7、相邻体积单位之间的进率（7, the rate of entry between adjacent volume units）

7、相邻体积单位之间的进率（7, the rate of entry between adjacent volume units） In the rate of two adjacent volume between units Brief: The teaching content of this course is the course standard of education in Jiangsu version of Mathematics on page thirtieth of the sixth grade in 11 cases and the corresponding practice, practice seven questions 1-4. Through teaching, let students explore into the rate of two adjacent volume between units. And the conversion between units according to the experience of independent exploration. Through the comparison of the length of conversion units, unit of area, volume unit, communication unit conversion, help the students to grasp the conversion method of unit volume, skill formation. The concept of space observation of graphics and compare the development of students, training students thinking. The teaching process: The first section: review for 1: review the preparation process The second section: the example teaching 2: 11 cases of teaching process The third section: according to the practice Process 3: practice Process 4: complete seven practice first questions Process 5: complete seven practice second questions The fourth section: summary Process 6: summary Section fifth: classroom work Process 7: class assignments The first section: review for 1: review the preparation process 1, teacher: what is the length of the unit? What is the rate of two units between adjacent? (pause) Look: a unit of length Meter decimeter centimeter Teacher: what are the common area of the unit? What is the rate of two units between adjacent? (pause) Look: a unit of area Square meters square decimeter square centimeter 2, please look in, talk about how you think? (1) 2 meters (= =) cm (decimeter) (pause) Teacher: the unit meters to decimeter or centimeter, is the senior unit into a lower unit, as long as the use of advanced units in number by rate between them. Teach: Senior unit number * rate 2 x 10=20 (DM) 2 x 100=200 (CM) (2) 300 cm (= = (m)). (pause) Teacher
