How to train children to observe the relationship between number and quantity in life

Develop a sense of volume through hands-on touch.

When parents help their children establish a new sense of quantity, they can divide it into three steps: "estimating, measuring, and adjusting", such as letting children feel and learn 1 cm, you can first let children blindly evaluate one according to their life experience, keep it still, and then use measuring tools to measure it to verify whether the estimate is accurate. The third step is to adjust the child's estimate and let the child remember how long the correct centimeter is. In the process of revision, the child's estimation will become more and more accurate, and gradually establish a perception of 1 centimeter.

Connecting life with a sense of abundance.

Mathematics is a subject that is closely related to life, and connecting abstract mathematical knowledge with common scenes in life can help children understand and remember. For example, parents can work with their children to find out what things in life are one centimeter long. For example, how much is the area of a book?

How long is the ball of the foot? How high is a floor, etc.

In the process of applying what you have learned, you will deepen your sense of quantity.

The units of measurement come from the needs of daily life and production, and these units have strong practical significance and life, so the practical use of the units of measurement is also a good way to cultivate a sense of quantity, and at the same time, it can also cultivate children's awareness of the use of mathematics, try to use mathematical ideas and methods from a mathematical point of view, and seek problem-solving strategies. For example, parents can encourage their children to estimate the distance from home to school. Because children know that it takes about 25 minutes to walk from home to school, we can deepen our sense of volume by using steps and time to feel farther and more abstract distances.

Sense of quantity is a new core literacy in primary school added to the 2022 new curriculum standard, and its importance is self-evident. Parents should act quickly and pay attention to the cultivation of a sense of quantity in daily life to help their children go further on the road of learning mathematics!

The educational content of kindergarten is comprehensive and enlightening, how will we guide children as teachers to discover the numbers in life? Here are a few of my takes:

1. Understand the numbers in life from life.

The guide proposes to "guide children to become interested in numbers, quantities and other phenomena in the surrounding environment, preliminarily construct the concept of numbers, and learn to use simple mathematical methods to solve problems in life". For example, when taking a walk at lunch, it is common to hear children chattering about it

We've come a long way! "There are so many trees over there! "My steps are bigger than yours" and so on, so I thought:

How do you let them know how long and short they are, how tall and short? The next morning conversation, I threw the question to the children. They have many ideas, some say to measure with a rope, some say to measure with a ruler, and so on.

This shows that the child is interested in this activity. Through the hands-on operation of the children with the help of tools, the length and height of the object were measured. Learn about the application and role of measurement in your life.

2. Perceive the numbers in life from the game.

The guidebook proposes that "you can feel the relationship between the quantities of things in the game, and experience the importance and fun of numbers." For example, if kindergarten children can play skipping rope and long jump in the morning, we can prepare a record book for each child and encourage them to record the activity by counting and measuring to evaluate the ranking. Feel the continuity between numbers and understand the simple relationship between numbers and rankings through the method of counting.

When the children were discussing what their neighborhoods were like, I asked as a participant, "How many floors are there in the building?" At this time, the children will be very excited, some will say, "My family lives on the fourth floor, 401", and some will say:

My house lives on the eighth floor, 803", and in such exchanges, children will feel the usefulness of numbers in life.

3. Home cooperation captures the numbers in life.

The guide proposes that "the family is an important partner of the kindergarten, and it is necessary to strive for the participation of parents and help them improve their educational ability". We can communicate with parents and guide parents to train their children to observe the numbers in life, such as the change of traffic light seconds, the number of trees on both sides of the highway, the difference in license plate numbers, etc.

Let children really feel the role of numbers in life, and know that learning mathematics is not a dead grass but a fun and happy thing.

The content comes from the user: boutique primary and secondary school information.

To make children fall in love with learning mathematics, we must first inspire children's interest in mathematics, establish mathematical cognition for children, make mathematics life-oriented, game-oriented, child-like, and most importantly, interesting, and cultivate children's mathematical thinking.

Mathematics education is consciously carried out in life.

Interact with your child through parent-child games.

Teach your child to play a game of comparison.

Before teaching your child to count, make sure that your child understands the numbers.

To inspire children's interest in mathematics, not only counting and addition and subtraction, but also to connect more with reality, let children discover the relationship between numbers and shapes in life, and guide children to understand and use the actual meaning of abstract numbers, and connect mathematics with his daily life, which is the most appropriate way for parents to give their children mathematical enlightenment.

