How to cultivate children's sense of number is the predecessor of sense of number.
A good sense of rhythm is the basis of a strong sense of numbers. The stronger the baby's sense of rhythm, the more conducive to the establishment of a sense of number. To give a simple example, the rhythm is jumping, starting, rising and falling. The intensity must be orderly and stable, and it must be completed with a certain concentration. Having these abilities before the age of two shows that the baby has certain perceptual ability.
Life accomplishment is the source of number sense.
In fact, in life, there are many opportunities to cultivate your baby's awareness of counting, such as reading the floor number with your baby when you get on the elevator, and counting down with your baby when you queue up to pay the bill in the supermarket. For example, when cleaning the shoe rack, we will find a pair of shoes, instead of putting them in the east and the west, or from long to short, or from short to long. For example, when eating, let the baby set the bowl and count the number of people in the family. For example, connecting with parents' numbers. So it makes sense to say that living habits are study habits.
The importance of success
If you take your baby to the infant swimming pool when he is young, you should have this experience. Some babies try not to cry when swimming for the first time, and some babies are excited and happy. Those babies who cry for the first time will refuse to swim for a long time, while those who are happy for the first time will swim calmly and rarely repeat. This is the importance of the first success, integral! Now is the first step to practice number sense. If successful, children will be patient and careful. If you fail, you have to spend more time and patience to practice, and it is often difficult for children to persist.
Point method
Find a snack that the baby likes, such as a steamed bun. Tell the baby we'll eat 1 steamed buns first. Parent-teacher conference demonstration. Put the steamed buns on your palm and say 1. Special reminder, don't say 1 while holding it. After success, avoid 2 and say that we should take 3 steamed buns, each of which should be placed on the palm of our hand, before saying the numbers. It doesn't matter if you slow down, even the slower the better. Parents can organize baby games according to the situation, ranging from 1 to 10 and 1 to 5. Why avoid 2? Because we say two words orally, it is easy to confuse the concepts of two and two. So it's best to ask the baby after 1 to 10. Did you find a number missing? Where does it stand? We now take 2, 1 and 2.2. We said there were two.
Parental responsibility
In fact, many parents say they can't teach their children. In fact, as long as there is more care and patience in life, children will be nourished.
How to cultivate children's sense of number? Count? Sense of number in perception
A sense of numbers is not taught. It pays attention to students' own perception, discovery and active exploration. In textbooks, many scene diagrams can make students realize that mathematics exists in their lives around them. Using these numbers can not only solve mathematical problems, but also explain some mathematical phenomena that they didn't understand before.
We can start with the teaching materials and make full use of the scene pictures in the book. Preparatory class? Let students feel the application of mathematics in life by counting. A photo of freshmen entering school can not only make them feel the beauty of going to school, but also make them feel that there are many beautiful things on campus, and the number of these things is different. As long as they observe carefully, they will find the number of everything, and thus perceive that different numbers can be represented by different numbers. ? Understanding of 1-5? In the theme picture, when beautiful rural pictures fall into children's eyes, every child's face is filled with joy. At this time, the teacher asked: What do you eat at grandma's house in the country? What is the quantity? These lovely animals and plants instantly aroused children's enthusiasm for learning and immediately devoted themselves to learning. In the process of students' reporting, the idea that counting in a certain order cannot be repeated or omitted is also permeated.
Second, in? Draw a picture? Experience the sense of number in the middle.
Friedenthal made some comparisons with modern arithmetic methods, and he found that all good methods emphasized counting. However, some teachers ignore the process of counting and only pay attention to the results, which leads students to regard counting as a single and boring number. The author is a teacher? Count? In this link, fully combine some exercises in textbooks and workbooks, and let students draw how many objects there are in their own way in the process of counting. Although most of the students counted correctly, for them, this is just a boring activity that has been repeated several times since kindergarten. The sound they made can be blurted out just by memory. And let them draw a picture by themselves according to the numbers, which effectively overcomes this kind of thinking inertia and allows them to combine their hands and brains and unconsciously experience the feeling of numbers.
Third, in? Calculate? Moderate best number sense
Julia. Angelina Riley also said in How to Cultivate Students' Sense of Numbers that sense of numbers refers to calculation strategies. Flexibility and? Creativity? Oppose to overemphasizing the calculation program without thinking. Piaget, a famous psychologist, also said: Children's thinking begins with action. If the connection between action and thinking is cut off, thinking will not develop. ?
As we all know, the concept of number is quite vague for children in lower grades. Only by giving them more opportunities to use their hands and brains and let them feel and experience in independent thinking can they form an understanding of logarithmic sum operation and thus establish a sense of numbers. In order to cultivate students' sense of numbers, there are many interesting and close-to-life scene pictures, such as the theme picture on page 25 of the chapter on addition. After the students ask mathematical questions (there are three squirrels in the tree, two squirrels jump up, one is * * *, and there are several squirrels), record the mathematical facts they find with mathematical symbols, 3+2=5 or 2+3=5. How to calculate it? At this time, students will have to sort out their own results again.
Health 1: 2 plus 3, counting from 2, is 5.
Health 2: I remember 3 in my mind, and then count 2. The number is 5.
Health 3: I count them one by one.
Health 4: I know that 2 plus 3 equals 5, so 2+3 equals 5.
Teacher: With so many algorithms, which classmate do you like? Why?
Most students like the method of giving birth to 2. On this basis, the teacher guides them: they can look at large numbers or count decimals. The methods of giving birth to 1, giving birth to 2 and giving birth to 4 all embody the counting method of reciprocal after addition, which plays a role in optimizing the sense of numbers.
Fourth, in? Practice? A moderately enhanced sense of numbers
Real life is the source of children's learning. Only by linking what they have learned with real life can they master and internalize knowledge better. Teachers should guide students to find and put forward simple mathematical problems from real life and explore effective methods to solve these problems. In the process of studying practical problems, we should learn to treat and deal with the phenomena and problems in daily life and society from a mathematical point of view, get used to thinking about problems with mathematical methods, and consciously use mathematical knowledge to solve problems.
How to cultivate children's sense of numbers 1 Tell numbers with stories.
According to one of the most popular examples on the Internet, a little girl's 3*5= 15 video is too difficult. In the video, the mother kept asking how much 3*5=, but the little girl didn't get it right, and the mother didn't explain why 3*5= 15. It can be seen that the little girl memorized the multiplication table of 99 completely from memory and didn't understand the meaning at all. In other words, if you ask her what 10* 10=, then the little girl can't answer. For children, stories attract them most. They are easier to understand and more willing to think, such as 1+3=? Instead, 1 soldiers were standing guard, and then three soldiers came to stand guard together. How many soldiers are there now?
2. Understand numbers with graphics and pictures
Because the number itself is a concept, which is very abstract and difficult for children to understand, we can make it easier for children to understand through graphics and life pictures. For example, use dots, use sieve diagrams, finger diagrams, block diagrams and so on.
3. Understand the different meanings of numbers (units of measurement)
Parents all know, but a number of one can't explain specific things, because it lacks a unit of measurement, such as 1 drop of water, 1 glass of water, 1 liter of water. They are all 1, but they represent completely different orders of magnitude. In the cultivation of children's sense of number, we can combine the clock when children understand the concept of number, so that children can begin to understand the timing units that they will often come into contact with in daily life.
