Description

"Dividing three-digit numbers by one-digit numbers, division with 0 in the middle" PPT courseware for dividing two or three-digit numbers by one-digit numbers

teaching objectives

1. Combined with specific examples, experience the process of understanding that 0 divided by any number will result in 0, and independently try to calculate the quotient of dividing a three-digit number by a one-digit number with 0 in the middle.

2. Understand the principle that any number divided by 0 is 0, and be able to correctly calculate the quotient of dividing a three-digit number by a one-digit number with a zero in the middle.

3. Actively participate in mathematics activities, gain successful experience, and enhance self-confidence in learning.

How many peaches does each person get?

Observe the situation diagram and talk about what is happening in the picture?

Which two students can perform?

0÷4＝0

0 divided by any number that is not 0 is 0.

In conclusion

A written calculation method for dividing a three-digit number by a one-digit number with a 0 in the middle of the quotient:

During the writing process, if the number in any digit of the dividend is 0 or less than the divisor, and there is no remainder in the previous digit, this digit will be occupied by 0.

Knowledge and memory

If there is 0 in the calculation quotient, the key role must be recorded clearly.

0 is coming to occupy the digits, so don’t underestimate it.

If you discard this 0, the calculation will not be accurate.
