1. Professor added:
Add up the two figures. If the sum is greater than 10, write down the number first, and then add the tenth digit to the calculation of the next digit. For example: 7+6= 13, write down the number 3 in each number, and then add 1 to the calculation of the next number.
2. Teach subtraction:
Subtract one number from another. If you need to borrow money from ten digits, you can subtract 1 from the subtracted ten digits and then calculate. For example: 9-5=4, because the decimal place of 9 is 1, you can subtract 1 from 1, and then subtract 5 from the remaining number 4.
3. Teach multiplication:
Multiply two digits, then divide the product into ten digits and one digit and add them. For example: 7×8=56, because 5 is a decimal multiplied by 7 and 8, and 6 is a single digit multiplied by 7 and 8, you can add 5 to the decimal of 6 to get 56 as the final answer.
4. Teaching Department:
Divide one digit by another. If only the remainder has no quotient, you can add the remainder to ten digits and then calculate. For example: 9÷3=3, because 9 is divisible by 3, the quotient is 3. But if it is 10÷3, the remainder 1 can be added to the decimal number of 10 to get 3 as the final quotient.
The above are some easy-to-understand methods to teach the Ten Methods, but the most important thing is to let children understand the principles of these calculation rules. Examples and exercises can help children understand.
For example, you can use a set of numbers to demonstrate and practice for children, such as giving 3+4 and 7+8 addition problems for children to practice addition. Through repeated practice, children can master the ten-break method skillfully, which can not only improve the calculation speed, but also improve their mathematical ability.
In short, education suitable for children should be simple and easy to understand. Through vivid examples, it is very important to make children fall in love with mathematics and master the basic knowledge of mathematics.
