The following is a simple demonstration example:
1, Introduction: First, introduce the concept of addition to students, that is, the process of adding two or more numbers to get a total. You can interest students with simple questions. For example, there are three apples and two apples, so how many apples are there in a * * *?
2. Demonstration: Suppose students are taught to calculate the result of 4+2. Use real objects, such as counting sticks, cards or icons, to demonstrate. Show four items, then add two items, and then ask students to count or point to the items together to help understand the meaning of addition.
3. Calculation: Guide students to add gradually. You can use a blackboard, whiteboard or calculator to show it. For example, write down 4+2=, and then ask students to fill in the results. Encourage students to calculate with their mouths or fingers, and provide help and guidance in the calculation process.
4. Practice: Give students some exercises to consolidate the skills of addition. You can use simple and specific questions, such as please calculate 2+3= or use pictures to indicate the number of items, so that students can add them up by themselves. Appropriate feedback and encouragement can be provided in practice.
5. Summary: Summarize the contents of this lecture and emphasize the basic concepts and operation rules of addition. Ask students some simple questions and check their understanding of addition. For example, there are 5 apples and 0 apples, so how many apples will there be in a * * *?
Significance of trial teaching
1. Evaluation of teaching ability: Trial teaching is a common way to recruit teachers or evaluate teachers' qualifications. Through the trial lecture, employers or reviewers can directly observe and evaluate the teaching ability, communication ability and teaching methods of candidates. This helps to determine whether the candidate has appropriate teaching skills and is qualified for the teaching position.
2. Show professional knowledge: The trial lecture provides an opportunity to show your professional knowledge and teaching skills. Teachers can demonstrate their understanding and mastery of the teaching content through clear explanation, demonstration and interaction. Trial lectures can reflect teachers' in-depth understanding of the course and their ability to transfer knowledge to students.
