I am Mengyu teacher, today teach children mental and brain calculation, learn to add within 10. Don't wrench your fingers, learn hard!
Oral is the first grade of primary school, and it must be done every day, so if children want to learn mathematics well, they must pass the oral calculation.
Oral arithmetic is mental and mental arithmetic, and children's oral arithmetic ability needs to be trained, and it is also necessary to teach children scientific mental and brain calculation methods.
Some children seem to be calculating verbally, but the little finger is constantly sticking out and retracting, and the child is breaking the finger to calculate, which is not a mental calculation.
The heart and brain calculation does not require the child to break his finger, it is the child who looks at the problem, the heart and brain are calculating, and the answer comes out instantly.
The calculation of mathematical problems requires the use of oral skills, and oral skills are the method of arithmetic. A parent communicated with me, and then said that oral arithmetic problems do not need oral tips, but to use ideas, is to exercise children's minds. This is pure nonsense!
Whether it is elementary school, or junior high school math problems, the calculation method is to use the law of words and formulas.
What is addition?
Addition is the operation of combining two or more numbers into one number, which is called addition.
Learn addition within 10
Let's start by counting the numbers 1-10 along the way
1、2、3、4、5、6、7、8、9、10
The method of addition within 10 is calculated
Addition tips within 10: Remember the large number plus the decimal number, and the addition of a few is to count a few more up.
Example Question 1; 4+2
[4+2] Large number (4) Keep in mind, add a decimal number (2), add a few up and count a few, add 2 up and count two numbers, 4 count two numbers up.
That is [4] 5, 6 (4 + 2 = 6)
Get the answer; 4 plus 2 equals 6
Example 2; 3+5
【3+5】 Keep in mind the large number (5) and add the decimal number (3) plus 3 and count the three numbers up.
That is [5] 6, 7, 8 (3 + 5 = 8)
Get the answer; 3 plus 5 equals 8
The following questions, children can use the method taught by the teacher to calculate it.
The large number is written in the heart, and the decimal is added upwards, and the decimal number is a few upwards and a few more.
Isn't it easy for children?
Be sure to remember the method of the recipe, practice more, oral arithmetic is not a problem.
