"Written division of three-digit numbers by one-digit numbers, division with remainder" PPT courseware for dividing two or three-digit numbers by one-digit numbers

teaching objectives

1. Combined with specific examples, experience the process of independently exploring the calculation method of dividing a three-digit number by a one-digit quotient of a two-digit number with a remainder.

2. Be able to correctly calculate the division of three-digit numbers divided by one-digit quotients of two-digit numbers, and be able to check divisions with remainders.

3. Actively participate in mathematics activities and develop number sense in the process of estimating the number of quotients.

Pack 258 mooncakes into boxes.

(1) How many boxes are needed to pack one box for every 7 pieces?

258÷7＝______(number)

(2) How many boxes are needed to pack every 8 pieces into a box?

258÷8＝______(number)

In conclusion

1. The written calculation method of dividing a three-digit number by a one-digit number with a remainder:

First divide the number in the hundreds digit of the dividend by the divisor. If the quotient is not 1, add the number in the hundreds digit and the number in the tens digit to calculate. Write the first digit of the quotient in the tens digit, and then add the remainder and the ones digit. The numbers above are added together and continue to be divided. Each time the remainder is smaller than the divisor.

2. Checking method for division with remainder:

Quotient × divisor + remainder = dividend.

give it a try

First estimate how many digits the quotient is, then calculate and check the calculation.
