What is a good way to exercise children s number senses?

There are several ways to exercise your child's number sense:

With the specific number of counting, can do one-to-one correspondence, early counting to visual, auditory, tactile combination.

Begin to understand the relationship between ordinal numbers and cardinal numbers, and know that the last number to count is the total.

Given a specific scene, the number of items within 10 can be counted.

Further guide children to understand the arrangement of number sequences and memorize numbers.

Provide your child with a variety of counting tools, such as introducing number lines.

Changing different counting modes to hop or interval with and 10 is a preliminary study of the law of the number series.

How to develop students' number sense: use numbers to express and communicate letters.

Allowing students to learn to express and communicate information with numbers can not only enable students to appreciate the value of learning mathematics, but also be a concrete manifestation of number sense. In order to let students perceive the digitization of information, I have created a platform for a variety of mathematical activities in teaching, through which students can feel that numbers can express and communicate information, and that numbers are in life. For example, in the lesson "Understanding Clocks", I designed such a platform for activities:

I let students make clock faces, talk clock faces, dial the time, and work together in groups on the basis of independent thinking, so that students have more opportunities to show their ideas, and through recognizing, reading, and writing the moments of various clocks, so that students can gradually acquire and cultivate number sense.

How to develop students' number sense: connecting with real life.

Mathematics is in practice, and back to practice, students like to learn some mathematical knowledge related to real life. If it is a familiar case around them, it is easy to arouse students' interest in learning, and the birth of each mathematical concept, theorem and formula has its actual background, so when teaching, start from the reality, abstract mathematical concepts through the practical problems that students are familiar with, and perceive new knowledge. For example, when learning the concept of distance from a point to a straight line, you can use the familiar example of standing long jump to understand, use the balance that students are familiar with to explain the properties of equations and inequalities in inequalities, and draw out the method of comparing the size of line segments from comparing the height of two classmates, etc., so as to learn new knowledge from students' familiar life experience, and on the other hand, cultivate their awareness of applying mathematical knowledge to practice.

How to develop students' number sense: develop students' estimation skills.

There are many ways to cultivate students' estimation ability, and questioning and reflection are also effective strategies for cultivating students' estimation ability. In mathematics activities, students should be allowed to obtain mathematical conjectures through observation, analogy, and reflection, and further seek evidence, give proofs or give counterexamples, so that they can really use mathematical language to question, judge, and reflect logically. In teaching, teachers should respect the personality characteristics of each student, and carefully design exercises in questioning, judging and reflecting, so that students can cultivate their estimation ability and have a good sense of numbers through questioning and reflection.

How to cultivate children's number sense?

Next, I will share a few convenient and effective methods for training number sense thinking for parents' reference.

Method 1: Parents can design a "little shop" game. Lead the children to have a preliminary understanding of the renminbi, and know that the renminbi has three units: yuan, jiao, and points.

Take turns playing the role of cashier and customer. Customers are asked to buy 1 pencil and 2 exercise books. A pencil is 1 yuan, and an exercise book is 2 yuan, to see if the child can complete the task of giving money and finding money in order during the role-playing, and at the same time exercise the sense of number, it can also make the child more proficient in addition and subtraction.

Method 2: Let the child feel and experience the length unit for himself. Let the abstract numbers in the books become concrete things that can be seen and touched.

For example, you can take your children to the stadium and experience the actual distance of 50 meters, 100 meters, and 200 meters. You can also practice visual inspection with your child, first draw the range, guess how many meters there are, and then use a tape measure to measure and verify. In the mistakes again and again, the child's estimation can become accurate, method three:

Weight unit training in everyday life. Let the children weigh and weigh various items and fruits, and feel the actual weight of 500 grams, 1 kilogram, 3 kilograms, etc. By solving practical problems, children can grasp the size of numbers more deeply and concretely, and produce positive emotional experiences, optimize number sense, and cultivate interest in mathematics learning.

Method 4: Use educational toys to cultivate number sense thinking. In schools and families, we can also use some math teaching aids, such as puzzle beads, calculators, etc., to help children intuitively feel the changes in numbers and quantities, and cultivate their number sense.

Method 5: Use the Internet Mathematics Enlightenment APP to train systematic number sense thinking. We can use a number of educational apps and learning ** to provide a variety of math learning resources, through which children can learn and practice math and improve their number sense skills.

Among them, the Number Sense School of [Number Sense Planet] provides 3 major training topics, 4 major training modes, more than 110+ knowledge units, 5000+ training content, and can improve children's number sense ability through gamified mathematics exercises, and comprehensively uses the most advanced artificial intelligence, visualization, and gamification technology to improve the experience and efficiency of children's mathematics learning.

How to build and cultivate children's number sense?

Connect with life and get a sense of numbers. Number sense cannot be cultivated through teaching, the important thing is to let children perceive, discover, and explore on their own, so that children can experience that mathematics exists in their surrounding lives. Number sense is a kind of spiritual feeling, a kind of consciousness activity, which exists in the human mind and is a high-level intellectual activity.

People with a good sense of number will naturally appear when they need to play a sense of number, and a good sense of number can help students deepen their knowledge and use it comprehensively, so as to achieve a thorough understanding of knowledge, and to achieve such a state, it takes a long-term training process. With the establishment, development and reinforcement of number sense, students' overall mathematical literacy will also improve!

How to cultivate children's number sense?

Suggestion: Children should start to develop their number sense from the age of 3-4 years.

Before the age of 3, most children understand things intuitively, and by the age of 4, children can almost distinguish the shape, color and size of objects. At this point, you can start with a concrete object and increase your child's exposure to numbers in real life.

When I was 4 years old, my mom was peeling cowpeas, splitting them into two piles. I came over and counted 15 in one pile, 16 in the other, and asked my mother curiously why it was divided into two piles. How many are there?

Mom said that because it needs to be eaten in 2 days, and then arranged a vertical type on the white paper, my mother said to me that single digit + single digit, ten digit + ten digit, single digit more than 10, ten digit on the ant or sentence to carry +1.

Through this simple cowpea calculation, I slowly learned to operate two digits, and then three digits and four digits came naturally.

Numbers are everywhere in life.

Parents should make full use of various things and things in life to inspire their children's interest in numbers.

When children are exposed to a new thing, they are particularly fond of practice, but they will pester their parents with problems. I remember when I was a child, every time I went out to take the bus, I took the initiative to squeeze to the front door, just to be able to see the driver's and conductor's numbers to do addition and subtraction. Anyone born in the 80s should remember that at that time, the job number was basically four or five digits, and I looked at these numbers in the car and calculated the four-digit addition and subtraction directly by mental arithmetic.

Even if I don't take a car, when I usually walk, I look at the house number and do mental arithmetic.

In life, calendars, parents' ages, and clocks all contain numbers, as long as they are skillfully guided, children can not only understand the numbers in life, but also cultivate a sense of numbers, and enhance the parent-child relationship, which is really a triple win.

A few days ago, I saw a ** in the circle of friends, and rolling dice is a very good way to train children's oral arithmetic. Through dice, parents can let their children learn addition and subtraction, calculate the sum of 3 dice, and after rolling again, they can compare the size of the two and calculate the difference between the two. It's also a great way to teach!
