In an interview, Qiu Chengtong, winner of the Fields prize, the highest honor in the world of mathematics, and a scholar of academia sinensis, pointed out that Mathematics should be taught according to aptitude, and both memory and reasoning should be taken into account. It is a kind of "unfortunate" not to recite mathematics of nine-nine multiplication; If you don't use the method of multiplication table you can only have one number and one number and you don't have a complete concept of multiplication.

He said, well, for example,if I have 2 times 10, and I have to add 10 times each time, how can I get to the next level of math? after 40 years of studying mathematics, he still has to learn some things by heart.

British science education has a long history, is a country with scientific and advanced civilization, and has cultivated many outstanding scientific talents, like Newton, who discovered gravity and is a great scientist and mathematician in British history.

The great mathematician Gauss once said that mathematics is the foundation of science, and arithmetic is the foundation of mathematics.

In recent years, the United Kingdom has been plagued by a problem, that is, the basic computing power of the nationals is obviously insufficient. The students are also lagging behind other countries in terms of their performance, especially those countries like Singapore and China. After an in-depth study of educational surveys, the British government has announced that British students must be proficient in the “multiplication table” before they graduate from elementary school

If you let some children calculate how much 4+8 is equal.

Some children count this way: Children will use their mouths and have words in their mouths:

"4...8, 9, 10, 11, 12, the answer is 12."

Some children count this way: stick out a finger, a finger, a hand index, ... the answer is 12.

If children use 123 Easy Teaching to learn arithmetic, the children don't need to have words in their mouths, and they don't use their fingers. The answer is 12.

Just like learning the "multiplication table", children need to practice repeatedly to form long-term memory.

What is the difference between the teaching method of 123 Easy Teaching and the traditional one?

Since 2016, the United Kingdom has also asked children to memorize the multiplication table to improve their computing power. Using the "multiplication table" has a faster calculation effect on the arithmetic of children's skilled multiplication, and it is very helpful. Using 123 Easy Teaching is like a system learning method of "multiplication table" to train other operations, and naturally it will get good results. 123 Easy Teaching has the equivalent training effect on the arithmetic as the "multiplication table".

If the children learn other arithmetic in the similiar way of learning by "multiplication table", as long as the children can become proficient, the children can quickly answer the arithmetic questions. 123 Easy Teaching is to explain the Addition, subtraction, multiplication, division, representation of various operational images, and the process of constructing arithmetic, to enhance children's understanding. The child is able to be familiar with the results of calculations, and leave a deep impression on the mind by reading 123 Easy Teaching .

We wish that the children will be familiar with 123 Easy Teaching as same as they are familiar with the "multiplication table". They must be able to be skilled in basic arithmetic after reading 123 Easy Teaching repeatedly. Application on123 Easy Teaching, the children can quickly and intuitively say the answers, no need to use the fingers, 123 Easy Teaching can change the habit of calculation, the child is very intuitive to calculate, became the mental arithmetic.

Reading 123 Easy Teaching, like the effect of reading the "multiplication table", can definitely improve the children's arithmetic ability, and there is significant progress. If the child is proficient, the child can quickly learn basic arithmetic, so that the basic arithmetic can be calculated with the heart. After a short period of proficiency, the child can do operations more quickly and more accurate than the traditional calculation method, and get the answer without using fingers.

Multiplication table

In order to facilitate the memory, the "Multiplication Table" is a multiplication of the two numbers one by one.

From the 1st to the 9th, the child perceives the order of numbers.

1 is followed by 2, 2 is followed by 3.. and so on.

1*1= 1 1*2= 2 1*3= 3 .................. 1*9= 9

2*1= 2 2*2= 4 2*3= 6 ................... 2*9=18

3*1= 3 3*2= 6 3*3= 9 ..................... 3*9=27

............

........

.....

9*1= 9 9*2=18 9*3=27 ..................... 9*9=81

。

Many mathematics teachers agree with the importance of arithmetic operations. They also believe addition is the basis of multiplication. Usually, we learn the addition, then we learn the subtraction, and then we learn the multiplication and division.

If the students learn the addition well, and they will be able to learn mathematics smoothly in the future. Therefore, the addition is the basis of all kinds of arithmetic. The importance of addition is self-evident.

