For example:
Title: Factors and multiples
First, the teaching objectives:
1, understand factors and multiples, understand the concept of "coexistence" relationship, and master the method of finding factors and multiples of a certain number.
2, through individual independent thinking, group cooperation and discussion, explore the method of finding the factors and multiples of a certain number.
3. Stimulate the interest in learning mathematics and experience the charm of mathematics.
Second, the key points and difficulties
1, weight: the way to master the factor and multiple of a certain number.
2. Difficulties: Understand the concept of "reciprocity".
Third, the teaching process
1, newly granted:
Activity 1: 12 can be written several times to determine the relationship between factors and multiples-students think independently;
Activity 2: How to find out all the factors of 24, which cannot be repeated or omitted-students cooperate in groups and discuss actively;
Activity 3: Find the factor of 36-Ask two students to answer on the blackboard.
Step 2 consolidate
Practice doing the first question.
3. Summary
Ask two students to talk about their gains, and the teacher will supplement them.
4. Homework
(1) Finish the second and third questions;
(2) Compare the rankings after class to see who finds the right factor and find it quickly.
Interview procedure
1, to be tested. Candidates arrive at the test center on time with the interview admission ticket and identity documents, and enter the waiting room to wait for the exam.
2. Choose a topic. According to the arrangement of test sites, log in to the "interview evaluation software system" and extract a set of test questions from the question bank through the computer (kindergarten candidates choose 1 from the two extracted test questions, and only choose 1 for other categories). After the candidates confirm, the system will print the test paper and the list of test questions (the candidates must sign the list of test questions).
3. prepare lessons. Candidates enter the lesson preparation room with lesson preparation papers and test papers, write lesson plans (or activity demonstration plans), and prepare lessons for 20 minutes.
4. Answer the assigned questions. Candidates are guided by the staff to enter the designated interview room. The examiner randomly selects 2 prescribed questions from the question bank, and the candidates answer them for 5 minutes.
5. Trial/demonstration. Candidates give a trial lecture (or demonstration) according to the prepared teaching plan (or activity demonstration scheme). 10 minute.
Step 6 reply. The examiner will ask questions about the content and test items of the candidate's trial lecture (or demonstration), and the candidate will reply for 5 minutes. Candidates submit the list of test questions, prepare the teaching plan (activity demonstration plan) and leave.
7. Score. The examiner comprehensively scores the candidates' interview performance according to the scoring standard, fills in the interview scoring form, which is signed by the team leader and submitted through the interview evaluation system.
