Multiplication formula table back method reference:1. Vertical recitation: This method has a rule, the vertical column of a few will gradually increase a few, which can help memory according to this rule.

2. Horizontal recitation: This method also has a rule, the first few lines, the next sentence will increase a few times compared with the previous sentence.

3. To form a long-term memory, you can recite two ten-minute times a day (divide the daytime into two periods, each period of ten minutes), and randomly select a recitation time period, and write silently on the paper while reciting, which can deepen the long-term memory.

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. This is the way we should all master to quickly calculate single-digit multiplication. The memorization multiplication formula table can quickly memorize the single-digit multiplication results for future use.

Here's how to memorize the second grade multiplication formula:One relies on understanding the method of mnemonics.

The second is the contrastive memory method, which observes and compares more numbers.

The third is the story memory method, stories are very popular for students, and some formulas are more special, and they can use the form of stories to help them learn to remember.

The fourth is finger memory.

Notes on the recitation of multiplication formulas in the second gradeParents can use all available time to conduct random tests on their children anytime and anywhere in the form of games. And let the children say two multiplication formulas and two division formulas according to a multiplication formula, which has achieved the purpose of learning and applying.

Scrambling the order memorization not only allows children to quickly memorize the multiplication formula.

It can also allow children to blurt out the matching multiplication formulas when they see the equation when they are doing problems, so as to improve the efficiency of children's problem-solving.

1. Stand upright.

One by one gets one, one two gets two, and it goes all the way to nineteen, then two and two get four, and then two and three get six, all the way to twenty-ninety-eight, and then three and three get nine, and three and forty-two, all the way to thirty-nine.

Twenty-seven, and so on, followed by four forty-six vertical columns, five five twenty-five vertical columns, six six thirty-six columns, seven seven forty-nine columns, eight eight sixty-four columns, and finally nine hundred and eighty-one.

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.

2. Horizontal back.

The first rampant, 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.

3. Turn your back.

First memorize one or two to get two, then to memorize two two to get four, then turn down and back two or three.

Six, two, four.

8. All the way up 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.

2nd Grade Memorization Multiplication Formulas:First of all, we want to tell the children that the multiplication formula table is also called the "ninety-nine multiplication formula table", as the name suggests, this table consists of nine rows and nine columns. Moreover, the whole formula table is like a staircase shape, so that children can discover and remember this feature, it is easy for children to memorize the structure of the entire table in their minds and deepen their image memory.

Second, tell your child that when reciting the multiplication formula, you should recite it line by line, and that the first word at the beginning of each line must start with "one", for a total of nine lines, and each line begins with "one". In this way, the child will not be confused when reciting.

Third, 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", so what about the second word? We find that the second word is the number of lines it is in, just look at the position of the box in the picture. Pass.

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

Put real objects or learning tools.

1) Put 1 4 first: Look at the picture of the pendulum and say "one four is four"; Add 1 4 to 2 4s: Look at the picture and say "two four is eight"; Add 1 more 4 to 3 4:

Say "three four is twelve"; After adding 1 4 to 4 4s: Say "4 4 4 is sixteen". As long as the child can count, he can count the results.

(2) Then instruct the child to make up the formula. "One four is four" is compiled into a mantra: one four gets four. Ask your child to say what "one four" means (a four) and what four means (four is four).

After understanding the meaning, you can let your child make up the remaining three multiplication formulas according to the above procedure: "Two four is eight" Two four get eight; "Three four is twelve" three forty-two; "Four four is sixteen" Forty forty-six.

After figuring out the ** and meaning of the mantra, it is easy to memorize. When you forget to memorize it, you can recall the picture of the disc in your mind, because the child's ability to remember the picture is much better than the memorization of words.
