Description

"Problem Solving" Fraction Mixed Operation PPT Courseware

learning target:

1. Be able to flexibly use the knowledge learned to solve the more complex problem of "finding what fraction of a number is known"; master some basic strategies for solving such problems in the process of solving the problem.

2. In the process of solving problems, realize the diversity of solution strategies, realize the close connection between the knowledge learned and real life, and develop students' application awareness.

3. Cultivate a sense of cooperation among students.

Self-study through reading and independent inquiry:

1. There are 540 tons of cargo at Baihai Freight Terminal. How many tons were transported on 5/9?

2. There are 540 tons of cargo at Baihai Freight Terminal, and 5/9 has been transported. How many tons are left?

Work in groups, discuss and resolve questions:

1. There is a batch of cargo at Baihai Freight Terminal. 5/9 and 300 tons of cargo were transported away. How many tons did this batch of cargo originally have?

2. There is a batch of cargo at Baihai Freight Terminal. 5/9 has been shipped away, leaving 240 tons. How many tons did this batch of cargo originally have?

Compare the two questions and draw the line segment graph and see what you find? How should it be solved?

300÷5/9=540(tons)

240÷ (1-5/9) =540(tons)

These two questions are all about finding what fraction of a number is known. The difference is: the former question directly corresponds to the tonnage transported and the transport fraction, while the latter question tells the transport fraction and the remaining tonnage, which means that the fraction and quantity are not. correspond.
