（教案）第二单元时、分、秒第2课时（2）-二年级数学
下册（苏教版）
教学目标：
1. 能够理解并掌握“时、分、秒”的基本概念。

2. 能够通过教师演示和学生操作，掌握“时、分、秒”的表达方法。

3. 能够在实际生活中应用所学的知识，正确阅读时间。

教学重点：
通过教师演示和学生操作，掌握“时、分、秒”的表达方法。

教学难点：
能够在实际生活中应用所学的知识，正确阅读时间。

教学方法：
任务型教学法
情境教学法
探究式学习法
教学过程：
Step1. Warming up
1. Good morning class. How are you today?
2. Today, we will learn about “time”. Who knows what time is?
3. Let’s watch a video about telling time.
4. Do you know what time it is now? Can you tell me?
Step 2. Introducing time
1. Now, let’s talk about the basic units of time. What are they?
2. Display a clock and explain the different parts of
it (hour hand, minute hand, second hand, numbers, etc.).
3. Ask students to identify the different parts of a clock.
4. Explain that the hour hand tells us the hour, the minute hand tells us the minutes, and the second hand tells us the seconds.
5. Demonstrate how to read the time on a clock to the nearest minute.
Step 3. Practice
1. Give students various clocks and ask them to read the time.
2. Have students practice telling time in pairs or small groups.
3. Play a game where students have to race to write down the correct time after the teacher calls out a time.
Step 4. Extension
1. Ask students to draw or create their own clocks.
2. Have students write down the time on each other's clocks.
3. Have students create word problems involving time
(e.g. If a student wakes up at 7:30am and it takes them 20 minutes to get dressed, what time do they leave for school?).
Step5. Conclusion
1. Review the key points of the lesson.
2. Ask students to share any new knowledge they learned about telling time.
3. Encourage students to continue practicing telling time at home.
教学反思：
本课时通过教师演示和学生操作，掌握“时、分、秒”的表达方法，并能在实际生活中应用所学的知识，正确阅读时间，实现了教学目标。

在教学过程中，通过任务型教学法和情境教学法，能更好地激发学生的学习兴趣，提高学生学习主动性和对课程内容的掌握程度。

同时，通过探究式学习法，让学生在实践中体验、探究，促进学生的自主学习和自我提高。