The great mathematician Gauss once said that mathematics is the foundation of science, and arithmetic is the foundation of mathematics. We may say the addition is the foundation of arithmetic.

The addition (the "addition table" ) in 123 Easy Teaching is designed as same as the "multiplication table".

123 Easy Teaching : 1 to 12, addition,

1+1= 2 1+2= 3 1+3= 4 .................. 1+12= 13

2+1= 3 2+2= 4 2+3= 5 ................... 2+12=14

3+1= 4 3+2= 5 3+3= 6 ..................... 3+12=15

............

........

.....

12+1= 9 12+2=18 12+3=27 ..................... 12+12=24

...

"Constructive mathematics" has operational thinking, which helps students understand and agree with the calculation structure. The students not only know the truth, but also know why, so that they can calculate correctly and skillfully.

For example, 4+8 is equal to how much. If the process of "constructing mathematics" is written into a mathematical formula, it becomes:

4+8 = 4+(6+2) = (4+6)+2 = 10+2 = 12

I hope that the children will be familiar with the addition (the "addition table" ) in 123 Easy Teaching as same as they are familiar with the "multiplication table". They must be able to be skilled in basic arithmetic after reading 123 Easy Teaching repeatedly. Application on 123 Easy Teaching, the children can quickly and intuitively say the answers, no need to use the fingers, 123 Easy Teaching can change the habit of calculation, the child is very intuitive to calculate, became the mental arithmetic.

123 Easy Teaching : 1 to 12, multiplication,

1*1= 1 1*2= 2 1*3= 3 .................. 1*9= 9 ......1*12= 12

2*1= 2 2*2= 4 2*3= 6 ................... 2*9=18 ......2*12= 24

3*1= 3 3*2= 6 3*3= 9 ..................... 3*9=27......3*12= 36

............

........

.....

12*1= 12 12*2=24 12*3=36 ............

.... 12*9=108......12*12= 144

........。.

How 123 Easy Teaching improves children's interest and memory?

123 Easy Teaching is a systematic and organized computing training. It is easy to form understanding and memory.

In the 123 Easy Teaching, the "multiplication table" is combined with the image, and the rich multiplication of images and constructive mathematics is used to enhance children's interest in learning and to more easily understand the concept of multiplication. Therefore, parents can let the children use the image to strengthen the memory while cultivating the child's knowledge, and cultivate the child's abstract ability and imagination for the image, which will not make the child feel boring.

Applying a good method children can learn arithmetic with less effort, 123 Easy Teaching is with shortcuts to computing that can't be learned in the classroom. The transition from children to the changes in the way the adult brain works, so that children can easily fall in love with mathematics and improve their mathematics.

Like learning a "multiplication table", it is necessary to practice 123 Easy Teaching repeatedly to form long-term memory.

According to the logical sequence and regularity of the traditional 9* 9 multiplication table , the logic of various operations is editted in 123 Easy Teaching. The primary school students are familiar with such a nature when they learn the addition and subtraction.

Practice makes perfect, if the 123 Easy Teaching is applied to learn addition and subtraction well, the students are able to be very accustomed to use such a nature to learn the nine-nine (or 12* 12 ) multiplication table in the future.

The 4 basic operations of arithmetic (+ − × ÷) give your child a strong foundation for mathematical success and also are important to have confidence to face the exams.

The website has a complete architecture of arithmetic operations and interesting pictures. Try it out.

Let's take a look at this website.

It is worthy of your likes and recommendations, guiding children into a happy paradise for learning arithmetic operations.

What is the similarity between 123 Easy Teaching and the 99 multiplication table?

The similarity between 123 and the 99 multiplication table is that they both are systematic and sequential, smooth operation editing step. In particular, 123 Easy Teaching explains each operation step clearly, even with images to express, rich and interesting, easier to understand, more amiable, friendly, easy to understand, easily to keep deep impression.

How to use 123 to achieve the maximum effect?

On the one hand, we must first understand, and follow the training in the way of training the ninety-ninth multiplication. It must be very skilled and even remember. You can achieve the best results by reading every page of 123 Easy Teaching up and down, over and over again, and then practicing the calculus exercises with the exercises.
