so it is best to seek medical advice in time. (9): Save yourself from scalding Song Xiaoer, burn it, don't waste it.

My finger is hurt and a little red. Touch my ear. Large area, cold water washing, plastering.

Use soy sauce and honey instead of plaster. If it is very hot, don't hesitate to take it to the hospital.

One flush, two chaperones, children, remember. Wash your hands before eating and remember not to drink raw water.

The lightning flashed, not a false alarm. Avoid the tall trees and squat down. When there is an earthquake, don't panic and evacuate to the open area urgently.

3. 50 words of a math story

1, interesting math story-200 words Thales saw people reading the notice, so he went up to have a look.

The initial notice said that Pharaoh wanted the smartest person in the world to measure the height of the pyramid. So I went to Pharaoh.

Pharaoh asked Thales what tools he used to measure the pyramids. Thales said he only used a stick and a ruler. He put the stick next to the pyramid. When the shadow of the stick was as long as the stick, he measured the length of the shadow of the pyramid and half the length of the bottom of the pyramid.

Add these two lengths to get the height of the pyramid. Thales is really the smartest man in the world. He can easily measure the height of the pyramid without climbing to the top.

2. Interesting mathematical story -200 words During the Warring States Period, Qi Weiwang and General Tian Ji raced horses, and Qi Weiwang and Tian Ji each had three good horses: mounted, won and dismounted. The race is divided into three times, and thousands of dollars are bet on each horse race.

Because the horsepower of the two horses is almost the same, and Qi Weiwang's horse is better than Tian Ji's, most people think that Tian Ji will lose. However, Tian Ji took the advice of his disciple Sun Bin (a famous strategist) and dismounted Qi Weiwang's horse, Ma Zhong of Qi Weiwang and Qi Weiwang. As a result, Tian Ji beat Qi Weiwang 2-/kloc-0-and won a lot of money.

This is an example of China's ancient substitution game theory to solve problems. 3, interesting math story-200-word animal school held a children's song competition, and the elephant teacher was the referee.

The little monkey raised his hand first and began to recite: "I can calculate carry addition, and the digits can only be added if they are aligned." The number of digits should be aligned with the number of digits. When the number of digits exceeds ten, the number of digits should be advanced to ten.

Ten digits plus one plus one can count quickly and accurately. As soon as the monkey finished speaking, the puppy began to recite: "abdication and subtraction are not difficult, and the number alignment can be reduced."

If the single digits are small enough, ten people can borrow one. If ten people return, one will be ten, and if they return, one will be missing.

How to reduce ten digits, ten digits will be reduced again and again. Everyone applauded their wonderful performance.

Teacher Elephant said, "Their nursery rhymes make us understand that both carry addition and abdication subtraction should win the championship, ok?" Everyone agrees and applauds them. 4. Interesting mathematical story-200-word meteorologist Lorenz put forward a paper entitled "Will butterflies flap their wings to cause tornadoes in the taxonomic group?" This paper discusses that if the initial condition of a system is a little worse, its result will be very unstable. He dubbed this phenomenon "the butterfly effect".

Just like we roll the dice twice, no matter how deliberately we roll, the physical phenomena and points thrown twice are not necessarily the same. Why did Lorenz write this paper? This story happened in the winter of 196 1 2008. He operated the meteorological computer in the office as usual.

Usually, he only needs to input meteorological data such as temperature, humidity and air pressure, and the computer will calculate the possible meteorological data at the next moment according to the built-in three differential equations, thus simulating the meteorological change map. 5. Interesting math story-200 words Tang Yan and his disciples are walking in the endless desert. They are hungry and tired. Pig thought: How nice it would be to have a good meal! The Monkey King is not as greedy as Bajie. Wukong just wants to drink a glass of water.

The Monkey King wanted to think, a family appeared in front of him. There is only a glass of milk on the table at the door. The Monkey King hurried forward to drink this glass of milk, but the host said, "Wait a minute, Great Sage. If you want to drink this glass of milk, you must answer a math problem. " The Monkey King thought, just a math problem can't beat me.

