新北师大版五年级数学上册练习二教案(直接打印版) Lesson 1 Teaching Content: Exercise 2 (Pages 19-20 of the textbook) Teaching Objectives: 1.To further enhance students mastery of the n method for decimal n through exercises. 2.To cultivate students ability to apply decimal n in practical ns and solve simple real-life problems. Teaching Focus: To master the n method for decimal n and apply it to solve practical problems. Teaching Difficulties: To help students appreciate the utility of n and cultivate their n awareness. Teaching Process: I。Setting the Scene Teacher: We are nearing the end of our study on decimal n。Today。lets assess your understanding of the unit and consolidate your knowledge through Exercise 2. II。Exploring New Knowledge 1.Display Exercise 2.n 1 on Page 19 of the textbook: ⑴。After reading the n。students compare and discuss in groups. Teacher: What patterns did you notice。students? ⑵。Students work in groups to write a set of ns。Display and correct the answers as a class. 2.Display Exercise 2.n 2 on Page 19 of the textbook: Teacher: What mathematical n did you find in the graph? After students understand the n。they work independently and discuss in groups。Have students present their ns and correct them as a class. 3.Display Exercise 2.n 3 on Page 19 of the textbook: First。have students calculate the n and then ask them to explain what each segment on the number line represents。Have students draw and estimate。Display the results. Teacher: How do we determine the n of the quotient? 4.Display Exercise 2.n 4 on Page 19 of the textbook: Have students work independently to calculate and verify。discuss and explain each step in groups。and display their homework. 5.Display Exercise 2.n 5 on Page 19 of the textbook: Teacher: How do we calculate the order of ns for mixed decimal arithmetic? Students discuss and work independently before correcting their answers as a class. Lesson 2 Teaching Content: Exercise 2 (Pages 19-20 of the textbook) Teaching Objectives: 1.To further enhance stu
