How to memorize a ninety nine multiplication table, how to quickly memorize a ninety nine multiplica

The multiplication formula table is a simple multiplication table that starts from "one by one to get one" and ends with "ninety-nine eighty-one", which is derived from the multiplication formula and is convenient for multiplication calculation.

Vertical back: For example, ,—— gets one, one or two gets two, and then recite it until it gets nineteen, then it gets four for two and two, and then it gets six for two, until it reaches twenty-ninety-eight, then it gets nine for three-three, and it gets three-forty-two, until it reaches three-nine-twenty-seven, and so on, and then it is four hundred and forty-six, five and twenty-five, six and sixty-six, seven and seventy-nine, and seventy-seventy-nine, and finally ninety-nine-eighty-one.

Horizontal back: For example, the first horizontal line, one sentence one by one; the second is two sentences, one two gets two, two two gets four; And so on, the first few lines are a few sentences, and the last nine sentences go from nineteen to ninety-nine eighty-one. There is also a rule in this method, the first few lines, the next sentence is a few more than the previous sentence.

When children reach the third grade of primary school, they will learn multiplication, so let's talk about how to teach children to memorize the ninety-nine multiplication table. How it works:

Split into the same prefix.

Before memorizing the multiplication formula, together with the child, divide the multiplication formula table into nine large pieces, each of which starts with the same number, and break the whole into scattered small pieces, which is easy to remember.

Let's start with the beginning.

Multiply one by other numbers, the result is the same, the child understands the fastest, and remembers the fastest, parents can start with the beginning of the multiplication teaching, and slowly increase the difficulty.

Start with nine. If the child's memory is particularly good, you can also start with nine, because nine is at the end, there is only one small square, remember the fastest, the more left, the more small squares to remember, remember one more every day, the child will not find it difficult.

Write more silently. In the past, teachers often said that a good memory is not as good as a bad pen, that is, let students write more, because writing is much more intuitive than memorization, and you can remember yourself through your eyes, so that you can remember it more firmly, so that children can memorize some, let children write it down silently, so that it is not easy to forget.

Memorizing multiplication formulas is a basic arithmetic skill in the second grade of primary school, and it must be memorized.

1. First of all, let the child understand the meaning of the formula, such as: 3 times 6: means the addition of 3 6s or the addition of 6 3s. Let the child understand the meaning of multiplication, know how the number comes about, and help the child find the rules, and the child will remember it when he understands.

2. Back one line and one line, don't be greedy. Conquer little by little from 1 until 9.

3. It must be practiced repeatedly and repeatedly.

4. Give children questions, and use multiplication formulas as examples in the process of calculation, so that children can taste the significance of memorizing formulas to speed up calculations.

5. The most direct method is rote memorization and let the teacher talk about it in class.

Develop good math habits. Establishing good math habits will make you feel orderly and relaxed in your learning.

Good habits in mathematics should be: questioning, thinking hard, being hands-on, re-inducting, and paying attention to application. In the process of learning mathematics, students should translate the knowledge imparted by the teacher into their own special language and keep it in their minds forever.

Good learning mathematics habits include self-study before class, concentration in class, timely review, independent homework, problem solving, systematic summary and extracurricular learning.

Introduction to the ninety-nine multiplication table and how to memorize it.

To recite the ninety-nine multiplication formula, you can back horizontally, vertically, or bend your back (back horizontally to the head, and then down).

It's easiest to memorize horizontally, because when elementary school students start to learn multiplication formulas, they learn them in the order of horizontal rows (the first line is the 1 formula, the second row is the 2 formula, and the third line is the 3 formula......).With an upright back, you can train your memory and become more proficient in mastering the mantra.

The methods of memorizing multiplication formulas include vertical recitation, repeated recitation, summary rule recitation, etc.

Vertical recitation: For example, one by one gets one, one two gets two, and you memorize it until you get nine at nineteen, then you can get four by memorizing two-two, and then you can get six from two-three, until you get nine from three, and so on, and then you will have a vertical column of forty-forty-six, and a vertical column of five-five-twenty-five. There is a rule in this method, the number of vertical columns, the number of gradually increase a few, which can help memory according to this rule.

Repeat recitation: As long as you read and write every day, memorize one line at a time, memorize the first line, then memorize the next line, and memorize the next line with two lines together and then memorize ,......Keep memorizing like this repeatedly, plus parents reminding and asking questions, and the child will soon grasp it.

Summarize the rules of recitation: When reciting the multiplication formula, the last formula at the end of each line is the formula obtained by multiplying the same number, for example, when you memorize the third line, you must use the multiplication of three and three as the last formula.

