The content of the teacher recruitment lecture is generally to give you a textbook topic. You prepare lessons according to the requirements of textbooks and topics, and then give lectures, which are generally the contents of primary schools. The details can be determined according to the examination syllabus.

Let me show you a lecture on primary school mathematics:

Lecture notes on "A great deal of understanding in primary school mathematics"

First of all, talk about textbooks.

"Understanding of Tons" is the teaching content of Unit 4 "Understanding of Kilometers and Tons" in the sixth volume of the mathematics textbook for six-year primary schools with nine-year compulsory education. This class is a class hour. Before the teaching of this topic, students have a deep understanding of the unit of weight kilograms and grams, and can accurately convert the unit of weight kilograms and grams, which paves the way for the teaching content of this lesson. Through the teaching of this topic, students have a more comprehensive understanding and understanding of weight units. This is not only the need of industrial and agricultural production and daily life, but also lays the foundation for learning other knowledge in the future. According to the arrangement of teaching materials, outline requirements and students' cognitive characteristics, the teaching objectives of this course are determined as follows:

1. Students can understand the mass unit ton and establish the concept of 1 ton. Yes 1 ton = 1000 kg. And polymerization between mass units can be simplified.

2. Cultivating students' ability to estimate the quality of objects can solve corresponding problems in life.

Because the ton is a large unit of measurement, students often just see it, but they may not really feel it. Therefore, the focus of teaching is to establish the concept of 1 ton, and the difficulty is to cultivate students' ability to estimate the mass of objects. 1 ton is very abstract. How to make students accurately perceive the weight of 1 ton has become the breakthrough of this lesson.

Second, talk about teaching methods and learning methods.

Third, talk about teaching design.

The teaching procedure is divided into four parts:

1. Create a scenario and introduce a new course.

This link is mainly to review the old knowledge closely related to the new knowledge, naturally introduce new knowledge, stimulate students' learning motivation and mobilize students' learning enthusiasm. The design is as follows:

(1) courseware shows pictures of fruit trading market.

"An apple weighs 450 _ _ _ _ _, and a box of apples weighs15 _ _ _ _ (fill in the appropriate company name). It is estimated that the quality of a truckload of apples is 3 _ _ _ _. (Fill in the appropriate unit name)

(2) Know tons by things. The slide shows two pictures of trucks and railway wagons loaded with goods. )

The teacher guides the students: What is the meaning of ton or T on the picture?

(3) Reveal the concept of "ton"

Measure the mass of heavy objects or bulk objects, usually in tons (t).

(4) Reveal the ratio between tons and kilograms "1 ton =1000kg"

By creating situations, let students perceive the weight of tons in quantity and feedback how many students already know "tons". The concept of ton is introduced from the reality of life, which makes students feel that mathematics comes from life and can be found at any time in life.

2, physical experience, contact life

This link is gradually from abstract to concrete, mainly to deepen students' understanding and expand their thinking, so that students can fully feel that the quantity represented by tons is a heavy and intuitive object, laying the foundation for the next teaching.

(1) Showcase: a bag of 50kg rice and four 5kg shot puts.

The teacher asked the students to carry rice and weigh the shot put. Guide the students: 1 ton how many bags does this rice need? Can this rice carry 20 bags? The shot put process is the same as above.

(2) The deskmates tell each other their own weights, recite each other's backs, and feel the weight of 1 students. Teacher's guidance: 1 ton is equivalent to several of our classmates.

(3) Examples of contact with life

The design of this link embodies the teaching principle of teacher-oriented and student-centered, which fully enables students to actively participate in learning, feel and calculate by themselves with their brains, hands and mouths, which is beneficial for students to establish the concept of 1 ton and break through difficulties. Use the weight unit of tons in life and strengthen the concept construction of tons.

3. Unitization and merger.

(1) Show examples: 5 tons = () kg, 5 tons 680 kg = () kg.

2000kg = () tons, 2450kg = () tons () kilograms.

(2) Topic: The weight of a box of apples is 10 kg, the weight of a pair of dumbbells is 5 kg, the weight of a bag of flour is 25 kg, and the weight of a cow is 500 kg, so the weight of () is 1 ton.

Group discussion, the teacher participates in the student discussion.

4. Ask questions and summarize the class.

Let the students talk about what they have learned from this lesson.
