Description
"Written division of two-digit numbers by one-digit numbers, division with remainder" PPT courseware for dividing two- and three-digit numbers by one-digit numbers
teaching objectives
1. Combined with specific problems, experience the process of exploring the calculation method of dividing a two-digit number by a one-digit number with a remainder.
2. Master the calculation method of dividing a two-digit number by a one-digit number with a remainder, and be able to perform calculations correctly.
3. Able to communicate with others about the process of thinking about problems and understand the connection between mathematics and real life.
There are 82 small rubber balls in the kindergarten.
(1) How many boxes are needed to pack every 6 boxes?
82÷6=13 (pieces)……4 (pieces)
Answer: 14 boxes are needed.
(2) How many boxes are needed to pack every 8 boxes?
82÷8=10 (pieces)……2 (pieces)
Answer: 11 boxes are needed.
Why should the quotient be 0 in the units digit?
The 2 in the ones place is not enough to divide 8 into a quotient of 1, so it falls directly to the remainder.