First of all, it is necessary to dispel the notion that the multiplication table is not memorized, but understood. The most important thing in learning mathematics is thinking, and the same is true for multiplication formulas.

To memorize the multiplication formula, the child should first understand the meaning of the formula, such as: 3*5: It means the addition of 3 5s or the addition of 5 3s. If your child understands the meaning of multiplication, he can quickly find out how to get the number and then help him find the pattern of the product.

The multiplication formula table is also called the "ninety-nine multiplication formula table", as the name suggests, this table is composed of nine rows and nine columns. Moreover, the whole mantra table resembles a staircase shape. For children in the second grade of primary school, it is difficult to memorize the multiplication formula table, and it also takes a process.

Ask your parents to buy you a ninety-nine multiplication table, read it every morning, memorize it, and after a week or two, you will naturally memorize it.

For example, first memorize one, two, get two, then memorize two, two, get four, and then turn down and back two, three.

Six, two, four.

Eighth, all the way to 298; And then back to one or three.

Three, two, three.

Sixth, three three get nine, then turn down three four hundred and twelve, until three nine twenty-seven; And so on, go back to 14 and 4 and then turn around. One of the characteristics of this kind of memorization is that there are nine sentences in the formulas from one to nine, and the number of formulas gradually increases.

Other back methods. 1. Stand upright.

For example, one by one gets one, one two gets two, and then memorizes until nineteen, then two and two get four, two three gets six, and then twenty-nine and ninety-eight, then three and three get nine, and three and forty-two, all the way to three ninety-twenty-seven, and so on, and so on, and then there are four hundred and forty-six, five and twenty-five, six and sixty-three, seven seven and forty-nine, eight eight sixty-four, and finally nine nine and eighty-one.

2. Horizontal back.

For example, the first rampant, one by one, get a big size; the second is two sentences, one two gets two, two two gets four; And so on, the first few lines are a few sentences, and the last nine sentences go from nineteen to ninety-nine eighty-one. There is also a rule in this method, the first few lines, the last sentence will increase a few times compared to the previous sentence.

If you discover and memorize the features, it is easy to memorize the structure of the entire table in your mind and deepen your image memory.

1. The multiplication formula table is also called the "ninety-nine multiplication formula table", as the name suggests, this table is composed of nine rows and nine columns. Moreover, the whole mantra table resembles a staircase shape.

2. When reciting the multiplication formula, you should recite it line by line, and the first word at the beginning of each line must start with "one", a total of nine lines, and each line begins with "one". In this way, you won't be confused when reciting.

3. It should also be noted that the first formula of each column is related to the row in which it is located. What I just said is that the first word in each column starts with "one", and the second word is the number of lines it is in, just look at the position of the box as shown in the figure. Pass.

The two characteristics of two and three can easily remember the first formula in each line.

4. When reciting the multiplication formula, the last formula at the end of each line is the formula obtained by multiplying the same number, for example, if you memorize to the third line, you must multiply three by three as the last formula, and when you memorize the fifth line, you should multiply five by five as the end of the line. Knowing the end of each line, you immediately reflect the beginning of the downward movement.

5. Discovered such a rule, that is, horizontally, the second word of each line is the same, for example, in the second line, all the second words are "two", and in the fourth line, all the second words are "four", so it will be easier to remember.

6. You will also find a rule, that is, the number of each column, the number of differences from top to bottom, is exactly the number of columns where the column formula is located, for example, in the first column, from top to bottom in order +1, in the third column, from top to bottom in order +3, mastering this law is more helpful for memorization and memory.

The multiplication formula table starts from "one by one to get one" and ends with "ninety-nine eighty-one", which originates from the simple multiplication table that is not imitated next to the multiplication formula and is convenient for multiplication calculation.

Vertical back: For example, ,—— gets one, one or two gets two, and then recite it until it gets nineteen, then it gets four for two and two, and then it gets six for two, until it reaches twenty-ninety-eight, then it gets nine for three-three, and it gets three-forty-two, until it reaches three-nine-twenty-seven, and so on, and then it is four hundred and forty-six, five and twenty-five, six and sixty-six, seven and seventy-nine, and seventy-seventy-nine, and finally ninety-nine-eighty-one.

Horizontal transport on the back: for example, the first horizontal line, one sentence one by one; the second is two sentences, one two gets two, two two gets four; And so on, the first few lines are a few sentences, and the last nine sentences go from nineteen to ninety-nine eighty-one. There is also a rule in this method, the first few lines of the big ant, the latter sentence will increase a few times than the previous sentence.
