If they make mistakes, they should be punished as they deserve.

How to let children learn to count quickly

First of all, to learn the basics of addition and subtraction, you must learn the number of 1- 100, the reciprocal of 100- 1, and the number of points within at least 20. It is not easy for children to learn. Parents can make their children feel familiar with toys. When doing the questions in the future, children can clearly express their thoughts and use the method of ten plus one.

How to teach children to learn arithmetic? Parents and some new teachers can use sports to let children think in advance before doing things, which is helpful to train children's thinking agility. Many children may be more naughty as they grow up. At this time, it is necessary for our parents and teachers to influence him carefully.

When children start to deal with arithmetic problems, we start with addition and subtraction within ten, such as 2+3=? 5+4=? At first, these were all calculated by children with wrenches. Later, when I saw this simple arithmetic problem, I gave the answer.

Can be slowly extended to more than ten addition and subtraction. Here I'll teach you a method, even if you haven't learned abacus mental arithmetic. Remember this rule, no matter how difficult it is, it will be worked out quickly. First of all, let children remember these numbers and find good friends. 1 and 9 are good friends, 2 and 8, 3 and 7, 4 and 6, 5 and 5 are good friends of each other. Be sure to remember these first.

Let's add and subtract more than ten, such as 8+9=? , is a number, you need to carry arithmetic problems. The first person who thinks of ten needs to enter one, give ten digits a higher one, and how to calculate the single digits. Let the children find out the good friends of nine first. The answer is 1, enter one for ten digits, and then the single digits are reduced, and 8 MINUS 9' s good friends 1 equals, and the children will work out 8- 1 immediately. Calculate a 24+8=? One digit is all ten, four MINUS eight is a good friend 2, which means 4-2=2, and the ten digits of two plus one are three, so the answer is 32. Is it simple?

The above is the addition that needs to be carried, and then the subtraction that needs to be abdicated, such as 20-7=? First, start with single digits. 0-7 is not enough. You need to borrow one from ten digits, so the single digits need to be returned to 0, 0+3=? The child will immediately answer 3, the unit is 3, the ten borrowed from 2 is 1, and the answer is 13. Calculate a more difficult 56-27=? 6 minus 7 is not enough. If you borrow one from the top five, you can return 7' s good friend 3 to 6, which means 3+6=9. If you borrow one from the top five, it will be 4. 4 minus 2 is 2, and the answer is 29. Isn't it simple?

It's easier to add and subtract abdication without carrying, only one bit is needed to subtract one bit, and ten bits are subtracted from ten bits, which must be counted from one bit.

Children's observation ability is not as good as that of adults, so it is not easy to give an intuitive answer at once. In order to facilitate observation and solve problems more clearly, children can learn to list vertical formulas, as shown in Figure 88-49=? , you can list the vertical formula as shown in the figure, ten to ten, one to one correspondence, at a glance, you can quickly calculate the answer according to the method taught before.
