Reciting multiplication formulas must start from one to one and one to two in order. For example, 1 1 gets one, 12 gets two until 19 gets nine, then 22 gets four, 23 gets six until 298, then three gets nine, three gets twelve until 3927, and so on. This method has a rule that the first vertical column is a multiplication formula of one and the second vertical column is a multiplication formula of two, so that recitation will not be repeated and omitted.

We will also find a rule that the number of fractions in each column is different from top to bottom, which is exactly the number of columns in which this column formula is located. For example, the first column adds 1 from top to bottom, and the third column adds 3 from top to bottom. Mastering this rule is more helpful to memory and memory.

Second, understand the memory method

After learning the meaning of multiplication, I have a certain understanding of the meaning of the formula. If you can't recite 8×9, you can find a familiar formula, such as 998 1, then the sum of 8 9s is "9 9s minus 1 9", that is, "8 1-9=72", and it is easy to find a calculation method according to these. After you get the answer, you should read 8972 several times and keep it in mind.

Third, the story understanding method

Some multiplication formulas are quite special, and these special formulas are quite impressive to children. For example, four Tang Priests in The Journey to the West met with 81 difficulties; 1982 the Monkey King changed, and in 4936 Pig Bajie changed. There are also such things as: anyway.

Fourth, find the characteristics of the product.

We can help children remember or judge the right or wrong results through some characteristics of products and factors. For example, the formula of 1 is the simplest, and the product is the same as another factor; The result of the formula of 2 is an even number, that is, we often say "2, 4, 6, 8,10"; The formula of 5 ends with either "5" or "0". Look at another factor. If it is an even number, the end of the product is 0. If it is singular, the product ends with 5.

Another method is to judge the parity of product according to two factors: even× even, even× odd, even × odd and odd. Of course, it is enough for children in grades one and two to remember the first few, and the last few are suitable for thinking expansion, such as when doing Olympic mathematics.

Five, the game memory method

Speaking of games, it should be a way that many children are more willing to accept. Parents can play the game of "counting 24 points" with their children to increase the chances of their children using the formula. Practice makes perfect.

Six, life application method

The application of multiplication formula permeates all aspects of our lives, and the knowledge taught in class is limited. Parents can ask their children more multiplication formulas in their lives, or give them a chance to show them and let them have more contact with the practical application of formulas.