Let your child have a simple concept of "number" and "quantity"! 1-20 These numbers are what children can know and understand what they mean! For example, if there are 5 apples on the table, you can ask your child how many apples are on the table!

It will be more convenient for children to carry out mathematics education after they have a certain understanding of "numbers"!

To cultivate children's interest in mathematics, they can read picture books, tell some stories of mathematicians, and sing nursery rhymes, so that children can become interested in mathematics!

In daily life, we should pay attention to guiding children and use mathematics to solve some small problems that happen around children!

You can also play some puzzle games, tangrams, stacking blocks, jigsaw puzzles, etc., which can exercise your child's mathematical thinking skills!

If it is inconvenient for parents, they can help their children enroll in a professional mathematics enlightenment course is also a good way, and at present, it is better to do spark thinking, you can learn about it!

The content of children's mathematics activities is the best in life, applied to life, mathematics and life have a close relationship, teachers only guide children to perceive that many problems in life can be solved by mathematical methods, children will fall in love with mathematical activities. So how do you go about it?

First of all, teachers should be able to use the eyes of mathematics to find the mathematical elements in life, in the children's life, every day contact with all kinds of things are related to mathematics, for example, their own age, the number of people in the group, these questions all involve the concept of quantity; Another example is that a child has a bowl and a spoon during a meal, and there is a corresponding comparison between the bed, bedding and pillow and the child during nap; Another example is the construction game, where children will see blocks of different colors, sizes and shapes, and use them in a large number of spatial orientations such as up and down, left and right, inside and outside. In short, mathematics is everywhere in daily life, so with the help of these lenses, we teachers should think about what mathematical elements can be excavated? Integrate these life-related contents into mathematics activities, so that children can use their existing knowledge and experience to explore and gain a good emotional experience in the fiddling and operation of physical objects, so as to perceive the usefulness and interest of mathematics in life and become interested in mathematics activities.

There are many opportunities for mathematics education in children's daily life, such as learning to classify in the process of organizing and operating materials; When taking an outdoor walk, let the children say who is in front of them and who is behind them, and let the children count the number of steps there are in the stairs, so as to gain the experience of spatial orientation and the concept of numbers; However, these do not need to be confined to the "teaching" and "learning" of the classroom to complete, and teachers do not need to deliberately prepare a large number of operating materials to improve children's experience. We should not only let children learn mathematics in life, but also guide children to use mathematics in life and feel the role of mathematics in real life, for example, let children classify and place the tableware after meals, ask parents to take children to watch movies, let children find their own positions according to the numbers on the ticket, etc., children will feel the usefulness and fun of mathematics in these activities they like.

If you eat 2 boxes of pears and 5 boxes of apples every day, then there are 20 boxes of apples left when the pears are finished, how many boxes of pears did the canteen buy?

If you eat 6 boxes of apples every day, the apples and pears are eaten exactly on the same day, and now there are 20 boxes of apples left when the pears are eaten, which means that they have eaten for a total of 20 days, so there are 20 pears in total 2 = 40 boxes.

What is the value of 3434 350-35350 34?

Original = 34 101 35 10-35 1010 34=(34 1010 35)-(35 1010 34)=0

Original = 19 10101 (37 10101) 185 = 19 185 37 = 95

Example 4] Today is Monday, then what day of the week after "1 3 4 5 7 8 9 10 12" days?

The four terms of , (12 9) are divisible by 7 and can be omitted.

There is only 10 left, 10 divided by 7 and 3, so that "1 3 4 5 7 8 9 10 12" is Thursday after the day.

If there are a number of workers in a production workshop, there is one more person for every four people, one more person for every five people, and one more person for every six people, then there are at least as many workers in the workshop.

The least common multiple of 4,5,6 is 60, and the remainder is taken according to the remainder, so the minimum number is 61

There are many examples in life that are related to time, such as:

The relationship between the travel time and distance of the vehicle.

Activity progress vs. time.

The growth of small trees is related to time.

The relationship between the time of use of the air conditioner and the electricity consumption.

The other is something that is quantitatively related to spending, such as:

The relationship between the cost of buying vegetables and the weight of vegetables.

the relationship between electricity consumption and electricity bills, etc.

Let's look at other relationships carefully, there are many, many more.
