Study preparation

Prepare notebooks and drafts, and record them while reading. Control the play in time and complete the corresponding exercises according to the teacher's guidance in class.

learning tasks

(1) Master the relationship between fraction and division, and establish the connection between knowledge.

(2) Applying the relationship between fraction and division to solve practical problems.

key link

Find the relationship between fraction and division through research and problem solving → complete the corresponding exercises → deepen the connection of knowledge → apply the relationship between fraction and division to solve practical problems.

Essence summary

As shown in the figure

Topics and analysis after class

Fill in the blanks.

1, cut the 3-meter-long wire into 8 segments on average, and each segment (? ) meters.

2、7÷5=

3 m (1) and 1 m (? ) the same length.

4. Divide a 4-square-meter round flower bed into five pieces with the same size, and each piece is (? ) square meters.

answer

1. Cut a 3-meter-long metal wire into 8 segments, each segment is (8(3)) meters long.

2、7÷5= (5(7))

3 m (1) of 3,4 is as long as 1 m of (4(3).

4. Divide a 4 square meter round flower bed into five pieces with the same size, each piece is (5(4)) square meters.

analyse

Master the relationship between fraction and division, dividend/divisor =? Divider (dividend)

Fill in the appropriate numbers in the brackets below.

37 points = (? ) 7: 00 yuan = (? )790dm3=(？ )m3

answer

37 points =( 100(37)) yuan 7: 00 =(24(7)) days 790dm3= (? 1000(790)) m3

The analysis topics are the conversion from low-level units to high-level units, and the accurate use of unit conversion rate. Master the relationship between fraction and division, dividend/divisor =? Divider (dividend).

Homework arrangement

1. Complete page 30 of "Learning the Law". Note: today's ability training questions should also be done. (Must be completed)

2. Take notes in math class, preferably a special notebook, for easy review and review. (Must be completed)

3. Seriously think about the arrangement of the network class teacher and tell parents what you think (choose to do it).