The Monkey King agreed. There is a problem in the host's house: pour a glass of milk, you first drink 1/2 and then drink 1/3 and finally drink all the drinks. Do you drink more milk and water? Why? 6. Interesting math story-300 words in the evening, I saw a difficult problem in the Olympiad book: the number of apple trees in the orchard is three times that of pear trees. Master Lao Wang fertilizes 50 apple trees and 20 pear trees every day. A few days later, all the pear trees were fertilized, but the remaining 80 apple trees were not fertilized.

Excuse me: How many apple trees and pear trees are there in the orchard? I am not intimidated by this question, but it can stimulate my interest. I think the apple tree is three times as big as the pear tree. If two kinds of trees are to be fertilized on the same day, Master Lao Wang will fertilize "20*3" apple trees and 20 pear trees every day.

In fact, he only fertilizes 50 apple trees every day, which is 10, and the last 80 trees. Therefore, Master Lao Wang has been fertilizing for 8 days. 20 pear trees a day, 8 days is 160 pear trees. According to the first condition, there are 480 apple trees.

This is to solve the problem with the idea of hypothesis, so I think the hypothesis method is really a good way to solve the problem. 7. Interesting mathematical stories-300 words Archimedes has many stories, the most famous of which is the story of discovering Archimedes' principle in the bath.

The king made a golden crown. He suspected that the craftsman had stolen some gold with silver, so he asked Archimedes to identify whether it was made of pure gold and not to damage the crown. Archimedes thought hard about the crown all day. One day, Archimedes went to the bathroom to take a bath. He went into the bath tub. When he immersed himself in the bath bucket, some water overflowed from the side of the bucket. Archimedes saw this phenomenon and crackled in his mind. "I found it!" Archimedes put an equal weight gold nugget and a silver nugget into a container filled with water, and found that the silver nugget discharged much more water.

So Archimedes took a gold nugget with the same weight as the crown and put it in a container filled with water to measure the displacement; Then put the crown in a container filled with water to see if the amount of water discharged is the same, and the problem will be solved. With further research, Archimedes principle, the most important cornerstone of fluid mechanics, was born.

8. Interesting math story-300 words When Gauss was still in the second grade of elementary school, one day his math teacher wanted to take time out of class to deal with some of his private affairs, so he planned to give the students a difficult problem to practice. His topic is:1+2+3+4+5+6+7+8+9+10 =? Because addition has just been taught, the teacher thinks it will take a long time for students to solve this problem.

I can also take this opportunity to deal with unfinished business. But in the blink of an eye, Gauss had stopped writing and sat there doing nothing.

The teacher saw it and called Gauss angrily. But Gauss said he had already answered.

Help me find some nursery rhymes about my study and life in Grade Two.

do morning exercises

The air in the morning is really good. Let's all do morning exercises.

Stretch your arms, bend over, kick and jump, and exercise every day.

Wash your hands before meals.

Small washbasin, please clean the water. The children are smiling and holding out their little hands.

Wash, white and clean, wash your hands before eating, pay attention to hygiene and don't get sick.

Small ants, with great strength, can pull several times by themselves. If you want to know where the power comes from, you won't climb down. Little ants, the most obedient, do whatever their mother says, not afraid of being stupid. They often learn kung fu. Grapefruit is yellow and big, one by one, hanging on the tree. Orange orange yellow, orange round, like an orange, sour and sweet. Loquat loquat fruit, yellow and round, tastes sweet and fresh. Hawthorn hawthorn fruit, round, one by one, like a red ball. Jujube jujube, small, sweet and crisp, good nutrition. Pine tree small pine tree, green and blue, not afraid of thunder and wind. Willow willow, swaying in the wind, watering frequently, grows fast. Rose, rose, planted on the ground, I watered it. White rabbit, white rabbit, white ear, love to eat radish and cabbage. It's so cute. Rabbit, honey, rabbit, open the door. Come on, mom's coming in. No, no,no. I won't. No one will come until mom comes back. Find a friend, find a friend, find a good friend, salute and shake hands. We are all good friends.

5. The third grade elementary school mathematics ballads daquan

The catchy nursery rhymes in the third grade of primary school mathematics can help students better remember the knowledge points. Because of children's songs, the boring concepts in our math class have become vivid.

I collected some children's songs of this grade, plus some self-made, hoping to help everyone's teaching. When a number is divisible by several digits, children's songs look at the highest digit of the dividend first. If the high order is not enough, the quotient is written as which number it is divided by. If the quotient is not enough, write it as 0. In quotient, the first and last digits, the remainder is less than the divisor, so the operation is correct.

Decimal addition and subtraction children's songs (self-edited) Decimal addition and subtraction, the point should be aimed at the point, and the last digit should be supplemented by 0, which is convenient for subtraction. Decimal size is larger than nursery rhymes (self-made), and the digits should be aligned.

The first is higher than the high position, and the same proportion is lower. Which is taller or bigger?

Keep it in mind. A line of regional children's songs (self-edited), covering a large area; The length ratio is 10, and the area ratio is 100.

Solve the problem of children's songs, read them several times and find the key; Look at what you want first, and then find conditions; Reasonable calculation formula, careful calculation; Ask for more answers to a question, and the unit will not forget it; Check the results and finally write the answer. The order of the four operations is multiplication before division, addition after subtraction.

What should I do if I encounter parentheses? It first appears in parentheses. The abdication subtraction should be kept in mind, starting from the unit; Who is not enough to retire, don't forget to add ten to the standard; If the interval is 1, it is best to remember that 0 becomes 10.

For the subtraction of continuous abdication, see 0. Go ahead and see which one has it. Borrowed and walked back, 0 is a bit like 9.

Two-step calculation of application problems, two-step calculation of application problems, careful reading and examination of problems. The intermediate problem is the key to solve the problem.

The quantitative relationship should be accurate and the calculation steps should be clear. Grasp both ends of the middle band and answer the questions accurately.

Children, open your hands. Everyone has five fingers, and there are several gaps between them. Please take a closer look. I am 0 in the division where the middle or the last bit of the quotient is 0. I have great ability and the division operation is amazing.

Not enough quotient 1. I'll make it up to you. I will sit when there is a vacancy.

If others want to get rid of me, I will always be the winner. In the fourth operation order, parentheses grab the first place, multiplication and division rank second, and finally addition and subtraction are counted. Who counts the year, month, day, three, five, seven, eight, ten, wax first, 3 1 day is always big.

April, June, September, November, 30 days is never bad. February, the most special, February and February changes.

February 29th in leap year and February 28th in normal year. Except the year number is even, the whole century number is marked with double zeros.

There are two ways to be punctual, twenty-four and ordinary. The time unit is lined up, and the largest unit is the century.

1 century, 100 year; How many days is 1 year? 365 in a normal year and 366 in a leap year. 1 hour 60 minutes 1 minute equals 60 seconds.

Remember the year, month, day, hour, minute and second, and the progressive rate. The measuring unit sings to the children, queues up quickly, and holds hands with the measuring unit.

Let's see who speaks fast. That's right. The unit of RMB is Yuan, Jiao and Min, and the forward speed is 10, remember.

1 yuan got 10 angle; The angle of 1 is 10, and 1 yuan is equal to 100. What is the unit of length and the progressive rate? Megameter, centimeter and millimeter.

The maximum unit is kilometers. 1 m = 10 decimeter, 1 decimeter = 1 0cm,1cm =10mm.

The meter and the kilometer are also adjacent, and the rate 1000 is a special case. What is the unit of mass and what is the progressive rate? Tons and kilograms and grams should bear in mind the ratio of 1000.

Physical units are easier. Adjacent 100 is the area and adjacent 1000 is the volume. Large units, small units and size conversion are all regular.

From large to small, the decimal point moves to the right; Divided by the forward speed, the decimal point moves to the left. Propulsion rate 10, shifted by one place; The propulsion rate is 100, shifting by two places; The propulsion rate is 1000, which is displaced by three places.

..... Numbers divisible by 2, 5 and 3 are 0 and 5, which are definitely divisible by 5. The units are 2, 4, 6, 8 and 0, and they must be divisible by 2.

If the sum of each number is a multiple of 3, it must be divisible by 3.

6. Seek catchy nursery rhymes suitable for the first and second grades of primary school.

Children's songs (nursery rhymes, poems), at least 30 words, or compositions, which are often used by primary school students to exercise and keep fit. , preferably more words.
